Tongsuo (铜锁) is an open-source cryptographic library providing modern cryptographic primitives and secure communication protocols, including Chinese commercial cryptography algorithms (SM2/SM3/SM4/ZUC), TLS 1.3, the TLCP dual-certificate protocol, post-quantum algorithms, zero-knowledge proofs, and homomorphic encryption. It is an OpenSSL-derived C library certified for Chinese commercial cryptography compliance, usable across Linux, macOS, Windows, Android, and iOS.
Use cases
- add SM2/SM3/SM4 Chinese national cryptography support to my application
- serve TLS with dual-certificate GM (TLCP) protocol
- enable RFC 8998 TLS 1.3 with Chinese cipher suites
- meet Chinese commercial cryptography compliance requirements (密评/等保)
- use post-quantum algorithms like ML-KEM and ML-DSA
- implement zero-knowledge proofs with Bulletproofs
- use homomorphic encryption like Paillier or EC-ElGamal
- replace OpenSSL with a China-compliant crypto library
When to choose
- you need Chinese national cryptography (国密) algorithm or TLCP protocol support
- you must satisfy Chinese commercial cryptography compliance and certification requirements
- you want an OpenSSL-compatible API with modern additions like ZKP, homomorphic encryption, and post-quantum crypto
- you need TLS 1.3 with RFC 8998 Chinese cipher suites or QUIC API support
When to avoid
- you only need standard international cryptography with no Chinese compliance needs — OpenSSL, BoringSSL, or rustls may be simpler
- you need a minimal footprint for embedded/IoT devices — consider the companion tongsuo-mini instead
- your stack requires language bindings or ecosystems not yet built around Tongsuo
