Module asymmetric

Asymmetric cryptography algorithms and key management.

非对称密码算法和密钥管理。

Overview | 概述

This module provides asymmetric (public-key) cryptographic algorithms that enable secure communication without prior key exchange. It includes both traditional algorithms and post-quantum cryptography for future security.

此模块提供非对称（公钥）密码算法，无需事先密钥交换即可实现安全通信。 它包括传统算法和后量子密码学以确保未来安全。

Algorithm Categories | 算法分类

Key Encapsulation Mechanisms (KEM) | 密钥封装机制

• RSA: Traditional public-key cryptosystem
• Kyber: Post-quantum lattice-based KEM (NIST standard)

Digital Signatures | 数字签名

• Ed25519: Edwards curve signatures (high performance)
• ECDSA P-256: NIST standard elliptic curve signatures
• Dilithium: Post-quantum lattice-based signatures (NIST standard)

Key Agreement | 密钥协商

• ECDH P-256: Elliptic Curve Diffie-Hellman

Security Considerations | 安全考虑

Traditional vs Post-Quantum | 传统 vs 后量子

• Traditional algorithms (RSA, ECDSA, ECDH): Secure against classical computers

• Post-quantum algorithms (Kyber, Dilithium): Secure against quantum computers

• 传统算法（RSA、ECDSA、ECDH）：对经典计算机安全

• 后量子算法（Kyber、Dilithium）：对量子计算机安全

Migration Strategy | 迁移策略

For long-term security, consider hybrid approaches or gradual migration to post-quantum algorithms as they become more widely adopted.

为了长期安全，考虑混合方法或随着后量子算法更广泛采用而逐步迁移。
