RSA加密，无需填充C# [英] RSA encryption without padding C#

问题描述

我将设置场景，

我需要使用512位密钥在给定的一组字节上计算RSA加密.使用RSACryptoServiceProvider类可以轻松实现这一点，但是在计算RSA加密之前，我需要预先计算用于加密的自定义填充.

I'm required to compute RSA encryption on a given set of bytes using a 512 bit key. This can be achieved easily with the RSACryptoServiceProvider class, however I'm required to precompute custom padding for the encryption prior to computing the RSA encryption.

此自定义填充不符合RSACryptoServiceProvider的Encrypt方法中提供的PKCS#1 v1.5或v2.是否可以使用其他C#类来计算RSA加密而无需添加自己的填充?

This custom padding does not conform with the PKCS#1 v1.5 or v2 provided in the RSACryptoServiceProvider's Encrypt method. Are there any alternatives C# classes that I could use to compute the RSA Encryption without adding their own padding?

我目前正在寻找OpenSSL.Net作为替代方案，但是还有其他更好的方案/

I'm currently looking at OpenSSL.Net as an alternative, but are there others which are better/

将寻求任何帮助. 谢谢.

Any help would be appriciated. Thanks.

推荐答案

原则上，您可以使用ModPow在BigInteger上自己实现它.但这将相对较慢，并且对于私钥操作而言，它很容易计时出边信道攻击.

In principle you could implement it yourself on BigInteger using ModPow. But that will be relatively slow, and for private key operations it's wide open to timing side-channel attacks.

我相信Mono.Security(您可以在普通.net上使用它)包含支持未填充RSA的类.

I believe Mono.Security (you can use it on normal .net) contains classes that support unpadded RSA.
