A digital signature is a mathematically generated code that validates the authenticity of a software, message, or digital file. It uses encryption techniques that are secure enough to be considered legal and binding in some countries. It guarantees that the file has not been altered during transmission, providing a layer of security against cyber threats and attacks.
When a person creates a digital signature, two additional encrypted files are created. These are the “private key” which stays with the signature owner, and the “public key” which is sent along with the signed document to let the recipient open it.
A digital signature is like a person’s thumbprint. It is undeniable proof of that person’s identity.
