*) SSL_MODE_AUTO_RETRY is enabled by default. Applications that use blocking
I/O in combination with something like select() or poll() will hang. This
can be turned off again using SSL_CTX_clear_mode().
Many applications do not properly handle non-application data records, and
TLS 1.3 sends more of such records. Setting SSL_MODE_AUTO_RETRY works
around the problems in those applications, but can also break some.
It's recommended to read the manpages about SSL_read(), SSL_write(),
SSL_get_error(), SSL_shutdown(), SSL_CTX_set_mode() and
SSL_CTX_set_read_ahead() again.
[Kurt Roeckx]
*) When unlocking a pass phrase protected PEM file or PKCS#8 container, we
now allow empty (zero character) pass phrases.
[Richard Levitte]
*) Apply blinding to binary field modular inversion and remove patent
pending (OPENSSL_SUN_GF2M_DIV) BN_GF2m_mod_div implementation.
[Billy Bob Brumley]
*) Deprecate ec2_mult.c and unify scalar multiplication code paths for
binary and prime elliptic curves.
[Billy Bob Brumley]
*) Remove ECDSA nonce padding: EC_POINT_mul is now responsible for
constant time fixed point multiplication.
[Billy Bob Brumley]
*) Revise elliptic curve scalar multiplication with timing attack
defenses: ec_wNAF_mul redirects to a constant time implementation
when computing fixed point and variable point multiplication (which
in OpenSSL are mostly used with secret scalars in keygen, sign,
ECDH derive operations).
[Billy Bob Brumley, Nicola Tuveri, Cesar Pereida García,

*) Updated CONTRIBUTING
[Rich Salz]
*) Updated DRBG / RAND to request nonce and additional low entropy
randomness from the system.
[Matthias St. Pierre]
*) Updated 'openssl rehash' to use OpenSSL consistent default.
[Richard Levitte]
*) Moved the load of the ssl_conf module to libcrypto, which helps
loading engines that libssl uses before libssl is initialised.
[Matt Caswell]
*) Added EVP_PKEY_sign() and EVP_PKEY_verify() for EdDSA
[Matt Caswell]
*) Fixed X509_NAME_ENTRY_set to get multi-valued RDNs right in all cases.
[Ingo Schwarze, Rich Salz]
*) Added output of accepting IP address and port for 'openssl s_server'
[Richard Levitte]
*) Added a new API for TLSv1.3 ciphersuites:
SSL_CTX_set_ciphersuites()
SSL_set_ciphersuites()
[Matt Caswell]
*) Memory allocation failures consistenly add an error to the error
stack.
[Rich Salz]
*) Don't use OPENSSL_ENGINES and OPENSSL_CONF environment values
in libcrypto when run as setuid/setgid.
[Bernd Edlinger]
*) Load any config file by default when libssl is used.
[Matt Caswell]
*) Added new public header file <openssl/rand_drbg.h> and documentation
for the RAND_DRBG API. See manual page RAND_DRBG(7) for an overview.
[Matthias St. Pierre]
*) QNX support removed (cannot find contributors to get their approval
for the license change).
[Rich Salz]
*) TLSv1.3 replay protection for early data has been implemented. See the
SSL_read_early_data() man page for further details.
[Matt Caswell]
*) Separated TLSv1.3 ciphersuite configuration out from TLSv1.2 ciphersuite
configuration. TLSv1.3 ciphersuites are not compatible with TLSv1.2 and
below. Similarly TLSv1.2 ciphersuites are not compatible with TLSv1.3.
In order to avoid issues where legacy TLSv1.2 ciphersuite configuration
would otherwise inadvertently disable all TLSv1.3 ciphersuites the
configuration has been separated out. See the ciphers man page or the
SSL_CTX_set_ciphersuites() man page for more information.

in responder mode now supports the new "-multi" option, which

*) Support for TLSv1.3 added. Note that users upgrading from an earlier
version of OpenSSL should review their configuration settings to ensure
that they are still appropriate for TLSv1.3. In particular if no TLSv1.3
ciphersuites are enabled then OpenSSL will refuse to make a connection
unless (1) TLSv1.3 is explicitly disabled or (2) the ciphersuite
configuration is updated to include suitable ciphersuites. The DEFAULT
ciphersuite configuration does include TLSv1.3 ciphersuites. For further

Changes between 1.1.0h and 1.1.0i [xx XXX xxxx]
*) Fixed a text canonicalisation bug in CMS
Where a CMS detached signature is used with text content the text goes
through a canonicalisation process first prior to signing or verifying a
signature. This process strips trailing space at the end of lines, converts
line terminators to CRLF and removes additional trailing line terminators
at the end of a file. A bug in the canonicalisation process meant that
some characters, such as form-feed, were incorrectly treated as whitespace
and removed. This is contrary to the specification (RFC5485). This fix
could mean that detached text data signed with an earlier version of
OpenSSL 1.1.0 may fail to verify using the fixed version, or text data
signed with a fixed OpenSSL may fail to verify with an earlier version of
OpenSSL 1.1.0. A workaround is to only verify the canonicalised text data
and use the "-binary" flag (for the "cms" command line application) or set
the SMIME_BINARY/PKCS7_BINARY/CMS_BINARY flags (if using CMS_verify()).

Changes between 1.1.0g and 1.1.0h [27 Mar 2018]
*) Constructed ASN.1 types with a recursive definition could exceed the stack
Constructed ASN.1 types with a recursive definition (such as can be found
in PKCS7) could eventually exceed the stack given malicious input with
excessive recursion. This could result in a Denial Of Service attack. There
are no such structures used within SSL/TLS that come from untrusted sources
so this is considered safe.
This issue was reported to OpenSSL on 4th January 2018 by the OSS-fuzz
project.
(CVE-2018-0739)
[Matt Caswell]
*) Incorrect CRYPTO_memcmp on HP-UX PA-RISC
Because of an implementation bug the PA-RISC CRYPTO_memcmp function is
effectively reduced to only comparing the least significant bit of each
byte. This allows an attacker to forge messages that would be considered as
authenticated in an amount of tries lower than that guaranteed by the
security claims of the scheme. The module can only be compiled by the
HP-UX assembler, so that only HP-UX PA-RISC targets are affected.
This issue was reported to OpenSSL on 2nd March 2018 by Peter Waltenberg
(IBM).
(CVE-2018-0733)
[Andy Polyakov]
*) Add a build target 'build_all_generated', to build all generated files
and only that. This can be used to prepare everything that requires
things like perl for a system that lacks perl and then move everything
to that system and do the rest of the build there.
[Richard Levitte]
*) Backport SSL_OP_NO_RENGOTIATION
OpenSSL 1.0.2 and below had the ability to disable renegotiation using the
(undocumented) SSL3_FLAGS_NO_RENEGOTIATE_CIPHERS flag. Due to the opacity
changes this is no longer possible in 1.1.0. Therefore the new
SSL_OP_NO_RENEGOTIATION option from 1.1.1-dev has been backported to
1.1.0 to provide equivalent functionality.
Note that if an application built against 1.1.0h headers (or above) is run
using an older version of 1.1.0 (prior to 1.1.0h) then the option will be
accepted but nothing will happen, i.e. renegotiation will not be prevented.
[Matt Caswell]
*) Removed the OS390-Unix config target. It relied on a script that doesn't
exist.
