RSA_sign_ASN1_OCTET_STRING(3)                      OpenSSL                     RSA_sign_ASN1_OCTET_STRING(3)



NAME
       RSA_sign_ASN1_OCTET_STRING, RSA_verify_ASN1_OCTET_STRING - RSA signatures

SYNOPSIS
        #include <openssl/rsa.h>

        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);

DESCRIPTION
       RSA_sign_ASN1_OCTET_STRING() signs the octet string m of size m_len using the private key rsa
       represented in DER using PKCS #1 padding. It stores the signature in sigret and the signature size in
       siglen. sigret must point to RSA_size(rsa) bytes of memory.

       dummy is ignored.

       The random number generator must be seeded prior to calling RSA_sign_ASN1_OCTET_STRING().

       RSA_verify_ASN1_OCTET_STRING() verifies that the signature sigbuf of size siglen is the DER
       representation of a given octet string m of size m_len. dummy is ignored. rsa is the signer's public
       key.

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 ERR_get_error(3).

BUGS
       These functions serve no recognizable purpose.
