.NET支持AES OFB [英] Does .NET support of AES OFB

问题描述

.NET有一个支持AES OFB加密的类？

我试图使用AesCryptoServiceProvider，但是当我将模式设置为CipherMode.OFB时，我得到了例外：指定的算法无效

AesManaged不允许反馈模式（基于MSDN文档）

解决方案

基本对称算法类仅支持CBC& CFB。

这可以被覆盖，但在AesCryptoServiceProvider类中没有这样做。也许第三方图书馆可能会实施这些密码模式。

*澄清：[我在看着.net v3.5]

Does .NET has a class that supports AES OFB encryption?

I've tried to use AesCryptoServiceProvider but when I set the Mode to CipherMode.OFB I got an exception: Invalid algorithm specified

AesManaged doesn't allow feedback modes (based on the MSDN documentation)

解决方案

The base SymmetricAlgorithm class only supports CipherModes of CBC & CFB.

This can be overridden, but is not done so in the AesCryptoServiceProvider class. Perhaps a 3rd party library may implement these Cipher Modes.

*Clarification: [I was looking at .Net v3.5]
