Problems solved by technology

It can be seen that the existing method needs to manually go to the website of the relevant SSL certificate issuer to obtain the corresponding intermediate certificate. The intermediate certificates used by different certificate authorities and different certificate types may be different, and batch and automatic acquisition cannot be achieved.

Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] The SSL certificate chain automatic completion method of the present invention realizes the judgment and automatic conversion of the certificate file format, the verification of the validity and integrity of the certificate, the judgment of the model of the certificate, the matching of the intermediate certificate, and the output of the complete certificate chain file. Specifically include the following steps:

[0028] 1. Verify the integrity of the input certificate, and parse the certificate through the OpenSSL tool. The certificate that cannot be parsed correctly is an incomplete certificate or a wrong certificate. The certificate that can be parsed correctly can obtain the complete content of the certificate, including the common name of the certificate, issuer, validity period and other information; if the certificate is w...

Abstract

The invention discloses a method for automatically completing an SSL certificate chain, which comprises the following steps: verifying the integrity of the input certificate; judging the encoding format of the input certificate, and if the format of the certificate is in the DER format, converting the certificate in the DER format into Certificate in PEM format; obtain the validity period of the certificate according to the parsed certificate content; obtain the issuer information and common name information of the certificate according to the parsed certificate content, and compare whether the issuer information is consistent with the common name information; the issuer information and common name information When the information is inconsistent, add this certificate to the certificate chain file; match the common name information in the certificate library with the certificate with this issuer information according to the issuer information of this certificate; judge the issuer information and common name information again for the matched certificate , until the issuer of the certificate is consistent with the common name, and the process ends. The invention automatically completes certificate files in batches, omitting the work of manually verifying certificate integrity, certificate encoding format and certificate chain.

Description

technical field [0001] The invention relates to the field of SSL certificates, in particular to a method for automatically completing an SSL certificate chain. Background technique [0002] The SSL certificate establishes an SSL security channel between the client browser and the Web server, through which the SSL protocol can be activated, and the encrypted transmission of data information between the client and the server can be realized, which can prevent the leakage of data information and ensure the security of both parties. The security of passing information, and the user can verify whether the website it visits is authentic and reliable through the server certificate. [0003] If a website wants to use the HTTPS protocol, a trusted digital certificate authority needs to issue an SSL digital certificate. It needs to apply for a certificate from the certificate authority. After the issuer verifies the identity of the server, it will issue a digital certificate correspon...
