Bug Description

Textbook ElGamal, like textbook RSA, is insecure. (See e.g. https://bugs.launchpad.net/pycrypto/+bug/1005540)

  Therefore, the Crypto.PublicKey.ElGamal module can't be safely used as-is; It needs a padding scheme. PyCrypto has an appropriate padding scheme for RSA (PKCS1_OAEP); It would be nice if it had one for ElGamal also.
