GmSSL is an open-source cryptographic toolkit developed at Peking University implementing Chinese national commercial cryptography standards (SM2/SM3/SM4/SM9/ZUC), X.509 certificates, and SSL/TLS protocols including TLCP and TLS 1.3 with SM cipher suites. It is an OpenSSL-compatible C library with a command-line tool, multi-language bindings (Java, Go, PHP, Python, Rust), and support for Chinese cryptographic hardware via SKF/SDF interfaces.
Use cases
- implement SM2/SM3/SM4/SM9 national cryptography algorithms in C applications
- build TLS/TLCP servers with Chinese SM cipher suites
- generate and sign SM2 X.509 certificates for a PKI/CA
- encrypt and decrypt files with SM4 from the command line
- integrate Chinese crypto hardware keys and PCIe cipher cards via SKF/SDF engines
- add SM cryptography to Java, Go, PHP, Python, or Rust applications
- embed lightweight national crypto algorithms in embedded MCU firmware
- comply with Chinese commercial cryptography compliance requirements
When to choose
- you need Chinese national cryptography (SM) algorithm support with regulatory compliance
- you want an OpenSSL-compatible library that supports TLCP and TLS 1.3 SM cipher suites
- you need to integrate Chinese cryptographic hardware (USB keys, PCIe cipher cards)
- you need a lightweight crypto library for embedded or resource-constrained environments
- you need multi-language bindings for SM algorithms
When to avoid
- you only need standard international algorithms like AES/RSA with no SM requirements
- you need a pure high-level language implementation without C dependencies
- your project requires FIPS-validated or internationally certified crypto modules
- you need broad algorithm coverage beyond SM and mainstream international ciphers
