FlashSwirl 闪旋一款高性能的对称加密算法库提供流加密、AEAD认证加密、HASH、HMAC、HKDF、PBKDF2概述由风之暇想研究的对称加密算法基于ARXAdd-Rotate-XOR结构设计灵感来源于ChaCha20加密库提供流加密、AEAD认证加密、HASH、HMAC、HKDF密钥派生、PBKDF2密钥派生的密码学功能。✨ 特性多种加密模式支持流加密Stream和AEAD认证加密高性能设计批量处理、并行计算、内存池优化跨平台支持提供C、Go、JavaScript三种语言代码 算法规范算法规范文档 三种语言库调用说明C 版本使用示例#includeFlashSwirl.h#includeiostream#includevectorintmain(){// 准备密钥和Nonceuint8_tkey[32]{/* 32字节密钥 */};uint8_tnonce[24]{/* 24字节随机Nonce必须使用安全随机数生成 */};// 1. 流加密 std::vectoruint8_tdata{H,e,l,l,o};FlashSwirl_EncryptBuffer(key,32,nonce,24,data.data(),data.size(),20);// data现在包含密文FlashSwirl_DecryptBuffer(key,32,nonce,24,data.data(),data.size(),20);// data现在恢复为明文// 2.
