The digital certificate format based on SM2 crypto algorithm as specified in GM/T 0015-2012. It was published by State Encryption Management Bureau, China. The method of generating Other User Information is defined as ZA=H256(ENTLA || IDA || a || b || xG || yG || xA || yA), it also specified in https://tools.ietf.org/html/draft-shen-sm2-ecdsa-02. The x509 certificate supports SM2-with-SM3 type certificate verification. Because certificate verification requires ZA in addition to tbs data, ZA also depends on elliptic curve parameters and public key data, so you need to access tbs in sig and calculate ZA. Finally calculate the digest of the signature and complete the verification work. The calculation process of ZA is declared in specifications GM/T 0009-2012 and GM/T 0003.2-2012.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
