Yes! Here I want to talk about China's Electronic Signature Law, in which Article 14 stipulates that "a reliable electronic signature has the same legal effect as a handwritten signature or seal". "Reliability" in legal provisions refers to the following four requirements for electronic signatures:

First, when the electronic signature production data is used for electronic signature, it belongs to the electronic signer;

Second, when signing, the electronic signature production data is only controlled by the electronic signer;

Third, any changes to the electronic signature after signing can be found;

Fourth, any changes to the content and form of data messages after signing can be found.

It is understood that 5G Quick Sign ensures the security and legality of electronic signature through digital certificate (CA certificate), hash digest, trusted timestamp and other technologies. The signing process of 5G Express Sign requires authentication. The digital certificate is issued by China Financial Certification Center. The contents of the certificate include: public key user information, public key, authority signature, etc. Through digital certificate, user identification and electronic information encryption can be realized. Time stamp is also a trusted time stamp authentication provided by the National Time Service Center of Chinese Academy of Sciences and the Joint Trusted Time Stamp Service Center, which ensures that the identity of the document signed by 5G Express Sign is true, the intention is true, the original text has not been changed, and the signature has not been changed, and it has legal effect.
