Description

Hello, Id like to request teamspeak 3 channel hash algorithm to john to use the full gpu power

The algorithm is base64(sha1(base64(sha1($pass))$virtualserver_keypair))

the virtualserver_keypair works as salt and could be supplied to the program

The hash could also be converted from base64 to hex to improve the speed

Research direction

No source file, test, or entry point is named. Start by tracing how John the Ripper represents salted password hashes and GPU-capable formats, then compare that path with the stated base64 and SHA-1 sequence and virtualserver_keypair salt. Done means the TeamSpeak 3 algorithm is supported with the supplied salt and uses the requested GPU path.
