XAdES (XML Advanced Electronic Signatures)

XAdES (XML Advanced Electronic Signatures) is a digital signature standard used to securely sign XML documents. It ensures the authenticity, integrity, and non-repudiation of the data, meaning the signed document is genuine, unchanged, and the signer cannot deny their involvement. XAdES adds specific information and cryptographic details to a standard digital signature, making it legally valid and trusted for official and legal transactions. It's widely used in secure digital communications, e-government, and business processes where document authenticity is crucial.
