Sometimes you encounter encrypted (or password-protected) RARs.
Supposing you know the required password, you can tell it to SABnzbd before the download starts post-processing.
You can do it in two ways:
In the NZB file name you can embed the password like this: "My Job {{PW}}.nzb".
This will set the the job name to "My Job" and the password to "PW".
You can rename the job in the queue.
"My Job / PASSWORD" will set the password. The '/' is used as a separator because it cannot be part of a folder name.
The folder name will be "My Job" and "PASSWORD" will be used as the decryption password when unpacking.
The password can be changed until the job enters the post-processing queue.
