# Crypto Engine
## 模块介绍
CE 模块主要支持对称算法、非对称算法、摘要算法进行数据的加密和解密功能。
CE 模块主要支持的算法如下：
- AES 算法 ECB/CBC/CTR/CTS/OFB/CFB/CBC-MAC/XTS 等模式.
- HASH 算法 MD5/SHA1/SHA224/SHA256/SHA384/SHA512/HMAC-SHA1/HMAC-SHA256.
- 非对称算法 RSA512/1024/2048/3072/4096.
## 模块配置
其menuconfig 的配置如下：
```shell
Kernel Setup --->
Drivers Setup --->
SoC HAL Drivers --->
CE devices --->
[*] enable ce driver
[*] enbale ce hal APIs Test command
```
## 源码结构
