CipherHUB Cryptography Toolkit

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.
