PQCP (Pioneer Quotable Crypto Provider) provides prototype implementations of post-quantum and next-generation cryptographic algorithms.

Everything in this repository is experimental:

• The code in this repository is prototype code. We make a best effort to avoid security bugs.
• Implementations may not track the latest revision of the underlying algorithm specifications. Parameters, wire formats, and security analyses may change at any time without notice, and may be incompatible across versions.
• Code here is not hardened to production grade: constant-time guarantees, side-channel countermeasures, fuzzing depth, and audit coverage are incomplete or unverified.
• Vulnerability reports against this repository — including findings from external or automated security scans and requests for explanations — should be interpreted in the above context. Such findings are welcome and will be considered on a best-effort basis; no security support commitment, service-level agreement, or backport guarantee applies to this code, and we do not guarantee acknowledgement, investigation, remediation, a timeline, or an individual response.

This code is not recommended for production systems, products, or any deployment where security matters. Use a mature, standardized, and audited implementation instead. This repository is intended only for research, evaluation, interoperability testing, and technical exploration.

PQCP（Pioneer Quotable Crypto Provider）提供后量子及新一代密码算法的原型实现。

本仓库中的一切代码均为实验性质：

• 本仓库代码均为原型实现。我们尽力避免安全问题。
• 实现未必跟进算法规范草案的最新修订版本。参数、编码格式与安全分析可能 随时变更，且各版本之间不保证兼容。
• 本仓库代码未达到生产级加固水平：常数时间保证、侧信道防护、模糊测试 深度与安全审计覆盖均不完整或未经充分验证。
• 针对本仓库的漏洞报告——包括外部或自动化安全扫描的发现及要求解释说明的 请求——应结合上述背景理解。我们欢迎相关发现并按尽力而为（best-effort） 原则评估处理；本仓库代码不适用任何安全支持承诺、服务级别协议（SLA）或 补丁回移保证，亦不保证确认收悉、调查、修复、处理时限或逐项回复。

**不推荐在生产系统、产品或安全敏感部署中使用本仓库代码。**如需使用 相关算法，请选择成熟、已标准化且经审计的实现。本仓库仅供研究、评估、互通 性测试与技术探索使用。
