Summary
This is a production cryptography toolkit that exposes 31 operations over streamable HTTP, from classical algorithms like AES and RSA to post-quantum schemes including ML-KEM and ML-DSA. It covers Chinese national standards (SM2, SM3, SM4, ZUC) and has certified interoperability with AWS KMS and Tencent Cloud KMS. You get hash functions, symmetric and asymmetric encryption, digital signatures, ECDH key exchange, and hybrid X25519+ML-KEM-768 key encapsulation. Reach for this when you need Claude to perform cryptographic operations without rolling your own implementations, or when working across classical and post-quantum cryptography in the same workflow. All tools are stateless JSON-RPC calls.

CipherHUB MCP Server
Production-grade cryptography toolkit exposing 31 cryptographic operations via MCP (Model Context Protocol).
Overview
CipherHUB is a cryptography toolkit that enables AI agents to perform cryptographic operations without implementing algorithms themselves. It covers:
- Classical Algorithms: AES, RSA, ECC (SECP256R1/384R1/521R1, X25519, Ed25519)
- Chinese National Standards: SM2, SM3, SM4, ZUC
- Post-Quantum Cryptography: ML-KEM (FIPS 203), ML-DSA (FIPS 204), X25519+ML-KEM-768 Hybrid KEX
- Interoperability: Certified with AWS KMS (64/64) and Tencent Cloud KMS (39/39)
