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"
