PGP signature verfication

[jdgregson]

I am unable to verify a PGP-signed message in CyberChef. Using the only operation that seems like it should do this, "PGP Decrypt and Verify", asks for the public key of signer and private key of recipient. However, I simply want to verify the PGP signature of a message which is not encrypted. Given the following message, how can I verify that the signature matches the signed text, and possibly receive details such as the certificate's fingerprint and signer's name?

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

Can't verify this?
-----BEGIN PGP SIGNATURE-----
