What do we say about this when it comes to min. value? Here are some facts:
- OpenSSL 0.9.8c supports a max modulus of 1024 bit length and a minimum of 512 bits (which we don't support because it's completely unsafe).
- OpenSSL 1.0.1f doesn't have a max. modulus to the best of my knowledge.
- FIPS 186-4 has recommendations on page 16 which allows 1024 bit length for the modulus for current usage while ecrypt recommends a minimum 2432 bits (So that means 3072 in our case because SP 800-57 list of recommended (L, N) pairs has L values of (1024, 2048, 3072) only.
