+The \fB\s-1RSA\s0\fR keytype is implemented in OpenSSL's default and \s-1FIPS\s0 providers.
+That implementation supports the basic \s-1RSA\s0 keys, containing the modulus \fIn\fR,
+the public exponent \fIe\fR, the private exponent \fId\fR, and a collection of prime
+factors, exponents and coefficient for \s-1CRT\s0 calculations, of which the first
+few are known as \fIp\fR and \fIq\fR, \fIdP\fR and \fIdQ\fR, and \fIqInv\fR.
+.SS "Common \s-1RSA\s0 parameters"

+In addition to the common parameters that all keytypes should support (see
+\&\*(L"Common parameters\*(R" in \fBprovider\-keymgmt\fR\|(7)), the \fB\s-1RSA\s0\fR keytype implementation
+supports the following.

+For \s-1RSA\s0 keys, \fBEVP_PKEY_public_check\fR\|(3) conforms to the SP800\-56Br1 \fIpublic key

+performs similar tests but relaxes the keysize restrictions for backwards

+For \s-1RSA\s0 keys, \fBEVP_PKEY_public_check_quick\fR\|(3) is the same as
