Cryptographic Best Practices

Putting cryptographic primitives together is a lot like putting a jigsaw puzzle together, where all the pieces are cut exactly the same way, but there is only one correct solution. Thankfully, there are some projects out there that are working hard to make sure developers are getting it right.

The following advice comes from years of research from leading security researchers, developers, and cryptographers. This Gist was [forked from Thomas Ptacek's Gist][1] to be more readable. Additions have been added from

If anyone is interested in setting up their system to automatically (or manually) sign their git commits with their GPG key, here are the steps:

Generate and add your key to GitHub
$ git config --global commit.gpgsign true ([OPTIONAL] every commit will now be signed)
$ git config --global user.signingkey ABCDEF01 (where ABCDEF01 is the fingerprint of the key to use)
$ git config --global alias.logs "log --show-signature" (now available as $ git logs)
$ git config --global alias.cis "commit -S" (optional if global signing is false)
$ echo "Some content" >> example.txt
$ git add example.txt
$ git cis -m "This commit is signed by a GPG key." (regular commit will work if global signing is enabled)
