Class MDGenerator
- Cloneable, IRandom
A simple pseudo-random number generator that relies on a hash algorithm,
that (a) starts its operation by hashing a seed
, and then (b)
continuously re-hashing its output. If no hash algorithm name is specified
in the Map
of attributes used to initialise the instance then the
SHA-160 algorithm is used as the underlying hash function. Also, if no
seed
is given, an empty octet sequence is used.
