Digital signature
Türkçe: Dijital imza
A method of proving who a message came from and that it was not altered, using a value produced with a private key and verified with a public key.
// EXPLANATION
The signer processes the message digest (hash) with their private key; anyone can verify it with the public key. Certificates and software updates are protected by this mechanism.
