+## [v1.0.4] - 2026-05-01
+
+### Fixed
+- **命名规范优化**：修复了多个 `WithOut` -> `Without` 的拼写错误（涉及 AES, RSA, ECDSA, Ed25519, X25519 的构造器）。
+- **接口对齐**：修复了 `NewRSAAndEraseKey` 和 `NewECDSAAndEraseKey` 遗漏 'A' 的问题。
+
+### Optimized
+- **填充性能**：使用 `bytes.Repeat` 优化 `Pkcs5Padding` 和 `AnsiX923Padding` 的执行效率。
+- **并发安全性**：通过 Benchmark 验证了高并发场景下的稳定性。

 ## 🛡️ 鲁棒性防御 (Robustness)
 - **密钥混淆**：支持超长密钥输入以混淆内存特征，内部自动适配 16/24/32 字节核心密钥。
-- **故障静默**：`DecryptBytesN` 在填充或密文损坏时静默返回原始数据，防止业务因加密错误崩溃。
-- **哈希安全**：RSA/ECDSA 签名强制默认 SHA256，防止因哈希未指定导致的空指针 Panic。
+- **命名一致性**：修复了所有 `Without` 的拼写错误，确保 API 调用链路语义严谨。
+- **填充优化**：使用 `bytes.Repeat` 替代循环填充，降低 GC 压力并提升性能稳定性。
