Keycheck

Checks your repository for Ethereum private keys in the hexadecimal format. Meant to be used in a pre-commit hook.

Installation

shell cargo install keycheck

Usage

Manual

Check the current folder and all subfolders for private keys. Respects your .gitignore
Upon finding a private key, outputs the file and line number, but not the key itself. Exit code 0 for no keys, 1 for key(s) found.

shell keycheck

In a git pre-commit hook

```shell brew install lefthook

echo 'pre-commit: commands: keycheck: run: keycheck' > lefthook.yml

lefthook install ```

Ignoring files

keycheck respects a .keycheckignore file. Format is same as .gitignore, so globs, comments etc. work as expected.
