Random Numbers

With the exception of cert-new, any BX command that requires a random number obtains that value as an argument. This places the responsibility of ensuring random number strength on end-users and also helps them understand the potential for problems.

The cert-new command uses platform random number generation due to its reliance on the underlying Curve ZMQ implementation.

The seed command is provided as a convenience, and is the only command that generates randomness.

$ bx seed --bit_length 256

BX utilizes libbitcoin's deterministic ECDSA and as such requires no seed for signing.
