In fact, manufacturers who make electronic signatures can make electronic signatures.

Moreover, electronic signatures have become popular in recent years, and many third-party electronic signature platforms have emerged in these three years. For example, Da Fa Da, Shang Shang Qian, E Qian, Yun Qian, No.65438 +0 Qian, Yi Qian Tong, Yun Qian and so on. If you want to search, it is estimated that there are twenty or thirty.

Electronic signature is actually a form of electronic signature, which not only retains the visual effect of physical seal (that is, the appearance of seal), but also contains digital certificate to ensure that the electronic contract with electronic signature has the characteristics of identifiable signature identity and unchangeable content.

The principle of electronic signature:

We can simply understand that the digital certificate is the "electronic identity" of "I am who I am" under the network environment, and this "electronic identity" needs a special organization to manage, that is, CA organization.

When users sign contracts online with electronic signatures, CA institutions verify the authenticity and validity of the signer's identity information through a series of technical means and specific steps, and then issue digital certificates to the parties and authorize them to sign contracts. This is the process of CA authentication.

(Note: Because the interpretation of electronic signature involves many technical principles, it is not applicable to users without technical background, so I will not repeat it here for the time being. Friends in need can contact the author. )

The function of electronic signature can be embodied as follows: through the above-mentioned authentication process, after the electronic contract is signed, the parties can quickly identify the identity of the signer, the signed content and other important information by only identifying the electronic signature, thus avoiding illegal acts such as stealing, embezzling and tampering with the contract.
