9 #include <openssl/rsa.h>
10
11 int RSA_sign_ASN1_OCTET_STRING(int dummy, unsigned char *m,
12    unsigned int m_len, unsigned char *sigret, unsigned int *siglen,
13    RSA *rsa);
14
15 int RSA_verify_ASN1_OCTET_STRING(int dummy, unsigned char *m,
16    unsigned int m_len, unsigned char *sigbuf, unsigned int siglen,
17    RSA *rsa);

19=head1 DESCRIPTION
20
21RSA_sign_ASN1_OCTET_STRING() signs the octet string B<m> of size
22B<m_len> using the private key B<rsa> represented in DER using PKCS #1
23padding. 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)|ERR_get_error(3)>.
