(EC)DSA signature fix (#670) * Write a test - signatures with EC keys (#609) * Ask for signature length before allocating a buffer. This fixes a potential heap buffer overflow that may happen when a signature is longer than the private key, as with X9.62 ECDSA (#609). * change approach to EVP_PKEY_size and add changelog * add a small assert
