Digital signature is a mathematical technique used to validate the authenticity and integrity of a digital message or document. It’s a way of ensuring that the message or document has not been tampered with or altered in any way since it was originally created.
Digital signatures are important because they provide a secure way to verify the identity of the sender of a message or document, as well as the integrity of the message or document itself. This is especially important in electronic commerce and other online transactions, where it is essential to be able to trust the identity of the other party and the authenticity of the documents being exchanged.
There are a number of different ways to create a digital signature, but the most common method is to use a public-key infrastructure (PKI). A PKI consists of a trusted third party, known as a certificate authority (CA), that issues digital certificates to users. These certificates contain the user’s public key, which is used to encrypt messages and documents, and the user’s private key, which is used to decrypt messages and documents.
