Hi Marvin,

Each key is 45 random (assuming /dev/random is random) base-64 characters. So
the entropy available per key is 64^45 = 1.897x10^81. 256 bits of entropy is
one in 2^256 = 1.157920e+77 which is all that ever gets used (think of it as a
combination lock with 2^256 possibilities). So in fact there is plenty of
entropy, good enough for a 256 bit key - the actual key used is likely the
SHA-256 hash of the plain text key anyhow - Jari can confirm.

Cheers,
