Digital Signature​

A digital signature is a cryptographic technique used to verify the authenticity and integrity of digital documents or messages. It is a mathematical scheme that uses a public key algorithm to create a digital signature, which can be verified using a corresponding public key.The process of creating a digital signature involves using a private key to encrypt a hash value of the message or document being signed. The recipient can then use the corresponding public key to verify the digital signature, which involves decrypting the hash value and comparing it to a newly computed hash value of the message or document. If the two hash values match, then the digital signature is considered valid, and the authenticity and integrity of the message or document are verified.
