These functions implement \s-1RSA\s0 public key encryption and signatures

|
as defined in \s-1PKCS\s0 #1 v2.0 [\s-1RFC\s0 2437].
|
|
.PP
|
|
The \fB\s-1RSA\s0\fR structure consists of several \s-1BIGNUM\s0 components. It can
|
|
contain public as well as private \s-1RSA\s0 keys:
|
|
.PP
|
|
.Vb 13
|
|
\& struct
|
|
\& {
|
|
\& BIGNUM *n; // public modulus
|
|
\& BIGNUM *e; // public exponent
|
|
\& BIGNUM *d; // private exponent
|
|
\& BIGNUM *p; // secret prime factor
|
|
\& BIGNUM *q; // secret prime factor
|
|
\& BIGNUM *dmp1; // d mod (p-1)
|
|
\& BIGNUM *dmq1; // d mod (q-1)
|
|
\& BIGNUM *iqmp; // q^-1 mod p
|
|
\& // ...
|
|
\& };
|
|
\& RSA
|
|
.Ve
|
|
In public keys, the private exponent and the related secret values are
|
|
\&\fB\s-1NULL\s0\fR.
|
|
.PP
|
|
\&\fBp\fR, \fBq\fR, \fBdmp1\fR, \fBdmq1\fR and \fBiqmp\fR may be \fB\s-1NULL\s0\fR in private
|
|
keys, but the \s-1RSA\s0 operations are much faster when these values are
|
|
available.
