Signify - Ed25519 signature tool

Create cryptographic signatures for files and verify them. This is based on signify, the OpenBSD tool to sign and verify signatures on files. It is based on the Ed25519 public-key signature system by Bernstein et al.

Installation

cargo install signify

Usage

Create a key pair:

signify -G -p pubkey -s seckey

Sign a file using the secret key:

signify -S -s seckey -m README.md

Verify the signature:

signify -V -p pubkey -m README.md

Limitations

• No embedded signatures
• No password-protection for secret keys

Both things will be implemented eventually. I also accept PRs.
