CipherHUB MCP Server

MCP License Tools

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)
