stretch
stretch is a command line tool that uses PBKDF2 from Python’s passlib to derive a key, given a secret and a salt.
Installation
You can, of course, clone the repo or download the stretch.py script and call it from its directory, but I’d rather have it “installed” so it can be called from anywhere. The easiest way to install it:
[sudo] pip install stretch
Instead, you could just copy the script to a convenient location:
[sudo] curl https://raw.githubusercontent.com/felipedau/stretch/master/stretch/stretch.py -o /usr/local/bin/stretch
Finally, stretch the secret foo with the salt bar using the defaults hmac-sha512 and 10000 rounds:
$ stretch foo bar FUMV4GHTdgpdEbseRSkUNiTd6CYktCUr3XPqy+pp7cPk7R7Ho0L1JJDXMbcYQkA/gkWQ7BoSOtRcMnvnD8qqhg==
