pycrypto -- vulnerable ElGamal key generation

Dwayne C. Litzenberger of PyCrypto reports: In the ElGamal schemes for both encryption and signatures, g is supposed to be the generator of the entire Z^p group. However, in PyCrypto 2.5 and earlier, g is more simply the generator of a random sub-group of Z^p. The result is that the signature spa...
