=item "salt" (B<OSSL_KDF_PARAM_SALT>) <octet string>
Some KDF implementations can take a salt.
Some KDF implementations can take a non-secret unique cryptographic salt.
For those KDF implementations that support it, this parameter sets the salt.
The default value, if any, is implementation dependent.

=item "info" (B<OSSL_KDF_PARAM_INFO>) <octet string>
This parameter sets the info, fixed info, other info or shared info value.
Some KDF implementations, such as L<EVP_KDF-HKDF(7)>, take an 'info' parameter
for binding the derived key material
to application- and context-specific information.
This parameter sets the info, fixed info, other info or shared info argument.
You can specify this parameter multiple times, and each instance will
be concatenated to form the final value.
