comment Is there a “brainwallet” for GPG keys?
This shouldn’t be that difficult to made. All one need is crypto secure, password based, deterministic "random" source.

CRC is guaranteed since it uses primitive polynomial. Primitive polynomials are generators of finite field and that mean that CRC can have any value between 1 and 2^N
