Important organizational announcement Due to feedback from several people who wish to contribute, this project is being moved to it's own repository. The master copy is now at SalusaSecondus/CryptoGotchas. This will let us more easily take PRs/Issues and track contributions.
The version on this Gist will be preserved for a bit to make it easier to discover, but I encourage you to update your links. (A redirect page will remain indefinitely.)
