|
|
This function validates \s-1RSA\s0 keys. It checks that \fBp\fR and \fBq\fR are
|
|
in fact prime, and that \fBn = p*q\fR.
|
|
.PP
|
|
It also checks that \fBd*e = 1 mod (p-1*q-1)\fR,
|
|
and that \fBdmp1\fR, \fBdmq1\fR and \fBiqmp\fR are set correctly or are \fB\s-1NULL\s0\fR.
|
|
.PP
|
|
The key's public components may not be \fB\s-1NULL\s0\fR.
|
|
.SH "RETURN VALUE"
|
|
.IX Header "RETURN VALUE"
|
|
\&\fIRSA_check_key()\fR returns 1 if \fBrsa\fR is a valid \s-1RSA\s0 key, and 0 otherwise.
|
|
\&\-1 is returned if an error occurs while checking the key.
|
|
.PP
|
|
If the key is invalid or an error occurred, the reason code can be
|
|
obtained using ERR_get_error(3).
