JWT身份认证通过JWT实现用户身份验证的核心代码片段cdf::JWTAuthServer jwtServer; cdf::CDFDistAuthServerOptions options; options.algType CryptoHmacAlg::HMAC_SHA256; options.tokenExpireMinutes 480; options.execPath /usr/bin/bao; options.accessToken your_bao_token; options.domainId 0; jwtServer.Start(options); // 设置加密密钥 jwtServer.SetEncryptionKey(your_secure_key); // 生成令牌 std::string input userexample.com; std::vectorchar token(tokenLen); CDFDistAuthCreateTokenOptions tokenOptions{input.c_str(), input.length() 1, token.data(), tokenLen}; auto result jwtServer-CreateToken(tokenOptions); // 验证令牌 cdf::CDFDistAuthValidateTokenOptions validateOptions{token.c_str(), token.length() 1}; jwtServer.ValidateToken(validateOptions);4. Kerberos双向认证配置Kerberos环境并实现客户端-服务端双向认证// 服务端初始化 cdf::KrbServer server; server.GetKerberosKeytab(./example.keytab, keytable, keytableLen, false); server.ServerInit(serverEXAMPLE.COM, {keytable, keytableLen}); // 客户端初始化 cdf::KrbClient client; client.ClientInit(userEXAMPLE.COM, serverEXAMPLE.COM, {keytable, keytableLen}); // 获取并验证凭证 auto [ret, cred] client.ClientGetCred(0); server.ServerAuth(0, serverInCred, serverCredOut, serverCredLenOut); client.ClientAuthServer(0, serverCredOut, serverCredLenOut); 进阶应用与最佳实践白名单授权控制通过配置JSON格式的白名单实现权限管理auto authorizor WhitelistAuthorization(); rapidjson::Document document; // 构建白名单配置 document.SetArray(); rapidjson::Value user1(rapidjson::kObjectType); user1.AddMember(user, user1, document.GetAllocator()); user1.AddMember(allow, rapidjson::kTrueType, document.GetAllocator()); document.PushBack(user1, document.GetAllocator()); // 初始化并校验权限 authorizor.Initialize(conf); authorizor.CheckPermission(user1, xx, xx);PSK密钥生命周期管理实现PSK密钥的生成、更新和删除cdf::PsKManagerInitOptions options; options.algType cdf::CryptoSymAlg::AES256_GCM; options.exePath /usr/bin/bao; options.accessToken your_token; options.domainId 0; auto pskMgr cdf::PskManager::GetInstance(); pskMgr.Init(options); // 生成PSK cdf::PskParam pskParam{Huawei, Subject, 256, 30, std::time(nullptr)}; cdf::Psk outputPsk; pskMgr.GeneratePsk(pskParam, outputPsk); // 更新和删除PSK cdf::Psk updatePsk; pskMgr.UpdatePsk(outputPsk.GetPskId(), outputPsk.GetPskContent(), updatePsk); pskMgr.DeletePsk(outputPsk.GetPskId()); 相关资源详细接口说明docs/api_documentation.md完整使用指南docs/usage_guidelines.md测试案例参考test/通过本指南你已经掌握了cdf-crypto的基本安装配置和核心功能使用。如需深入了解某个模块可以参考上述资源或查看对应源代码实现。【免费下载链接】cdf-cryptoA lib that provides a programming framework for high-strength cryptographic algorithms and key security.项目地址: https://gitcode.com/openeuler/cdf-crypto创作声明：本文部分内容由AI辅助生成（AIGC），仅供参考
