If you’d like to give feedback please let me know at - otherwise, make a pull request! Google Chrome Where are the creds stored? My code is far from perfect and I’m still very much trying to learn. He’s written an awesome python script for decrypting Firefox passwords - but I’ve tried to stay away from replicating his code for the benefit of my own learning. I’d also like to add upfront that I relied heavily on lClevy’S diagram of Mozilla Password-Based Encryption for writing my own tool. Microsoft DPAPI, ASN.1, 3DES.) but I’ll include some good references for further research along the way rather than try to explain these in depth. Someday I might bother doing that, if it turns out anyone actually uses those browsers.ĭisclaimer - This post will gloss over a few topics (e.g. Based on the research/work that’s gone into building this tool, it would be pretty straightforward to add functionality for Internet Explorer/Edge credential decryption as well.
