Driftwood is a tool that can enable you to lookup whether a private key is used for things like TLS or as a GitHub SSH key for a user.
Driftwood performs lookups with the computed public key, so the private key never leaves where you run the tool. Additionally it supports some basic password cracking for encrypted keys.
