151 \& int RSA_sign_ASN1_OCTET_STRING(int dummy, unsigned char *m,

161 .IX Header "DESCRIPTION"
162 \&\fIRSA_sign_ASN1_OCTET_STRING()\fR signs the octet string \fBm\fR of size
163 \&\fBm_len\fR using the private key \fBrsa\fR represented in \s-1DER\s0 using \s-1PKCS\s0 #1
164 padding. It stores the signature in \fBsigret\fR and the signature size
165 in \fBsiglen\fR. \fBsigret\fR must point to \fBRSA_size(rsa)\fR bytes of
168 \&\fBdummy\fR is ignored.
170 The random number generator must be seeded prior to calling \fIRSA_sign_ASN1_OCTET_STRING()\fR.
172 \&\fIRSA_verify_ASN1_OCTET_STRING()\fR verifies that the signature \fBsigbuf\fR
173 of size \fBsiglen\fR is the \s-1DER\s0 representation of a given octet string
174 \&\fBm\fR of size \fBm_len\fR. \fBdummy\fR is ignored. \fBrsa\fR is the signer's
177 .IX Header "RETURN VALUES"
178 \&\fIRSA_sign_ASN1_OCTET_STRING()\fR returns 1 on success, 0 otherwise.
179 \&\fIRSA_verify_ASN1_OCTET_STRING()\fR returns 1 on successful verification, 0
182 The error codes can be obtained by ERR_get_error(3).
