Signing

`keys sign`

Sign image.png creates image.png.sig (armored, detached, Saltpack signature):

keys sign -s gabriel@github -i image.png

Create a signed message from stdin (armored, attached, saltpack signature):

echo -n "I'm gabriel on Github 🤓" | keys sign -s gabriel@github > msg.signed

Override the default format with -armor -attached and create an armored signed message for a file, image.png.signed:

keys sign -s gabriel@github -i image.png -armor -attached

For files, the default is armored, detached. For stdin, the default is armored, attached.

Input	Armored	Detached
file	Yes	Yes
stdin	Yes	No

Saltpack version 2 signing is currently the only output format.

Verify image.png from image.png.sig (detached signature).

keys verify -i image.png -x image.png.sig

cat msg.signed | keys verify -signer gabriel@github

Verify image.png.signed (attached) was signed by gabriel@github and create image.png.

keys verify -i image.png.signed -s gabriel@github
