    Default customer charset in jtr


    I have searched the forums for an answer and only found a partial answer. How can I tell john to only use certain letters when cracking a password? For example I want john to crack my password using the character set ABCDEFGHIJKLMNOPRSTUVWXYabcdefghijklmnoprstuvwxy

    The partial answer I found to edit the [List.Rules:Wordlist] but I haven't figured out exactly what to change.
