На python

Скрипт для восстановления пароля в Psi (не работает с Psi старше 0.13 - способ криптования не изменился, поменялся формат конфига) под Unix-совместимыми системами. Также должен функционировать и в MS Windows, но это не проверялось.

Отличие от оригинального файла в том, что из строки print jid, u"None" убраны Unicode-символы, чтобы скрипт работал в KOI8-R окружении ОС FreeBSD.
