=head1 NAME
openssl-info,
info - print OpenSSL built-in information
=head1 SYNOPSIS
B<openssl info>
[B<-help>]
[B<-configdir> | B<-c>]
[B<-enginesdir> | B<-e>]
[B<-modulesdir> | B<-m>]
[B<-dsoext>]
[B<-dirfilesep>]
[B<-listsep]>
=head1 DESCRIPTION
This command is used to print out information about OpenSSL.
The information is written exactly as it is with no extra text, which
makes useful for scripts.
As a consequence, only one item may be chosen for each run of this
command.
=head1 OPTIONS
=over 4
=item B<-help>
Print out a usage message.
=item B<-configdir>, B<-c>
Outputs the default directory for OpenSSL configuration files.
=item B<-enginesdir>, B<-e>
Outputs the default directory for OpenSSL engine modules.
=item B<-modulesdir>, B<-m>
Outputs the default directory for OpenSSL dynamically loadable modules
other than engine modules.
=item B<-dsoext>
Outputs the DSO extension OpenSSL uses.
=item B<-dirnamesep>
Outputs the separator character between a directory specification and
a file name.
Note that on some operating systems, this is not the same as the
separator between directory elements.
=item B<-listsep>
Outputs the OpenSSL list separator character.
This is typically used to construct C<$PATH> (C<%PATH%> on Windows)
style lists.
=back
=head1 HISTORY
The B<openssl info> command was added in OpenSSL 3.0.

=head1 NAME
openssl-kdf,
kdf - perform Key Derivation Function operations
=head1 SYNOPSIS
B<openssl kdf>
[B<-help>]
[B<-kdfopt> I<nm:v>]
[B<-keylen> I<num>]
[B<-out> I<filename>]
[B<-binary>]
I<kdf_name>
=head1 DESCRIPTION
The key derivation functions generate a derived key from either a secret or
password.
=head1 OPTIONS
=over 4
=item B<-help>
Print a usage message.
=item B<-keylen> I<num>
The output size of the derived key. This field is required.
=item B<-out> I<filename>
Filename to output to, or standard output by default.
=item B<-binary>
Output the derived key in binary form. Uses hexadecimal text format if not specified.
=item B<-kdfopt> I<nm:v>
Passes options to the KDF algorithm.
A comprehensive list of controls can be found in the EVP_KDF_CTX implementation
documentation.
Common control strings used by EVP_KDF_ctrl_str() are:
=over 4
=item B<key:>I<string>
Specifies the secret key as an alphanumeric string (use if the key contains
printable characters only).
The string length must conform to any restrictions of the KDF algorithm.
A key must be specified for most KDF algorithms.
=item B<hexkey:>I<string>
Specifies the secret key in hexadecimal form (two hex digits per byte).
The key length must conform to any restrictions of the KDF algorithm.
A key must be specified for most KDF algorithms.
=item B<pass:>I<string>
Specifies the password as an alphanumeric string (use if the password contains
printable characters only).
The password must be specified for PBKDF2 and scrypt.
=item B<hexpass:>I<string>
Specifies the password in hexadecimal form (two hex digits per byte).
The password must be specified for PBKDF2 and scrypt.
=item B<digest:>I<string>
Specifies the name of a digest as an alphanumeric string.
To see the list of supported digests, use the command I<list -digest-commands>.
=back
=item I<kdf_name>
Specifies the name of a supported KDF algorithm which will be used.
The supported algorithms names are TLS1-PRF, HKDF, SSKDF, PBKDF2, SSHKDF and id-scrypt.
=back
=head1 EXAMPLES
Use TLS1-PRF to create a hex-encoded derived key from a secret key and seed:
openssl kdf -keylen 16 -kdfopt digest:SHA256 -kdfopt key:secret \
-kdfopt seed:seed TLS1-PRF
Use HKDF to create a hex-encoded derived key from a secret key, salt and info:
openssl kdf -keylen 10 -kdfopt digest:SHA256 -kdfopt key:secret \
-kdfopt salt:salt -kdfopt info:label HKDF
Use SSKDF with KMAC to create a hex-encoded derived key from a secret key, salt and info:
openssl kdf -keylen 64 -kdfopt mac:KMAC128 -kdfopt maclen:20 \
-kdfopt hexkey:b74a149a161545 -kdfopt hexinfo:348a37a2 \
-kdfopt hexsalt:3638271ccd68a2 SSKDF
Use SSKDF with HMAC to create a hex-encoded derived key from a secret key, salt and info:
openssl kdf -keylen 16 -kdfopt mac:HMAC -kdfopt digest:SHA256 \
-kdfopt hexkey:b74a149a -kdfopt hexinfo:348a37a2 \
-kdfopt hexsalt:3638271c SSKDF
Use SSKDF with Hash to create a hex-encoded derived key from a secret key, salt and info:
openssl kdf -keylen 14 -kdfopt digest:SHA256 \
-kdfopt hexkey:6dbdc23f045488 \
-kdfopt hexinfo:a1b2c3d4 SSKDF
Use SSHKDF to create a hex-encoded derived key from a secret key, hash and session_id:
openssl kdf -keylen 16 -kdfopt digest:SHA256 \
-kdfopt hexkey:0102030405 \
-kdfopt hexxcghash:06090A \
-kdfopt hexsession_id:01020304 \
-kdfopt type:A SSHKDF
Use PBKDF2 to create a hex-encoded derived key from a password and salt:
openssl kdf -keylen 32 -kdfopt digest:SHA256 -kdfopt pass:password \
-kdfopt salt:salt -kdfopt iter:2 PBKDF2
Use scrypt to create a hex-encoded derived key from a password and salt:
openssl kdf -keylen 64 -kdfopt pass:password -kdfopt salt:NaCl \
-kdfopt N:1024 -kdfopt r:8 -kdfopt p:16 \
-kdfopt maxmem_bytes:10485760 id-scrypt
=head1 NOTES
The KDF mechanisms that are available will depend on the options
used when building OpenSSL.
