How to generate a secret key with Python. GitHub Gist: instantly share code, notes, and snippets.
No ads, popups or nonsense, just a random hex generator. Press a button, get a hex number. This example generates sixteen random hexadecimals of length 32, which are effectively random MD5 hashes. We don't send a single bit about your input data to our servers. There is no server-side processing at all.
