SYNOPSIS

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

DESCRIPTION

21       RSA_sign_ASN1_OCTET_STRING() signs the octet string m of size m_len
22       using the private key rsa represented in DER using PKCS #1 padding. It
23       stores the signature in sigret and the signature size in siglen. sigret
24       must point to RSA_size(rsa) bytes of memory.
25
26       dummy is ignored.
27
28       The random number generator must be seeded prior to calling
29       RSA_sign_ASN1_OCTET_STRING().
30
31       RSA_verify_ASN1_OCTET_STRING() verifies that the signature sigbuf of
32       size siglen is the DER representation of a given octet string m of size
33       m_len. dummy is ignored. rsa is the signer's public key.

RETURN VALUES

36       RSA_sign_ASN1_OCTET_STRING() returns 1 on success, 0 otherwise.
37       RSA_verify_ASN1_OCTET_STRING() returns 1 on successful verification, 0
38       otherwise.
39
40       The error codes can be obtained by ERR_get_error(3).
