SM2 certificate authentication method-continuation of the Chinese-nation password algorithm

If the country has its own encryption algorithm, this article describes how to identify the certificate algorithm of sm2 ..

 

The MIIT stipulates that the oId of the signature algorithm in the SM2 certificate is 1.2.156.10197.1.501, And the oId of the public key algorithm is 1.2.840.10045. 2.1. At present, most manufacturers do not recognize these two algorithms, and the SM2 algorithm can be directly displayed in other systems.
Windows Authentication
On Windows systems, you can view the signature algorithm and Public Key Algorithm in the certificate attributes to determine whether the SM2 certificate is used. Double-click the certificate and install it in IE to view the certificate information. Currently, Windows XP 2003 Server and below do not recognize this algorithm, and the ID is displayed directly, for example, the signature algorithm and public key algorithm of the 2003 Server System are displayed.

The OS later than win7 can easily identify the ECC algorithm, and some information still cannot be fully recognized. The length displayed after the ECC algorithm is 0 bits, because it cannot be fully recognized. The Public Key algorithm displayed on Windows 7.
