minisign

A dead simple tool to sign files and verify signatures. More information: https://jedisct1.github.io/minisign/.

• Generate a new keypair at the default location:
  minisign -G
• Sign a file:
  minisign -Sm {{path/to/file}}
• Sign a file, adding a trusted (signed) and an untrusted (unsigned) comment in the signature:
  minisign -Sm {{path/to/file}} -c "{{Untrusted comment}}" -t "{{Trusted comment}}"
• Verify a file and the trusted comments in its signature using the specified public key file:
  minisign -Vm {{path/to/file}} -p {{path/to/publickey.pub}}
• Verify a file and the trusted comments in its signature, specifying a public key as a Base64 encoded literal:
  minisign -Vm {{path/to/file}} -P "{{public_key_base64}}"
