EC_POINT_mul is a convenient interface to EC_POINTs_mul: it calculates the value generator * B<n> + B<q> * B<m> and stores the result in B<r>.
The value B<n> may be NULL in which case the result is just B<q> * B<m> (variable point multiplication). Alternatively, both B<q> and B<m> may be NULL, and B<n> non-NULL, in which case the result is just generator * B<n> (fixed point multiplication).

=head1 DESCRIPTION
These functions are generic support functions for all KDF algorithms.
EVP_PKEY_CTX_set1_pbe_pass() sets the password to the B<passlen> first
bytes from B<pass>.
=begin comment
We really should have a few more, such as EVP_PKEY_CTX_set1_kdf_salt,
EVP_PKEY_CTX_set1_kdf_key (to be used by the algorithms that use a
key, such as hkdf), EVP_PKEY_CTX_set1_kdf_md (same thing here).

=head1 STRING CTRLS
There is also support for string based control operations via
L<EVP_PKEY_CTX_ctrl_str(3)>.
The B<password> can be directly specified using the B<type> parameter
"pass" or given in hex encoding using the "hexpass" parameter.
=begin comment
Just as for the function description, the strings "salt", "hexsalt",
"key", "hexkey" and "md" should be generically specified, and
supported by the algorithms that use them.

=head1 DESCRIPTION
These are the functions that implement L<RSA-PSS(7)>.
=head2 Signing and Verification
The macro EVP_PKEY_CTX_set_rsa_padding() is supported but an error is
returned if an attempt is made to set the padding mode to anything other
than B<PSS>. It is otherwise similar to the B<RSA> version.
The EVP_PKEY_CTX_set_rsa_pss_saltlen() macro is used to set the salt length.
If the key has usage restrictions then an error is returned if an attempt is
made to set the salt length below the minimum value. It is otherwise similar
to the B<RSA> operation except detection of the salt length (using
RSA_PSS_SALTLEN_AUTO is not supported for verification if the key has
usage restrictions.
The EVP_PKEY_CTX_set_signature_md() and EVP_PKEY_CTX_set_rsa_mgf1_md() macros
are used to set the digest and MGF1 algorithms respectively. If the key has
usage restrictions then an error is returned if an attempt is made to set the
digest to anything other than the restricted value. Otherwise these are
similar to the B<RSA> versions.
=head2 Key Generation
As with RSA key generation the EVP_PKEY_CTX_set_rsa_rsa_keygen_bits()
and EVP_PKEY_CTX_set_rsa_keygen_pubexp() macros are supported for RSA-PSS:
they have exactly the same meaning as for the RSA algorithm.
Optional parameter restrictions can be specified when generating a PSS key.
If any restrictions are set (using the macros described below) then B<all>
parameters are restricted. For example, setting a minimum salt length also
restricts the digest and MGF1 algorithms. If any restrictions are in place
then they are reflected in the corresponding parameters of the public key
when (for example) a certificate request is signed.
EVP_PKEY_CTX_set_rsa_pss_keygen_md() restricts the digest algorithm the
generated key can use to B<md>.
EVP_PKEY_CTX_set_rsa_pss_keygen_mgf1_md() restricts the MGF1 algorithm the
generated key can use to B<md>.
EVP_PKEY_CTX_set_rsa_pss_keygen_saltlen() restricts the minimum salt length
to B<saltlen>.
=head1 NOTES
A context for the B<RSA-PSS> algorithm can be obtained by calling:
EVP_PKEY_CTX *pctx = EVP_PKEY_CTX_new_id(EVP_PKEY_RSA_PSS, NULL);

=head1 DESCRIPTION
These functions are used to set up the necessary data to use the
scrypt KDF.
For more information on scrypt, see L<scrypt(7)>.
EVP_PKEY_CTX_set1_scrypt_salt() sets the B<saltlen> bytes long salt
value.
EVP_PKEY_CTX_set_scrypt_N(), EVP_PKEY_CTX_set_scrypt_r() and
EVP_PKEY_CTX_set_scrypt_p() configure the work factors N, r and p.
EVP_PKEY_CTX_set_scrypt_maxmem_bytes() sets how much RAM key
derivation may maximally use, given in bytes.
If RAM is exceeded because the load factors are chosen too high, the
key derivation will fail.
=head1 STRING CTRLS
scrypt also supports string based control operations via
L<EVP_PKEY_CTX_ctrl_str(3)>.
Similarly, the B<salt> can either be specified using the B<type>
parameter "salt" or in hex encoding by using the "hexsalt" parameter.
The work factors B<N>, B<r> and B<p> as well as B<maxmem_bytes> can be
set by using the parameters "N", "r", "p" and "maxmem_bytes",
respectively.
=head1 NOTES
The scrypt KDF also uses EVP_PKEY_CTX_set1_pbe_pass() as well as
the value from the string controls "pass" and "hexpass".
See L<EVP_PKEY_CTX_set1_pbe_pass(3)>.
All the functions described here are implemented as macros.
=head1 RETURN VALUES
All these functions return 1 for success and 0 or a negative value for
failure.
In particular a return value of -2 indicates the operation is not

EVP_PKEY_free() decrements the reference count of B<key> and, if the reference
count is zero, frees it up. If B<key> is NULL, nothing is done.
EVP_PKEY_new_raw_private_key() allocates a new B<EVP_PKEY>. If B<e> is non-NULL
then the new B<EVP_PKEY> structure is associated with the engine B<e>. The
B<type> argument indicates what kind of key this is. The value should be a NID
for a public key algorithm that supports raw private keys, i.e. one of
B<EVP_PKEY_HMAC>, B<EVP_PKEY_POLY1305>, B<EVP_PKEY_SIPHASH>, B<EVP_PKEY_X25519>,
B<EVP_PKEY_ED25519>, B<EVP_PKEY_X448> or B<EVP_PKEY_ED448>. B<key> points to the
raw private key data for this B<EVP_PKEY> which should be of length B<keylen>.
The length should be appropriate for the type of the key. The public key data
will be automatically derived from the given private key data (if appropriate
for the algorithm type).
EVP_PKEY_new_raw_public_key() works in the same way as
EVP_PKEY_new_raw_private_key() except that B<key> points to the raw public key
data. The B<EVP_PKEY> structure will be initialised without any private key
information. Algorithm types that support raw public keys are
B<EVP_PKEY_X25519>, B<EVP_PKEY_ED25519>, B<EVP_PKEY_X448> or B<EVP_PKEY_ED448>.
EVP_PKEY_new_CMAC_key() works in the same way as EVP_PKEY_new_raw_private_key()
except it is only for the B<EVP_PKEY_CMAC> algorithm type. In addition to the
raw private key data, it also takes a cipher algorithm to be used during
creation of a CMAC in the B<cipher> argument.
EVP_PKEY_new_mac_key() works in the same way as EVP_PKEY_new_raw_private_key().
New applications should use EVP_PKEY_new_raw_private_key() instead.

=head1 NAME
RAND_DRBG_generate,
RAND_DRBG_bytes
- generate random bytes using the given drbg instance
=head1 SYNOPSIS
#include <openssl/rand_drbg.h>
int RAND_DRBG_generate(RAND_DRBG *drbg,
unsigned char *out, size_t outlen,
int prediction_resistance,
const unsigned char *adin, size_t adinlen);
int RAND_DRBG_bytes(RAND_DRBG *drbg,
unsigned char *out, size_t outlen);
=head1 DESCRIPTION
RAND_DRBG_generate() generates B<outlen> random bytes using the given
DRBG instance B<drbg> and stores them in the buffer at B<out>.
Before generating the output, the DRBG instance checks whether the maximum
number of generate requests (I<reseed interval>) or the maximum timespan
(I<reseed time interval>) since its last seeding have been reached.
If this is the case, the DRBG reseeds automatically.
Additionally, an immediate reseeding can be requested by setting the
B<prediction_resistance> flag to 1. See NOTES section for more details.
The caller can optionally provide additional data to be used for reseeding
by passing a pointer B<adin> to a buffer of length B<adinlen>.
This additional data is mixed into the internal state of the random
generator but does not contribute to the entropy count.
The additional data can be omitted by setting B<adin> to NULL and
B<adinlen> to 0;
RAND_DRBG_bytes() generates B<outlen> random bytes using the given
DRBG instance B<drbg> and stores them in the buffer at B<out>.
This function is a wrapper around the RAND_DRBG_generate() call,
which collects some additional data from low entropy sources
(e.g., a high resolution timer) and calls
RAND_DRBG_generate(drbg, out, outlen, 0, adin, adinlen).
=head1 RETURN VALUES
RAND_DRBG_generate() and RAND_DRBG_bytes() return 1 on success,
and 0 on failure.
=head1 NOTES
The I<reseed interval> and I<reseed time interval> of the B<drbg> are set to
reasonable default values, which in general do not have to be adjusted.
If necessary, they can be changed using L<RAND_DRBG_set_reseed_interval(3)>
and L<RAND_DRBG_set_reseed_time_interval(3)>, respectively.
A request for prediction resistance can only be satisfied by pulling fresh
entropy from one of the approved entropy sources listed in section 5.5.2 of
[NIST SP 800-90C].
Since the default DRBG implementation does not have access to such an approved
entropy source, a request for prediction resistance will always fail.
In other words, prediction resistance is currently not supported yet by the DRBG.

RAND_DRBG *RAND_DRBG_get0_public(void);
RAND_DRBG *RAND_DRBG_get0_private(void);
=head1 DESCRIPTION
The default RAND API implementation (RAND_OpenSSL()) utilizes three
shared DRBG instances which are accessed via the RAND API:
The <public> and <private> DRBG are thread-local instances, which are used
by RAND_bytes() and RAND_priv_bytes(), respectively.
The <master> DRBG is a global instance, which is not intended to be used
directly, but is used internally to reseed the other two instances.
These functions here provide access to the shared DRBG instances.
=head1 RETURN VALUES
RAND_DRBG_get0_master() returns a pointer to the <master> DRBG instance.
RAND_DRBG_get0_public() returns a pointer to the <public> DRBG instance.
RAND_DRBG_get0_private() returns a pointer to the <private> DRBG instance.
=head1 NOTES
It is not thread-safe to access the <master> DRBG instance.
The <public> and <private> DRBG instance can be accessed safely, because
they are thread-local. Note however, that changes to these two instances
apply only to the current thread.
For that reason it is recommended not to change the settings of these
three instances directly.
Instead, an application should change the default settings for new DRBG instances
at initialization time, before creating additional threads.
During initialization, it is possible to change the reseed interval
and reseed time interval.
It is also possible to exchange the reseeding callbacks entirely.
=head1 HISTORY
The RAND_DRBG functions were added in OpenSSL 1.1.1.

=head1 DESCRIPTION
RAND_DRBG_new() and RAND_DRBG_secure_new()
create a new DRBG instance of the given B<type>, allocated from the heap resp.
the secure heap
(using OPENSSL_zalloc() resp. OPENSSL_secure_zalloc()).
RAND_DRBG_set() initializes the B<drbg> with the given B<type> and B<flags>.
RAND_DRBG_set_defaults() sets the default B<type> and B<flags> for new DRBG
instances.
Currently, all DRBG types are based on AES-CTR, so B<type> can be one of the
following values: NID_aes_128_ctr, NID_aes_192_ctr, NID_aes_256_ctr.
Before the DRBG can be used to generate random bits, it is necessary to set
its type and to instantiate it.
The optional B<flags> argument specifies a set of bit flags which can be
joined using the | operator. Currently, the only flag is
RAND_DRBG_FLAG_CTR_NO_DF, which disables the use of a the derivation function
ctr_df. For an explanation, see [NIST SP 800-90A Rev. 1].
If a B<parent> instance is specified then this will be used instead of
the default entropy source for reseeding the B<drbg>. It is said that the
B<drbg> is I<chained> to its B<parent>.
For more information, see the NOTES section.
RAND_DRBG_instantiate()
seeds the B<drbg> instance using random input from trusted entropy sources.
Optionally, a personalization string B<pers> of length B<perslen> can be
specified.
To omit the personalization string, set B<pers>=NULL and B<perslen>=0;
RAND_DRBG_uninstantiate()
clears the internal state of the B<drbg> and puts it back in the
uninstantiated state.
=head1 RETURN VALUES
RAND_DRBG_new() and RAND_DRBG_secure_new() return a pointer to a DRBG
instance allocated on the heap, resp. secure heap.
RAND_DRBG_set(),
RAND_DRBG_instantiate(), and
RAND_DRBG_uninstantiate()
return 1 on success, and 0 on failure.
RAND_DRBG_free() does not return a value.
=head1 NOTES
The DRBG design supports I<chaining>, which means that a DRBG instance can
use another B<parent> DRBG instance instead of the default entropy source
to obtain fresh random input for reseeding, provided that B<parent> DRBG
instance was properly instantiated, either from a trusted entropy source,
or from yet another parent DRBG instance.
For a detailed description of the reseeding process, see L<RAND_DRBG(7)>.
The default DRBG type and flags are applied only during creation of a DRBG
instance.
To ensure that they are applied to the global and thread-local DRBG instances
(<master>, resp. <public> and <private>), it is necessary to call
RAND_DRBG_set_defaults() before creating any thread and before calling any
cryptographic routines that obtain random data directly or indirectly.

=head1 DESCRIPTION
RAND_DRBG_reseed()
reseeds the given B<drbg>, obtaining entropy input from its entropy source
and mixing in the specified additional data provided in the buffer B<adin>
of length B<adinlen>.
The additional data can be omitted by setting B<adin> to NULL and B<adinlen>
to 0.
RAND_DRBG_set_reseed_interval()
sets the reseed interval of the B<drbg>, which is the maximum allowed number
of generate requests between consecutive reseedings.
If B<interval> > 0, then the B<drbg> will reseed automatically whenever the
number of generate requests since its last seeding exceeds the given reseed
interval.
If B<interval> == 0, then this feature is disabled.
RAND_DRBG_set_reseed_time_interval()
sets the reseed time interval of the B<drbg>, which is the maximum allowed
number of seconds between consecutive reseedings.
If B<interval> > 0, then the B<drbg> will reseed automatically whenever the
elapsed time since its last reseeding exceeds the given reseed time interval.
If B<interval> == 0, then this feature is disabled.
RAND_DRBG_set_reseed_defaults() sets the default values for the reseed interval
(B<master_reseed_interval> and B<slave_reseed_interval>)
and the reseed time interval
(B<master_reseed_time_interval> and B<slave_reseed_tme_interval>)
of DRBG instances.
The default values are set independently for master DRBG instances (which don't
have a parent) and slave DRBG instances (which are chained to a parent DRBG).
=head1 RETURN VALUES
RAND_DRBG_reseed(),
RAND_DRBG_set_reseed_interval(), and
RAND_DRBG_set_reseed_time_interval(),
return 1 on success, 0 on failure.
=head1 NOTES
The default OpenSSL random generator is already set up for automatic reseeding,
so in general it is not necessary to reseed it explicitly, or to modify
its reseeding thresholds.
Normally, the entropy input for seeding a DRBG is either obtained from a
trusted os entropy source or from a parent DRBG instance, which was seeded
(directly or indirectly) from a trusted os entropy source.
In exceptional cases it is possible to replace the reseeding mechanism entirely
by providing application defined callbacks using RAND_DRBG_set_callbacks().
The reseeding default values are applied only during creation of a DRBG instance.
To ensure that they are applied to the global and thread-local DRBG instances
(<master>, resp. <public> and <private>), it is necessary to call
RAND_DRBG_set_reseed_defaults() before creating any thread and before calling any
cryptographic routines that obtain random data directly or indirectly.

=head1 DESCRIPTION
RAND_DRBG_set_callbacks() sets the callbacks for obtaining fresh entropy and
the nonce when reseeding the given B<drbg>.
The callback functions are implemented and provided by the caller.
Their parameter lists need to match the function prototypes above.
Setting the callbacks is allowed only if the DRBG has not been initialized yet.
Otherwise, the operation will fail.
To change the settings for one of the three shared DRBGs it is necessary to call
RAND_DRBG_uninstantiate() first.
The B<get_entropy>() callback is called by the B<drbg> when it requests fresh
random input.
It is expected that the callback allocates and fills a random buffer of size
B<min_len> <= size <= B<max_len> (in bytes) which contains at least B<entropy>
bits of randomness.
The B<prediction_resistance> flag indicates whether the reseeding was
triggered by a prediction resistance request.
The buffer's address is to be returned in *B<pout> and the number of collected
randomness bytes as return value.
If the callback fails to acquire at least B<entropy> bits of randomness,
it must indicate an error by returning a buffer length of 0.
If B<prediction_resistance> was requested and the random source of the DRBG
does not satisfy the conditions requested by [NIST SP 800-90C], then
it must also indicate an error by returning a buffer length of 0.
See NOTES section for more details.
The B<cleanup_entropy>() callback is called from the B<drbg> to to clear and
free the buffer allocated previously by get_entropy().
The values B<out> and B<outlen> are the random buffer's address and length,
as returned by the get_entropy() callback.
The B<get_nonce>() and B<cleanup_nonce>() callbacks are used to obtain a nonce
and free it again. A nonce is only required for instantiation (not for reseeding)
and only in the case where the DRBG uses a derivation function.
The callbacks are analogous to get_entropy() and cleanup_entropy(),
except for the missing prediction_resistance flag.
If the derivation function is disabled, then no nonce is used for instantiation,
and the B<get_nonce>() and B<cleanup_nonce>() callbacks can be omitted by
setting them to NULL.
=head1 RETURN VALUES
RAND_DRBG_set_callbacks() return 1 on success, and 0 on failure
=head1 NOTES
It is important that B<cleanup_entropy>() and B<cleanup_nonce>() clear the buffer
contents safely before freeing it, in order not to leave sensitive information
about the DRBG's state in memory.
A request for prediction resistance can only be satisfied by pulling fresh
entropy from one of the approved entropy sources listed in section 5.5.2 of
[NIST SP 800-90C].
Since the default implementation of the get_entropy callback does not have access
to such an approved entropy source, a request for prediction resistance will
always fail.
In other words, prediction resistance is currently not supported yet by the DRBG.
The derivation function is disabled during initialization by calling the
RAND_DRBG_set() function with the RAND_DRBG_FLAG_CTR_NO_DF flag.
For more information on the derivation function and when it can be omitted,
see [NIST SP 800-90A Rev. 1]. Roughly speeking it can be omitted if the random
source has "full entropy", i.e., contains 8 bits of entropy per byte.
Even if a nonce is required, the B<get_nonce>() and B<cleanup_nonce>()
callbacks can be omitted by setting them to NULL.
In this case the DRBG will automatically request an extra amount of entropy
(using the B<get_entropy>() and B<cleanup_entropy>() callbacks) which it will
utilize for the nonce, following the recommendations of [NIST SP 800-90A Rev. 1],
section 8.6.7.

Random numbers are a vital part of cryptography, including key generation,
creating salts, etc., and software-based
generators must be "seeded" with external randomness before they can be
used as a cryptographically-secure pseudo-random number generator (CSPRNG).
The availability of common hardware with special instructions and
modern operating systems, which may use items such as interrupt jitter
and network packet timings, can be reasonable sources of seeding material.
These functions can be used to seed the random generator and to check its
seeded state.
In general, manual (re-)seeding of the default OpenSSL random generator
(L<RAND_OpenSSL(3)>) is not necessary (but allowed), since it does (re-)seed
itself automatically using trusted system entropy sources.
This holds unless the default RAND_METHOD has been replaced or OpenSSL was
built with automatic reseeding disabled, see L<RAND(7)> for more details.
RAND_status() indicates whether or not the CSPRNG has been sufficiently
seeded. If not, functions such as RAND_bytes(3) will fail.

The new OpenSSL DRBG has some peculiarities which need to be taken

when RAND_get_rand_method() == RAND_OpenSSL().
This applies in particular to the way reseeding is done by the DRBG:
=over 2

The DRBG seeds itself automatically, pulling random input from trusted
entropy sources.
Automatic reseeding occurs after a predefined number of generate requests.
The selection of the trusted entropy sources is configured at build
time using the --with-rand-seed option.

The DRBG distinguishes two different types of random input:
'entropy', which comes from a trusted source, and 'additional input',
which can optionally be added by the user and is considered untrusted.

=head2 DRBG with automatic seeding enabled
Calling RAND_poll() or RAND_add() is not necessary, because the DRBG
polls the entropy source automatically.
However, both calls are permitted, and do reseed the RNG.
RAND_add() can be used to add both kinds of random input, depending on the
value of the B<randomness> argument:
=over 4

The random bytes are mixed as additional input into the current state of
the DRBG.
Mixing in additional input is not considered a full reseeding, hence the
reseed counter is not reset.

The random bytes are used as entropy input for a full reseeding
(resp. reinstantiation) if the DRBG is instantiated
(resp. uninstantiated or in an error state).
A reseeding requires 16 bytes (128 bits) of randomness.
It is possible to provide less randomness than required.
In this case the missing randomness will be obtained by pulling random input
from the trusted entropy sources.

=head1 DESCRIPTION
SSL_CTX_set_num_tickets() and SSL_set_num_tickets() can be called for a server
application and set the number of session tickets that will be sent to the
client after a full handshake. Set the desired value (which could be 0) in the
B<num_tickets> argument. Typically these functions should be called before the
start of the handshake.
The default number of tickets is 2; the default number of tickets sent following
a resumption handshake is 1 but this cannot be changed using these functions.
The number of tickets following a resumption handshake can be reduced to 0 using
custom session ticket callbacks (see L<SSL_CTX_set_session_ticket_cb(3)>).
Tickets are also issued on receipt of a post-handshake certificate from the
client following a request by the server using
L<SSL_verify_client_post_handshake(3)>. These new tickets will be associated
with the updated client identity (i.e. including their certificate and
verification status). The number of tickets issued will normally be the same as
was used for the initial handshake. If the initial handshake was a full
handshake then SSL_set_num_tickets() can be called again prior to calling
SSL_verify_client_post_handshake() to update the number of tickets that will be
sent.
SSL_CTX_get_num_tickets() and SSL_get_num_tickets() return the number of
tickets set by a previous call to SSL_CTX_set_num_tickets() or
SSL_set_num_tickets(), or 2 if no such call has been made.
=head1 RETURN VALUES
SSL_CTX_set_num_tickets() and SSL_set_num_tickets() return 1 on success or 0 on
failure.
SSL_CTX_get_num_tickets() and SSL_get_num_tickets() return the number of tickets
that have been previously set.

Many systems implement Nagle's algorithm by default which means that it will
buffer outgoing TCP data if a TCP packet has already been sent for which no
corresponding ACK has been received yet from the peer. This can have performance
impacts after a successful TLSv1.3 handshake or a successful TLSv1.2 (or below)
resumption handshake, because the last peer to communicate in the handshake is
the client. If the client is also the first to send application data (as is
typical for many protocols) then this data could be buffered until an ACK has
been received for the final handshake message.
The B<TCP_NODELAY> socket option is often available to disable Nagle's
algorithm. If an application opts to disable Nagle's algorithm consideration
should be given to turning it back on again later if appropriate. The helper
function BIO_set_tcp_ndelay() can be used to turn on or off the B<TCP_NODELAY>

=head1 REPLAY PROTECTION
When early data is in use the TLS protocol provides no security guarantees that
the same early data was not replayed across multiple connections. As a
mitigation for this issue OpenSSL automatically enables replay protection if the
server is configured with a non-zero max early data value. With replay
protection enabled sessions are forced to be single use only. If a client
attempts to reuse a session ticket more than once, then the second and
subsequent attempts will fall back to a full handshake (and any early data that
was submitted will be ignored). Note that single use tickets are enforced even
if a client does not send any early data.
The replay protection mechanism relies on the internal OpenSSL server session
cache (see L<SSL_CTX_set_session_cache_mode(3)>). By default sessions will be
added to the cache whenever a session ticket is issued. When a client attempts
to resume the session OpenSSL will check for its presence in the internal cache.
If it exists then the resumption is allowed and the session is removed from the
cache. If it does not exist then the resumption is not allowed and a full
handshake will occur.
Note that some applications may maintain an external cache of sessions (see
L<SSL_CTX_sess_set_new_cb(3)> and similar functions). It is the application's
responsibility to ensure that any sessions in the external cache are also
populated in the internal cache and that once removed from the internal cache
they are similarly removed from the external cache. Failing to do this could
result in an application becoming vulnerable to replay attacks. Note that
OpenSSL will lock the internal cache while a session is removed but that lock is
not held when the remove session callback (see L<SSL_CTX_sess_set_remove_cb(3)>)
is called. This could result in a small amount of time where the session has
been removed from the internal cache but is still available in the external
cache. Applications should be designed with this in mind in order to minimise
the possibility of replay attacks.
The OpenSSL replay protection does not apply to external Pre Shared Keys (PSKs)
(e.g. see SSL_CTX_set_psk_find_session_callback(3)). Therefore extreme caution
should be applied when combining external PSKs with early data.
