minisign

A dead simple tool to sign files and verify signatures.

TLDR

Generate a new keypair at the default location

$ minisign -G
copy

Sign a file

$ minisign -Sm [path/to/file]
copy

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]"
copy

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]
copy

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]"
copy
