Please read this to stop thinking signing and encryption are related: https://security.stackexchange.com/a/87373/70830

They are related in the sense that encryption and signing algorithms use the same cryptographic operations. But the algorithms themselves are different, so having knowledge or faith in a certain encryption algorithm does not mean you have either in a related signing algorithm. They are separate domains.

What is being encrypted in ECDSA? Or in Ed25519? You are wrong. Read the link.

tinco did not claim that anything is being encrypted in ECDSA nor in Ed25519.
I reacted to "isn’t signing almost identical to encrypting" and "encryption and signing algorithms use the same cryptographic operations".
