Digital Signatures

Digital signatures rely on the use of public key cryptography, which generally allows users to communicate securely without having prior access to a shared secret key. Digital signatures can be used to ensure the authenticity of a sender. For example, Bob can encrypt a message with his private key and send it to Alice. If Alice can successfully decrypt it using the corresponding public key, this provides assurance to Alice that Bob (and no one else) sent it.
