Electronic signature is a broad concept, and digital signature can be regarded as a way to realize electronic signature, which provides higher functions than the basic requirements of electronic signature.
If someone wants to send an important document to people in other places through the Internet, both the recipient and the sender need to apply for an electronic license from the licensing authority CA(GlobalSign). This encryption certificate includes the applicant's public key on the Internet, that is, the "public computer password", which is used for file verification.
The sender encrypts the file with the public key of the receiver issued by CA, and signs the file with its own key. When the recipient receives the file, he first analyzes the signature with the sender's public key to prove that the file is indeed sent by the sender. Then use your own private key to decrypt the file and read it.
In China, the Measures for the Administration of Electronic Certification Services promulgated by the Ministry of Industry and Information Technology stipulates that "if the electronic signature needs third-party certification, the legally established electronic certification service provider shall provide certification services". For the electronic certification service provider, namely CA (Digital Certification Authority), it is necessary to obtain the industrial and commercial registration license of the Ministry of Industry and Information Technology and meet the requirements of the Administrative Measures for Electronic Certification Services. At present, 42 certification bodies in China have obtained CA certificates. CA has the right to use the electronic signature certificate (electronic signature) of the electronic signer as a nationally recognized digital certificate.
According to Article 14 of People's Republic of China (PRC) Electronic Signature Law, "a reliable electronic signature has the same legal effect as a handwritten signature or seal."
