Re: Bug#742145: openssl: uses only 32 bytes (256 bit) for key generation

2014-03-19 Thread Joey Hess
The amount of seed material required to generate a cryptographic key equals the effective key size of the key. For example, a 3072-bit RSA or Diffie-Hellman private key has an effective key size of 128 bits (it requires about 2^128 operations to break) so a key gene
