The signature of the business license is confidential and will not be made public, so it cannot be inquired. When an enterprise submits an application and an electronic signature, it needs to go to industrial and commercial registration, where the enterprise belongs, register online for the whole process, download and install the driver of the digital certificate authority, then insert the digital certificate, open the certificate client, click on the signature in the electronic signature application form, select the required corresponding certificate to complete the signature, and then enter the declaration system. The signer can sign electronically at one time. Please note that all signers need to complete their electronic signatures on the same electronic application form before entering the next electronic application form.

Based on cryptography, "electronic signature" is authenticated and calculated by a set of parameters and rules, so that the identity of the signer and the integrity of data can be verified. "Electronic signature" requires a third-party electronic certification service provider, that is, CA certification authority to issue a digital certificate. Based on conventional cryptography and other cryptographic algorithms, this electronic signature generates a series of symbols and codes instead of handwritten signatures, which can ensure the integrity, confidentiality and non-repudiation of data.
