How to operate electronic signature

Electronic signatures, like physical signatures, need to be applied for and used.

However, due to the characteristics of "electronic and online", it is necessary to ensure the legal effect of electronic signature through CA digital certificate, time stamp and data encryption.

Generally speaking, we will apply for and use electronic signature with CA digital certificate through the third-party electronic signature platform, which is mainly divided into three steps: applying for seal, setting seal and using seal.

1. Apply for seal

First of all, we need to apply for a digital certificate through an authoritative CA organization, which is similar to our offline filing.

Before using the electronic seal, users need to carry out real-name authentication, and compare the business license, agent authorization certificate, bank card, ID card, mobile phone number, face recognition and other information with authoritative data sources to confirm that the identity of the signature subject is true and valid, and then the CA certification body issues a digital certificate to prove it.

Through such a real-name authentication link, it can be guaranteed that the electronic seal has the functions of identifying the signer's identity, approving the signature content and signing and stamping, and the contract content cannot be tampered with.

Secondly, after the authentication is passed, the platform will automatically create a default electronic seal for users and have a unique CA digital certificate.

In addition, due to the use of electronic seals, it can be subdivided into electronic official seals, electronic articles and electronic private seals. Therefore, the electronic contract platform generally supports the creation of custom electronic seals. The seal administrator of an enterprise can upload a picture of the official seal of the enterprise to generate a reliable electronic official seal, or customize the seal content (seal text, size, color, etc.). ).

Since this is a virtual digital file, the electronic seal is usually stored in a third-party cloud (cloud digital certificate) or entity ukey.

Step 3 use seals

Finally, after the successful creation of the electronic seal, the user can complete the authentication of the signature intention by entering the signature password or brushing his face, and then sign the seal.

In addition, the electronic contract signed with the seal can verify the authenticity of the CA digital certificate and confirm the authenticity of the signer, signing time, certificate number and other information of the seal.
