smf74,

I have forgotten my password, how can I recover it? RAR encryption does not contain backdoors, so the only possible way to find a password is to test all possible character combinations. Remember that if you lose your password, you will be unable to retrieve the encrypted files, not even the WinRAR author is able to extract encrypted files.

Единственный способ- это перебор всех возможных символьных комбинаций. (WinRAR не имеет бэкдоров).
