Talisman

Talisman is a tool that installs a hook to your repository to ensure that potential secrets or sensitive information do not leave the developer's workstation. It validates the outgoing changeset for things that look suspicious - such as potential SSH keys, authorization tokens, private keys etc. Talisman can also be used as a repository history scanner to detect secrets that have already been checked in, so that you can take an informed decision to safeguard secrets. We recommend installing Talisman as a pre-commit git hook template, as that will cause Talisman to be present, not only in your existing git repositories, but also in any new repository that you 'init' or 'clone'. Installation of Talisman globally does not clobber pre-existing hooks on repositories. If the installation script finds any existing hooks, it will only indicate so on the console. After the installation is successful, Talisman will run checks for obvious secrets automatically before each commit or push.
