There was recently an instance where a user was confused by the deprecation warnings in the docs. They believed the warning applied to the immediately preceding function declarations, when it fact it applied to the following function declarations. https://mta.openssl.org/pipermail/openssl-users/2021-December/014665.html We clarify the wording to make it clear that the warning applies to the following functions.

=head1 NAME
|
|
|
|
RSA_sign_ASN1_OCTET_STRING, RSA_verify_ASN1_OCTET_STRING - RSA signatures
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/rsa.h>
|
|
|
|
The following functions have been deprecated since OpenSSL 3.0, and can be
|
|
hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value,
|
|
see L<openssl_user_macros(7)>:
|
|
|
|
int RSA_sign_ASN1_OCTET_STRING(int dummy, unsigned char *m,
|
|
unsigned int m_len, unsigned char *sigret,
|
|
unsigned int *siglen, RSA *rsa);
|
|
|
|
int RSA_verify_ASN1_OCTET_STRING(int dummy, unsigned char *m,
|
|
unsigned int m_len, unsigned char *sigbuf,
|
|
unsigned int siglen, RSA *rsa);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
All of the functions described on this page are deprecated.
|
|
Applications should instead use EVP PKEY APIs.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
The error codes can be obtained by L<ERR_get_error(3)>.
|
|
|
|
=head1 BUGS
|
|
|
|
These functions serve no recognizable purpose.
