crypto: rsa - RSA padding algorithm
This patch adds PKCS#1 v1.5 standard RSA padding as a separate template. This way an RSA cipher with padding can be obtained by instantiating "pkcs1pad(rsa)". The reason for adding this is that RSA is almost never used without this padding (or OAEP) so it will be needed for either certificate work in the kernel or the userspace, and I also hear that it is likely implemented by hardware RSA in which case hardware implementations of the whole of pkcs1pad(rsa) can be provided.
