comment why gmail's phone verification code not encrypted
There is usually configurable rate-limiting for failed attempts on the server side. E.g. if you fail more than 3 times within 30 seconds, all further attempts will be ignored -- so the chance of a successful random guess is 1 in 33,333.

comment Public key encryption vs Digital signatures
You are still conflating a whole lot of concepts, but let me assure you that you always want to generate a hash. This is how digital signatures work -- a one-way hash of your entire message is computed (e.g. sha256) and then encrypted with your private key. Anyone who has your public key can then verify the message.

No, that's not what digital certificates are. Digital certificates are just your public keys signed by a certification authority. My answer stands -- in public key cryptography encryption by itself cannot be used for non-repudiation.

That's not actually a clarification, as digital certificates are USED to make digital signatures.

You're effectively asking what's faster -- a train or going by railroad.
