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 [http://darkk.net.ru/home/bin/psi-pass-dump.py оригинального файла] в том, что из строки ''print jid, u"None"'' убраны Unicode-символы, чтобы скрипт работал в KOI8-R окружении ОС FreeBSD.
