Talisman searches for files that look suspicious — such as tokens, passwords, and private keys.
copied from cf-post-staging / talismanTalisman 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.
