rsa: document deprecated low level functions Reviewed-by: Richard Levitte <levitte@openssl.org> (Merged from https://github.com/openssl/openssl/pull/11063)
2020-02-12 13:23:01 +08:00
All of the functions described on this page are deprecated.
Applications should instead use EVP PKEY APIs.
Document the RSA library.

RSA_sign_ASN1_OCTET_STRING() signs the octet string B<m> of size
B<m_len> using the private key B<rsa> represented in DER using PKCS #1
padding. It stores the signature in B<sigret> and the signature size
in B<siglen>. B<sigret> must point to B<RSA_size(rsa)> bytes of
memory.
B<dummy> is ignored.
man: clarify the 'random number generator must be seeded' requirement The manual pages require for some API functions that the 'random number generator must be seeded' before calling the function. Initially, this was meant literally, i.e. the OpenSSL CSPRNG had to be seeded manually before calling these functions. Since version 1.1.1, the CSPRNG is seeded automatically on first use, so it's not the responsibility of the programmer anymore. Still, he needs to be aware that the seeding might fail.

The random number generator must be seeded when calling
RSA_sign_ASN1_OCTET_STRING().
If the automatic seeding or reseeding of the OpenSSL CSPRNG fails due to
external circumstances (see L<RAND(7)>), the operation will fail.
Document the RSA library.
2000-01-12 06:35:21 +08:00
RSA_verify_ASN1_OCTET_STRING() verifies that the signature B<sigbuf>
of size B<siglen> is the DER representation of a given octet string
B<m> of size B<m_len>. B<dummy> is ignored. B<rsa> is the signer's
public key.
=head1 RETURN VALUES
RSA_sign_ASN1_OCTET_STRING() returns 1 on success, 0 otherwise.
RSA_verify_ASN1_OCTET_STRING() returns 1 on successful verification, 0
otherwise.
Fix L<> content in manpages L<foo|foo> is sub-optimal If the xref is the same as the title, which is what we do, then you only need L<foo>. This fixes all 1457 occurrences in 349 files. Approximately. (And pod used to need both.) Reviewed-by: Richard Levitte <levitte@openssl.org>
