|
|
\fIRSA_sign_ASN1_OCTET_STRING()\fR signs the octet string \fBm\fR of size
|
|
\fBm_len\fR using the private key \fBrsa\fR represented in DER using PKCS #1
|
|
padding. It stores the signature in \fBsigret\fR and the signature size
|
|
in \fBsiglen\fR. \fBsigret\fR must point to \fBRSA_size(rsa)\fR bytes of
|
|
memory.
|

.PP
|
|
\fBdummy\fR is ignored.
|
|
.PP
|
|
The random number generator must be seeded prior to calling \fIRSA_sign_ASN1_OCTET_STRING()\fR.
|
|
.PP
|
|
\fIRSA_verify_ASN1_OCTET_STRING()\fR verifies that the signature \fBsigbuf\fR
|
|
of size \fBsiglen\fR is the DER representation of a given octet string
|
|
\fBm\fR of size \fBm_len\fR. \fBdummy\fR is ignored. \fBrsa\fR is the signer's
|
|
public key.
|
|
.SH "RETURN VALUES"

\fIRSA_sign_ASN1_OCTET_STRING()\fR returns 1 on success, 0 otherwise.
