XAdES

XAdES (XML Advanced Electronic Signatures) is a standard that adds trusted digital signatures to XML documents, ensuring their authenticity, integrity, and non-repudiation. It allows organizations to securely sign electronic files in a way that proves the document hasn't been altered and confirms the signer’s identity. XAdES signatures are legally recognized in many jurisdictions and are commonly used in legal, governmental, and financial transactions to maintain secure, verifiable records electronically.
