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 third RSA private key representations and extends caampkc to use the fastest key when all related components are present in the private key.
