148 .IX Header "DESCRIPTION"
149 \&\fIRSA_sign_ASN1_OCTET_STRING()\fR signs the octet string \fBm\fR of size
150 \&\fBm_len\fR using the private key \fBrsa\fR represented in \s-1DER\s0 using \s-1PKCS\s0 #1
151 padding. It stores the signature in \fBsigret\fR and the signature size
152 in \fBsiglen\fR. \fBsigret\fR must point to \fBRSA_size(rsa)\fR bytes of
155 \&\fBdummy\fR is ignored.
157 The random number generator must be seeded prior to calling \fIRSA_sign_ASN1_OCTET_STRING()\fR.
159 \&\fIRSA_verify_ASN1_OCTET_STRING()\fR verifies that the signature \fBsigbuf\fR
160 of size \fBsiglen\fR is the \s-1DER\s0 representation of a given octet string
161 \&\fBm\fR of size \fBm_len\fR. \fBdummy\fR is ignored. \fBrsa\fR is the signer's
164 .IX Header "RETURN VALUES"
165 \&\fIRSA_sign_ASN1_OCTET_STRING()\fR returns 1 on success, 0 otherwise.
166 \&\fIRSA_verify_ASN1_OCTET_STRING()\fR returns 1 on successful verification, 0
169 The error codes can be obtained by \fIERR_get_error\fR\|(3).
