CAAM RSA private key may have either of three representations.
1. The first representation consists of the pair (n, d), where the
components have the following meanings:
n the RSA modulus
d the RSA private exponent
2. The second representation consists of the triplet (p, q, d), where
the
components have the following meanings:
p the first prime factor of the RSA modulus n
q the second prime factor of the RSA modulus n
d the RSA private exponent
3. The third representation consists of the quintuple (p, q, dP, dQ,
qInv),
where the components have the following meanings:
p the first prime factor of the RSA modulus n
q the second prime factor of the RSA modulus n
dP the first factors's CRT exponent
dQ the second factors's CRT exponent
qInv the (first) CRT coefficient
The benefit of using the third or the second key form is lower
computational cost for the decryption and signature operations.
This patch adds support for the second RSA private key
representation.
