OpenBSD tool to signs and verify signatures on files. Portable version.
The signify utility creates and verifies cryptographic signatures.
A signature verifies the integrity of a message.
The key and signature files created by signify have the same format.
The first line of the file is a free form text comment that may be edited,
so long as it does not exceed a single line. Signature comments will be
generated based on the name of the secret key used for signing.
This comment can then be used as a hint for the name of the public key
when verifying. The second line of the file is the actual key or signature
base64 encoded.
