Make a digital signature:
1, and found a national certified CA digital certification institution.
2. Apply for a digital certificate, including off-line direct authentication and identification, and make corresponding data and distribute it to digital signature holders (all acts of collecting certificates on their behalf will lead to the invalidity of certificates).
3. You can use digital signature in electronic documents by using your own digital signature certificate and plugging it into the USB interface of the computer.
Frequently asked questions about using digital signature:
1. The most common thing is that digital certificates are lost or stolen, which leads to the signing of some electronic documents/contracts. It is difficult to prove the legitimacy of these documents and to obtain judicial support.
2. Issue of digital certificates. At present, many CA digital certificates have not been issued to signers, or have been collected by other companies. This situation will invalidate the certificate because the signer is not the only holder of the digital certificate.
3. The digital certificate will be invalid and cannot be used. You need to apply again!
