minisign
A dead simple tool to sign files and verify signatures.
TLDR
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]"
