minisign - 0.11-1 main

Minisign is a dead 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).
