[Дополнение] Утилита для генерации SRP хешей

This utility, written in python, generates SRP hashes for Warcraft 3 & pvpgn 1.99.x

These values are stored in BNET\acct\salt and BNET\acct\verifier.

If you enter salt and the correct password, verifier should match.
-------------------------------------------------------------------------------

Которые хранятся в BNET\acct\salt и BNET\acct\verifier.

Написана на питоне. Если ввести соль и правильный пароль, verifier должен совпасть.
