What is a digital signature and how is one used in PKI?
What will be an ideal response?
A digital signature is a numeric string created by a cryptographic algorithm, called a "hash," that's used to validate a message or document's authenticity. The signature is verified by an algorithm that uses the stated owner of the signature's public key to accept or reject the signature as authentic. In a PKI, a certification authority's digital signature is used to verify the authenticity of digital certificates and other documents.
