Hash signing
WebSep 7, 2016 · Code signing and verification works as follows. In addition to writing the code, the author executes a hash function with the code as the input, producing a digest. The digest is signed with the author’s private key, producing the signature. The code, signature and hash function are then delivered to the verifier.
