## EncryptionTransformer Class

加密值转换器

```csharp
public class EncryptionTransformer : Apq.Cfg.Security.IValueTransformer
```

Inheritance [System\.Object](https://learn.microsoft.com/en-us/dotnet/api/system.object 'System\.Object') 🡒 EncryptionTransformer

Implements [Apq\.Cfg\.Security\.IValueTransformer](https://learn.microsoft.com/en-us/dotnet/api/apq.cfg.security.ivaluetransformer 'Apq\.Cfg\.Security\.IValueTransformer')

### Remarks
性能优化：
1\. 使用 Lazy 延迟编译正则表达式
2\. 使用 RegexOptions\.Compiled 提升匹配性能
3\. 使用 StringComparison\.Ordinal 进行前缀检查
4\. 简单模式使用 string\.Contains 快速路径
5\. 缓存敏感键匹配结果
