Computes and returns a 20-byte (160-bit) hash of the specified binary message. Each call will return a new byte array object instance.

Parameters

msg	the message to compute the hash of

Returns: a 20-byte array representing the message's RIPEMD-160 hash

Exceptions

NullPointerException

if the message is

null
