WebThe data is signed by hashing the message with a hashing algorithm and the sender’s private key. This produces a hash digest, which can only be recreated through use of one of the keys in the key pair created by the sender. The recipient then receives the message, the hash digest, and the public key, if they did not already have it. Web3 hours ago · Teams. Q&A for work.

It's not signing (‘sign with the RSA private key’) if there's no hashing—hashing is an integral part of signing, not just a preprocessing step needed only to compress long messages, and in modern schemes like Ed25519 the hashing involves the private key itself. Also OAEP is not relevant to signature. shunta lowery
