How does the public-key encrypted message hash provide a better digital signature?

In what way does the public-key encrypted message hash provide a better digital signature than the public-key encrypted message? 13. A public-key signed message digest is "better" in that one need only encrypt (using the private key) a short message digest, rather than the entire message. Since public

What is a public key in cryptography?

In a public-key cryptosystem, a public key is a key that can be used for verifying digital signatures generated using a corresponding private key. In some cryptosystems, public keys can also be used for encrypting messages so that they can only be decrypted using the corresponding private key.

What is a cryptographic hash?

A cryptographic hash (sometimes called 'digest') is a kind of 'signature' for a text or a data file. SHA-512 generates an almost-unique 512-bit (32-byte) signature for a text.
