     RSA_sign_ASN1_OCTET_STRING() signs the octet string mmmm of
     size mmmm_lllleeeennnn using the private key rrrrssssaaaa represented in DER
     using PKCS #1 padding. It stores the signature in ssssiiiiggggrrrreeeetttt and
     the signature size in ssssiiiigggglllleeeennnn. ssssiiiiggggrrrreeeetttt must point to
     RRRRSSSSAAAA_ssssiiiizzzzeeee((((rrrrssssaaaa)))) bytes of memory.

     dddduuuummmmmmmmyyyy 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
     ssssiiiiggggbbbbuuuuffff of size ssssiiiigggglllleeeennnn is the DER representation of a given
     octet string mmmm of size mmmm_lllleeeennnn. dddduuuummmmmmmmyyyy is ignored. rrrrssssaaaa is the
     signer's public key.

     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).

     These functions serve no recognizable purpose.
