PBKDF2 on the command line

Project Description

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

Optional Arguments Description
-h, --help show this help message and exit
-b BEGIN, --begin BEGIN define where to start slicing the result (equivalent to result[b:])
-e END, --end END define where to stop slicing the result (equivalent to result[:e])
-f {md5,sha1,sha256,sha512}, --family {md5,sha1,sha256,sha512} choose a pseudo-random family.
-r ROUNDS, --rounds ROUNDS define the number of rounds to use on the generation (an integer greater than zero). (Default: 10000)
-c, --copy copy the output to the clipboard by piping it to xclip instead of printing
