+### Added
+- **统一配置解密接口 (加固版)**：新增 `OnSetDefaultAES` 与 `SetDefaultAES` 注入接口，支持自动擦除密钥与自动锁定通道。

 # Changelog: @go/crypto
 
+## [v1.1.2] - 2026-05-12
+
+### Added
+- **统一配置解密接口 (加固版)**：新增 `OnSetDefaultAES` 回调与 `SetDefaultAES` 注入接口。
+- **极致内存安全**：`SetDefaultAES` 注入生产密钥后将**自动擦除** (ZeroMemory) 传入的密钥源字节，并**自动锁定**注册通道。
+- **基础设施对齐**：同步更新 `redis`, `api`, `db`, `mail` 等项目，移除本地 `confAes`，全面接入安全加固后的 `crypto.confAES` 体系。
+
+## [v1.1.1] - 2026-05-12
+
+### Added
+- **密码学强化**：新增基于 Argon2id 的密码派生密钥 (KDF) 支持。
+- **便捷构造器**：新增 `New...ByPassword` 系列 API，支持通过密码与盐直接创建 AES (GCM/CBC)、RSA、ECDSA、Ed25519 及 X25519 实例。
+- **确定性生成**：非对称算法（ECDSA, Ed25519, X25519）支持基于密码的确定性密钥对生成，确保多端/多次调用的一致性（注：RSA 因算法特性，其确定性受 Go 版本内部实现影响）。
+- **强制内存安全**：所有 `ByPassword` 接口均强制执行 `EraseKey` 策略，派生完成后立即擦除原始密码与盐。
