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
