Minisign – sign files and verify signatures

Minisign is a very simple tool to sign files and verify signatures.

It is portable, lightweight, and uses the highly secure Ed25519 public-key signature system.

Signature files include an untrusted comment line that can be freely modified, even after signature creation.

They also include a second comment line, that cannot be modified without the secret key.

Trusted comments can be used to add instructions or application-specific metadata (intended file name, timestamps, resource identifiers, version numbers to prevent downgrade attacks).

This is free and open source software.

Features include:

• Cross-platform support – runs under Linux, macOS, and Windows.

Minisign is written in C. Learn C with our recommended free books and free tutorials.
