Electronic contracts use public key cryptography, third-party CA digital authentication technology and timestamp technology to generate reliable electronic signatures, which are secure and tamper-proof.

The Electronic Signature Law clarifies the legality and validity of electronic signatures:

Article 3 In civil activities, the parties may agree on the use or non-use of electronic signatures and data messages in contracts or other documents and materials.

Article 14 A reliable electronic signature has the same legal effect as a handwritten signature or seal.
