RSA Verify Refactor
Browse files Browse the repository at this point in the history
1. If the signature to verify is short, pad it to the key length with
   leading zeros. Some implementations of SSH will prune leading zeros
   from an mpint value as a string for the signature.
2. Change some of the GetSize() and play with pointers to using
   GetStringRef() or GetMpint().
3. Added an RSA private key for testing with PuTTY client.
