How it works

Type /pass [some passphrase here] into Hain. The passgen plugin takes your input string, appends a unique salt string to it, and then generates a hash. The resulting hash is then base91 encoded so that it uses all uppercase and lowercase letters, numbers, and standard symbols. A subset of 15-100 (default is 40 and can be changed in preferences) characters is picked from the base91 encoded hash and then placed in your clipboard to be pasted into a password field.

Every time you use the same input string, you will get the same result from the passgen plugin. This allows you to use an easy to remember passphrases to generate lengthy, complicated passwords that no one can reproduce unless they know your passphrase, salt, and method of generating passwords.
