It stores the signature in B<sigret> and the signature size 24in B<siglen>. B<sigret> must point to B<RSA_size(rsa)> bytes of 25memory. 26 27B<dummy> is ignored. 28 29The random number generator must be seeded prior to calling RSA_sign_ASN1_OCTET_STRING(). 30 31RSA_verify_ASN1_OCTET_STRING() verifies that the signature B<sigbuf> 32of size B<siglen> is the DER representation of a given octet string 33B<m> of size B<m_len>. B<dummy> is ignored. B<rsa> is the signer's 34public key. 35 36=head1 RETURN VALUES 37 38RSA_sign_ASN1_OCTET_STRING() returns 1 on success, 0 otherwise. 39RSA_verify_ASN1_OCTET_STRING() returns 1 on successful verification, 0 40otherwise. 41 42The error codes can be obtained by L<ERR_get_error(3)>. 43 44=head1 BUGS 45 46These functions serve no recognizable purpose. 47 48=head1 SEE ALSO 49 50L<ERR_get_error(3)>, 51L<RAND_bytes(3)>, L<RSA_sign(3)>, 52L<RSA_verify(3)> 53 54=head1 COPYRIGHT 55 56Copyright 2000-2016 The OpenSSL Project Authors.
