RSAsignASN1OCTETSTRING(3) OpenSSL RSAsignASN1OCTETSTRING(3)

NAME
       RSAsignASN1OCTETSTRING, RSAverifyASN1OCTETSTRING - RSA
       signatures

SYNOPSIS
        #include 

        int RSAsignASN1OCTETSTRING(int dummy, unsigned char *m,
           unsigned int mlen, unsigned char *sigret, unsigned int *siglen,
           RSA *rsa);

        int RSAverifyASN1OCTETSTRING(int dummy, unsigned char *m,
           unsigned int mlen, unsigned char *sigbuf, unsigned int siglen,
           RSA *rsa);

DESCRIPTION
       RSAsignASN1OCTETSTRING() signs the octet string mm of size mmlleenn
       using the private key rrssaa represented in DER using PKCS #1 padding. It
       stores the signature in ssiiggrreett and the signature size in ssiigglleenn. ssiiggrreett
       must point to RRSSAAssiizzee((rrssaa)) bytes of memory.

       dduummmmyy is ignored.

       The random number generator must be seeded prior to calling
       RSAsignASN1OCTETSTRING().

       RSAverifyASN1OCTETSTRING() verifies that the signature ssiiggbbuuff of
       size ssiigglleenn is the DER representation of a given octet string mm of size
       mmlleenn. dduummmmyy is ignored. rrssaa is the signer's public key.

RETURN VALUES
       RSAsignASN1OCTETSTRING() returns 1 on success, 0 otherwise.
       RSAverifyASN1OCTETSTRING() returns 1 on successful verification, 0
       otherwise.

       The error codes can be obtained by ERRgeterror(3).

BUGS
       These functions serve no recognizable purpose.
