Encryption signature.

A digital signature is a cryptographic mechanism used to verify the authenticity and integrity of digital data. We may consider it as a digital version of the ordinary handwritten signatures, but with higher levels of complexity and security.

In a digital signature system, a sender can use a private key together with a message to create a signature. Anyone with the ...

The process works by using algorithms and cryptographic keys to encrypt and decrypt data. Two common types of cryptography are symmetric (private key cryptography) and asymmetric (public key cryptography).
