What Is The Process Of Digital Signature?

It is a block of data at the end of an electronic message that attests to the authenticity of the message. Digital signatures are an actual transformation of an electronic message using public key cryptography. It requires a key pair (private key for encryption and public key for decryption) and a hash function (algorithm). Digital signature is a two way process, involving two parties: signer (creator of the digital signature) and the recipient (verifier of the digital signature). A digital signature is complete, if and only if, the recipient successfully verifies it.
