+## 🔒 客户端限制功能
+
+### 功能说明
+
+客户端限制功能允许你控制每个API Key可以被哪些客户端使用，通过User-Agent识别客户端，提高API的安全性。
+
+### 使用方法
+
+1. **在创建或编辑API Key时启用客户端限制**：
+   - 勾选"启用客户端限制"
+   - 选择允许的客户端（支持多选）
+
+2. **预定义客户端**：
+   - **ClaudeCode**: 官方Claude CLI（匹配 `claude-cli/x.x.x (external, cli)` 格式）
+   - **Gemini-CLI**: Gemini命令行工具（匹配 `GeminiCLI/vx.x.x (platform; arch)` 格式）
+
+3. **调试和诊断**：
+   - 系统会在日志中记录所有请求的User-Agent
+   - 客户端验证失败时会返回403错误并记录详细信息
+   - 通过日志可以查看实际的User-Agent格式，方便配置自定义客户端
+
+### 自定义客户端配置
+
+如需添加自定义客户端，可以修改 `config/config.js` 文件：
+
+```javascript
+clientRestrictions: {
+  predefinedClients: [
+    // ... 现有客户端配置
+    {
+      id: 'my_custom_client',
+      name: 'My Custom Client',
+      description: '我的自定义客户端',
+      userAgentPattern: /^MyClient\/[\d\.]+/i
+    }
+  ]
+}
+```
+
+### 日志示例
+
+认证成功时的日志：
+```
+🔓 Authenticated request from key: 测试Key (key-id) in 5ms
+   User-Agent: "claude-cli/1.0.58 (external, cli)"
+```
+
+客户端限制检查日志：
+```
+🔍 Checking client restriction for key: key-id (测试Key)
+   User-Agent: "Mozilla/5.0 (Windows NT 10.0; Win64; x64)"
+   Allowed clients: claude_code, gemini_cli
+🚫 Client restriction failed for key: key-id (测试Key) from 127.0.0.1, User-Agent: Mozilla/5.0...

+# 升级指南 - API Key 有效期功能
+
+本指南说明如何从旧版本安全升级到支持 API Key 有效期限制的新版本。
+
+## 升级前准备
+
+### 1. 备份现有数据
+
+在升级前，强烈建议备份您的生产数据：
+
+```bash
+# 导出所有数据（包含敏感信息）
+npm run data:export -- --output=prod-backup-$(date +%Y%m%d).json
+
+# 或导出脱敏数据（用于测试环境）
+npm run data:export:sanitized -- --output=prod-backup-sanitized-$(date +%Y%m%d).json
+```
+
+### 2. 确认备份完整性
+
+检查导出的文件，确保包含所有必要的数据：
+
+```bash
+# 查看备份文件信息
+cat prod-backup-*.json | jq '.metadata'
+
+# 查看数据统计
+cat prod-backup-*.json | jq '.data | keys'
+```
+
+## 升级步骤
+
+### 1. 停止服务
+
+```bash
+# 停止 Claude Relay Service
+npm run service:stop
+
+# 或如果使用 Docker
+docker-compose down
+```
+
+### 2. 更新代码
+
+```bash
+# 拉取最新代码
+git pull origin main
+
+# 安装依赖
+npm install
+
+# 更新 Web 界面依赖
+npm run install:web
+```
+
+### 3. 运行数据迁移
+
+为现有的 API Key 设置默认 30 天有效期：
+
+```bash
+# 先进行模拟运行，查看将要修改的数据
+npm run migrate:apikey-expiry:dry
+
+# 确认无误后，执行实际迁移
+npm run migrate:apikey-expiry
+```
+
+如果您想设置不同的默认有效期：
+
+```bash
+# 设置 90 天有效期
+npm run migrate:apikey-expiry -- --days=90
+```
+
+### 4. 启动服务
+
+```bash
+# 启动服务
+npm run service:start:daemon
+
+# 或使用 Docker
+docker-compose up -d
+```
+
+### 5. 验证升级
+
+1. 登录 Web 管理界面
+2. 检查 API Key 列表，确认显示过期时间列
+3. 测试创建新的 API Key，确认可以设置过期时间
+4. 测试续期功能是否正常工作
+
+## 从生产环境导入数据（用于测试）
+
+如果您需要在测试环境中使用生产数据：
+
+### 1. 在生产环境导出数据
+
+```bash
+# 导出脱敏数据（推荐用于测试）
+npm run data:export:sanitized -- --output=prod-export.json
+
+# 或只导出特定类型的数据
+npm run data:export -- --types=apikeys,accounts --sanitize --output=prod-partial.json
+```
+
+### 2. 传输文件到测试环境
+
+使用安全的方式传输文件，如 SCP：
+
+```bash
+scp prod-export.json user@test-server:/path/to/claude-relay-service/
+```
+
+### 3. 在测试环境导入数据
+
+```bash
+# 导入数据，遇到冲突时询问
+npm run data:import -- --input=prod-export.json
+
+# 或跳过所有冲突
+npm run data:import -- --input=prod-export.json --skip-conflicts
+
+# 或强制覆盖所有数据（谨慎使用）
+npm run data:import -- --input=prod-export.json --force
+```
+
+## 回滚方案
+
+如果升级后遇到问题，可以按以下步骤回滚：
+
+### 1. 停止服务
+
+```bash
+npm run service:stop
+```
+
+### 2. 恢复代码
+
+```bash
+# 切换到之前的版本
+git checkout <previous-version-tag>
+
+# 重新安装依赖
+npm install
+```
+
+### 3. 恢复数据（如需要）
+
+```bash
+# 从备份恢复数据
+npm run data:import -- --input=prod-backup-<date>.json --force
+```
+
+### 4. 重启服务
+
+```bash
+npm run service:start:daemon
+```
+
+## 注意事项
+
+1. **数据迁移是幂等的**：迁移脚本可以安全地多次运行，已有过期时间的 API Key 不会被修改。
+
+2. **过期的 API Key 处理**：
+   - 过期的 API Key 会被自动禁用，而不是删除
+   - 管理员可以通过续期功能重新激活过期的 Key
+
+3. **定时任务**：
+   - 系统会每小时自动检查并禁用过期的 API Key
+   - 该任务在 `config.system.cleanupInterval` 中配置
+
+4. **API 兼容性**：
+   - 新增的过期时间功能完全向后兼容
+   - 现有的 API 调用不会受到影响
+
+## 常见问题
+
+### Q: 如果不想某些 API Key 过期怎么办？
+
+A: 您可以通过 Web 界面将特定 API Key 设置为"永不过期"，或在续期时选择"设为永不过期"。
+
+### Q: 迁移脚本会影响已经设置了过期时间的 API Key 吗？
+
+A: 不会。迁移脚本只会处理没有设置过期时间的 API Key。
+
+### Q: 如何批量修改 API Key 的过期时间？
+
+A: 您可以修改迁移脚本，或使用数据导出/导入工具批量处理。
+
+### Q: 导出的脱敏数据可以用于生产环境吗？
+
+A: 不建议。脱敏数据缺少关键的认证信息（如 OAuth tokens），仅适用于测试环境。
+
+## 技术支持
+
+如遇到问题，请检查：
+
+1. 服务日志：`npm run service:logs`
+2. Redis 连接：确保 Redis 服务正常运行
+3. 配置文件：检查 `.env` 和 `config/config.js`
+

+
+### 查看过期状态
+
+API Key 列表中显示：
+- 🔴 已过期（红色）
+- 🟡 即将过期（7天内，黄色）
+- 🟢 正常（绿色）
+- ♾️ 永不过期
+
+### 手动续期
+
+对于已过期的 API Keys：
+1. 点击"续期"按钮
+2. 选择新的过期时间
+3. 确认更新
+
+## 自动清理机制
+
+系统每小时自动运行清理任务：
+- 检查所有 API Keys 的过期时间
+- 将过期的 Keys 标记为禁用（`isActive = false`）
+- 不删除数据，保留历史记录
+- 记录清理日志
+
+## 测试工具
+
+### 1. 快速测试脚本
+
+```bash
+node scripts/test-apikey-expiry.js
+```
+
+创建5个测试 Keys：
+- 已过期（1天前）
+- 1小时后过期
+- 1天后过期
+- 7天后过期
+- 永不过期
+
+### 2. 迁移脚本
+
+为现有 API Keys 设置默认30天过期时间：
+
+```bash
+# 预览（不实际修改）
+npm run migrate:apikey-expiry:dry
+
+# 执行迁移
+npm run migrate:apikey-expiry
+```
+
+## 使用场景
+
+### 1. 临时访问
+
+为临时用户或测试创建短期 Key：
+```bash
+# 创建1天有效期的测试 Key
+# 在 Web 界面或 CLI 中选择"1天"
+```
+
+### 2. 定期更新
+
+为安全考虑，定期更新 Keys：
+```bash
+# 每30天自动过期，需要续期
+# 创建时选择"30天"
+```
+
+### 3. 长期合作
+
+为可信任的长期用户：
+```bash
+# 选择"365天"或"永不过期"
+```
+
+### 4. 测试过期功能
+
+快速测试过期验证：
+```bash
+# 1. 创建1小时后过期的 Key
+npm run cli keys
+# 选择修改过期时间 -> 选择测试 Key -> 1小时后
+
+# 2. 等待或手动触发清理
+# 3. 验证 API 调用被拒绝
+```
+
+## API 响应
+
+过期的 API Key 调用时返回：
+```json
+{
+  "error": "Unauthorized",
+  "message": "Invalid or inactive API key"
+}
+```
+
+## 最佳实践
+
+1. **定期审查**：定期检查即将过期的 Keys
+2. **提前通知**：在过期前通知用户续期
+3. **分级管理**：根据用户级别设置不同过期策略
+4. **测试验证**：新功能上线前充分测试过期机制
+5. **备份恢复**：使用数据导出工具备份 Key 信息
+
+## 注意事项
+
+- 过期的 Keys 不会被删除，只是禁用
+- 可以随时续期已过期的 Keys
+- 修改过期时间立即生效
+- 清理任务每小时运行一次

+# 数据导入/导出加密处理指南
+
+## 概述
+
+Claude Relay Service 使用 AES-256-CBC 加密算法来保护敏感数据。本文档详细说明了数据导入/导出工具如何处理加密和未加密的数据。
+
+## 加密机制
+
+### 加密的数据类型
+
+1. **Claude 账户**
+   - email
+   - password
+   - accessToken
+   - refreshToken
+   - claudeAiOauth (OAuth 数据)
+   - 使用 salt: `'salt'`
+
+2. **Gemini 账户**
+   - geminiOauth (OAuth 数据)
+   - accessToken
+   - refreshToken
+   - 使用 salt: `'gemini-account-salt'`
+
+### 加密格式
+
+加密后的数据格式：`{iv}:{encryptedData}`
+- `iv`: 16字节的初始化向量（hex格式）
+- `encryptedData`: 加密后的数据（hex格式）
+
+## 导出功能
+
+### 1. 解密导出（默认）
+```bash
+npm run data:export:enhanced
+# 或
+node scripts/data-transfer-enhanced.js export --decrypt=true
+```
+
+- **用途**：数据迁移到其他环境
+- **特点**：
+  - `metadata.decrypted = true`
+  - 敏感数据以明文形式导出
+  - 便于在不同加密密钥的环境间迁移
+
+### 2. 加密导出
+```bash
+npm run data:export:encrypted
+# 或
+node scripts/data-transfer-enhanced.js export --decrypt=false
+```
+
+- **用途**：备份或在相同加密密钥的环境间传输
+- **特点**：
+  - `metadata.decrypted = false`
+  - 保持数据的加密状态
+  - 必须在相同的 ENCRYPTION_KEY 环境下才能使用
+
+### 3. 脱敏导出
+```bash
+node scripts/data-transfer-enhanced.js export --sanitize
+```
+
+- **用途**：分享数据结构或调试
+- **特点**：
+  - `metadata.sanitized = true`
+  - 敏感字段被替换为 `[REDACTED]`
+  - 不能用于实际导入
+
+## 导入功能
+
+### 自动加密处理逻辑
+
+```javascript
+if (importData.metadata.decrypted && !importData.metadata.sanitized) {
+  // 数据已解密且不是脱敏的，需要重新加密
+  // 自动加密所有敏感字段
+} else {
+  // 数据已加密或是脱敏的，保持原样
+}
+```
+
+### 导入场景
+
+#### 场景 1：导入解密的数据
+- **输入**：`metadata.decrypted = true`
+- **处理**：自动加密所有敏感字段
+- **结果**：数据以加密形式存储在 Redis
+
+#### 场景 2：导入加密的数据
+- **输入**：`metadata.decrypted = false`
+- **处理**：直接存储，不做加密处理
+- **结果**：保持原有加密状态
+- **注意**：必须使用相同的 ENCRYPTION_KEY
+
+#### 场景 3：导入脱敏的数据
+- **输入**：`metadata.sanitized = true`
+- **处理**：警告并询问是否继续
+- **结果**：导入但缺少敏感数据，账户可能无法正常工作
+
+## 使用示例
+
+### 1. 跨环境迁移
+```bash
+# 在生产环境导出（解密）
+npm run data:export:enhanced -- --output=prod-data.json
+
+# 在测试环境导入（自动加密）
+npm run data:import:enhanced -- --input=prod-data.json
+```
+
+### 2. 同环境备份恢复
+```bash
+# 备份（保持加密）
+npm run data:export:encrypted -- --output=backup.json
+
+# 恢复（保持加密）
+npm run data:import:enhanced -- --input=backup.json
+```
+
+### 3. 选择性导入
+```bash
+# 跳过已存在的数据
+npm run data:import:enhanced -- --input=data.json --skip-conflicts
+
+# 强制覆盖所有数据
+npm run data:import:enhanced -- --input=data.json --force
+```
+
+## 安全建议
+
+1. **加密密钥管理**
+   - 使用强随机密钥（至少32字符）
+   - 不同环境使用不同的密钥
+   - 定期轮换密钥
+
+2. **导出文件保护**
+   - 解密的导出文件包含明文敏感数据
+   - 应立即加密存储或传输
+   - 使用后及时删除
+
+3. **权限控制**
+   - 限制导出/导入工具的访问权限
+   - 审计所有数据导出操作
+   - 使用脱敏导出进行非生产用途
+
+## 故障排除
+
+### 常见问题
+
+1. **导入后账户无法使用**
+   - 检查 ENCRYPTION_KEY 是否正确
+   - 确认不是导入了脱敏数据
+   - 验证加密字段格式是否正确
+
+2. **加密/解密失败**
+   - 确保 ENCRYPTION_KEY 长度为32字符
+   - 检查加密数据格式 `{iv}:{data}`
+   - 查看日志中的解密警告
+
+3. **数据不完整**
+   - 检查导出时是否使用了 --types 限制
+   - 确认 Redis 连接正常
+   - 验证账户前缀（claude:account: vs claude_account:）
+
+## 测试工具
+
+运行测试脚本验证加密处理：
+```bash
+node scripts/test-import-encryption.js
+```
+
+该脚本会：
+1. 创建测试导出文件（加密和解密版本）
+2. 显示加密前后的数据对比
+3. 提供测试导入命令
+4. 验证加密/解密功能

+Enhanced Data Transfer Tool for Claude Relay Service
+
+This tool handles encrypted data export/import between environments.
+
+Usage:
+  node scripts/data-transfer-enhanced.js <command> [options]
+
+Commands:
+  export    Export data from Redis to a JSON file
+  import    Import data from a JSON file to Redis
+
+Export Options:
+  --output=FILE        Output filename (default: backup-YYYY-MM-DD.json)
+  --types=TYPE,...     Data types: apikeys,accounts,admins,stats,all (default: all)
+                       stats: Include usage statistics with API keys
+  --sanitize           Remove sensitive data from export
+  --decrypt=false      Keep data encrypted (default: true - decrypt for portability)
+
+Import Options:
+  --input=FILE         Input filename (required)
+  --force              Overwrite existing data without asking
+  --skip-conflicts     Skip conflicting data without asking
+
+Important Notes:
+  - The tool automatically handles encryption/decryption during import
+  - If importing decrypted data, it will be re-encrypted automatically
+  - If importing encrypted data, it will be stored as-is
+  - Sanitized exports cannot be properly imported (missing sensitive data)
+
+Examples:
+  # Export all data with decryption (for migration)
+  node scripts/data-transfer-enhanced.js export
+
+  # Export without decrypting (for backup)
+  node scripts/data-transfer-enhanced.js export --decrypt=false
+
+  # Import data (auto-handles encryption)
+  node scripts/data-transfer-enhanced.js import --input=backup.json
+
+  # Import with force overwrite
+  node scripts/data-transfer-enhanced.js import --input=backup.json --force
