It was published by State Encryption Management Bureau, China. List of specifications for OSCCA certificate and SM2 elliptic curve public key cryptography: * GM/T 0003.1-2012 * GM/T 0003.2-2012 * GM/T 0003.3-2012 * GM/T 0003.4-2012 * GM/T 0003.5-2012 * GM/T 0015-2012 * GM/T 0009-2012 IETF: https://tools.ietf.org/html/draft-shen-sm2-ecdsa-02 oscca: http://www.oscca.gov.cn/sca/xxgk/2010-12/17/content_1002386.shtml scctc: http://www.gmbz.org.cn/main/bzlb.html These patchs add the OID object identifier defined by OSCCA. The x509 certificate supports sm2-with-sm3 type certificate parsing and verification. The sm2 algorithm is based on libgcrypt's mpi implementation, and has made some additions to the kernel's original mpi library, and added the implementation of ec to better support elliptic curve-like algorithms. sm2 has good support in both openssl and gnupg projects, and sm3 and sm4 of the OSCCA algorithm family have also been implemented in the kernel. Among them, sm3 and sm4 have been well implemented in the kernel. This group of patches has newly introduced sm2. In order to implement sm2 more perfectly, I expanded the mpi library and introduced the ec implementation of the mpi library as the basic algorithm. Compared to the kernel's crypto/ecc.c, the implementation of mpi/ec.c is more complete and elegant, sm2 is implemented based on these algorithms. --- v6 changes: 1. remove mpi_sub_ui function from mpi library. 2. rebase on mainline. v5 changes: 1. fix compilation failure when SM2 is configured as a module. 2. simplify the mpi and ec code, remove unused functions reported by test robot. v4 changes: 1. Pass data directly when calculating sm2 certificate digest. 2. rebase on mainline. v3 changes: 1. integrity asymmetric digsig support sm2-with-sm3 algorithm. 2. remove unused sm2_set_priv_key(). 3. rebase on mainline. v2 changes: 1. simplify the sm2 algorithm and only retain the verify function. 2. extract the sm2 certificate code into a separate file.
