What is the technology used in preparing digital signature?

Digital signatures are created using public key infrastructure (PKI) technology. They rely on asymmetric encryption, where a private key signs the document and a public key verifies it.

Digital certificates issued by Certifying Authorities (CAs) play a crucial role in validating the signer’s identity.
