I wrote a small python script that can decrypt cisco type 7 passwords.
Cisco7Decrypt on Github
You can decrypt password directly through the CLI:
→ python cisco7decrypt.py 12090404011C03162E password
If you want the command accessible from anywhere, just link it to a folder that’s included in your Path. In this example ‘~/bin’
ln -sn `pwd`/cisco7decrypt.py ~/bin/cisco7decrypt
