The role of CA certificate of Hebei State Taxation Bureau is to encrypt the data transmitted through the network, and at the same time ensure the uniqueness and non-repudiation of the declared data.

First, you need to know where your CA certificate is stored. A CA certificate usually includes five files:

EncCert.cer (encrypted certificate file)

EncPrikey.key (encrypted private key file)

Root.cer

SignCert.cer (signature certificate file)

SignPrikey.key (signature private key file)

These five files will be placed in a folder named after your tax number or company name.

The method of setting the certificate is:

1. Open Hebei national tax taxpayer information collection software, enter System Management-Parameter Settings-Security Settings, and select unified security settings for subsystems.

2. Click the browse button behind the certificate to open the corresponding file.

3. Fill in all the private key passwords with 8 digits 1.

4. Click the Save button.

5. Click the "Get Server Certificate" button.

Just return to the "online declaration" and resend the report.
