How can I test crypt password, or how can I unobfuscate password from config?

The config only contains an obfuscated password though, for instance, if I run that command rclone config dump I am still presented with the original password I used for my latest new crypt entry (let's call it crypt2. And this is expected, as rclone saves the obfuscated password, but what I am trying to obtain is the original password for crypt1 that the obfuscated password is derived from.

When doing the backup for a crypted remote, rclone's documentation states that the password must be the same between the two remotes, and while I have the obfuscated password, if I were to ever loose that obfuscated password I would loose access to the entire share. Where as if I had the original password, I could come up with the obfuscated password again.

The server-side-across-configs does seem interesting, I will start reading that.
