WebA version of the Mersenne Twister available in many programming languages, MT19937, has an impressive period of 219937 -1. Sequences with too short a period can be observed, recorded, and reused by an attacker. Sequences with long periods force the adversary to select alternate attack methods. safety requirement specification example
