Abstract: When the law stipulates that electronic contracts should also be included in valid contracts, many commercial companies begin to draw up electronic contracts, which saves the tedious steps of mailing or delivering written contracts to parents. Because the electronic contract is displayed on the computer screen, the contract can only be proved by electronic digital signature (encryption). So, what should I pay attention to when choosing an electronic signature? Let's get to know each other. What should I pay attention to when choosing an electronic signature?

(1) Pay attention to four types of situations where electronic signatures cannot be used.

Article 3 of People's Republic of China (PRC) Electronic Signature Law: A document with electronic signature or data message agreed by the parties shall not be denied its legal effect just because it is in the form of electronic signature or data message. The provisions of the preceding paragraph shall not apply to the following documents:

1, involving personal relationships such as marriage, adoption and inheritance;

2, involving the transfer of land, housing and other real estate rights;

3, involving the cessation of water supply, heating, gas supply, power supply and other public utilities services;

4. Other circumstances in which electronic documents are not applicable as stipulated by laws and administrative regulations.

(2) Pay attention to the authenticity of the electronic signature.

1. Real identity: When electronic signature production data is used for electronic signature, it belongs exclusively to the electronic signer;

2. True will: when signing, the electronic signature production data is only controlled by the electronic signer;

3. The contract has not been changed: any change of the electronic signature after signing can be found;

4. Signature remains unchanged: any changes to the content and form of the data message after signature can be found.

(3) Pay attention to the legality of the formation and preservation of electronic signatures.

Article 4 of the Electronic Signature Law: A data message that can tangibly express its contents and can be retrieved at any time shall be regarded as a written form that meets the requirements of laws and regulations. Article 6 of the Electronic Signature Law: A data message that meets the following conditions shall be deemed to meet the document preservation requirements stipulated by laws and regulations:

1, which can effectively express the content and can be retrieved for reference at any time;

2. The format of the data message is the same as that when it was generated, sent or received, or different, but it can accurately represent the content originally generated, sent or received;

3. Be able to identify the sender and receiver of the data message and the time of sending and receiving.
