Electronic signatures are more than a convenience — they are a foundation for digital trust. At the heart of a legally binding e-signature are three principles: authenticity, integrity, and non-repudiation.
Authenticity means knowing who signed. Integrity ensures that the content has not changed since signing. Non-repudiation provides proof that the signer cannot credibly deny the act. These properties are achieved through digital certificates, cryptographic hashes, and trusted timestamps.
Modern signature standards such as PAdES, XAdES, and CAdES ensure interoperability and legal compliance across borders. Aligning technology with frameworks like eIDAS or local trust laws allows organizations to adopt digital signing with confidence.
