    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.

    HISTORY

    RSA_sign_ASN1_OCTET_STRING() and RSA_verify_ASN1_OCTET_STRING() were added in SSLeay 0.8.
