Install

How do I install the CipherHUB Cryptography Toolkit MCP server?

CipherHUB Cryptography Toolkit is a hosted endpoint at https://tools.cipherhub.cloud/cipherhub/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
sm9_sign ~234

[sm9_ibc] [sm9_ibc] SM9 标识签名(GM/T 0044)。签名者用 KGC 派发的用户钥签名:输入 user_private_key_in_pem(SM9ExtractKey key_kind=Sign 输出)、private_key_password(用户钥口令)、data_in_hex(消息原文 hex,签名前内部先算 SM3 摘要,流式处理,仅支持原文模式)。输出:signature_in_hex / signature_in_base64(DER 编码签名,固定 104 字节)。

xts_cipher ~494

[other] [symmetric_cipher] AES-XTS 可调窄分组模式加解密(IEEE 1619 / NIST SP 800-38E)。algorithm 可选 AES128XTS(key 32B = 数据密钥 16B + 调组密钥 16B)或 AES256XTS(key 64B = 32B + 32B)。tweak_in_hex 为 16 字节调整值,编码数据单元编号/扇区地址,密文与数据单元位置绑定。process_type 可选 Encrypt / Decrypt(两个变换不同,须显式声明)。输入 16B ~ 16MB,无填充,密文与明文等长;非 16 倍数的尾部自动走密文窃取(ciphertext stealing)。模式特点:各数据单元独立加密,支持并行与随机访问,同一数据单元加解密自同步;同一密钥下 tweak 严禁重复使用(否则两个数据单元明文相同会直接暴露相等关系);XTS 只提供保密性、可塑性攻击下无认证,需要防篡改时在外层叠加 AEAD 或签名。典型使用场景:BitLocker / LUKS2 / FileVault 全盘加密,AMD SEV-SNP 以 AES-256-XTS + VEK 加密 guest 内存(tweak 按物理地址派生,每页唯一),Intel TDX 内存加密同族。返回字段:output_data_in_hex、output_length、output_sha256、algorithm。
