+Package sshsig implements signing/verifying armored SSH signatures.
+You can use this package to sign data and verify signatures using your ssh private keys or your ssh agent.
+It gives the same output as using `ssh-keygen`, eg when signing `ssh-keygen -Y sign -f keyfile -n namespace data`
+
+This code is based upon work by https://github.com/sigstore/rekor
