RSACryptoServiceProvider.SignData中的填充方法 [英] Padding method in RSACryptoServiceProvider.SignData

问题描述

嗨.

我一直在研究在.NET Framework中使用RSACryptoServiceProvider.SignData的填充方法.我发现默认情况下它使用PKCS，但是我找不到它是PKCS#1.5，PKCS#2还是其他版本. ¿有人知道吗?最重要的是¿可以更改此功能吗?

在此先感谢

Ivan

Hi.

I have been researching about the padding method that uses RSACryptoServiceProvider.SignData in the .NET Framework. What I have found is that it uses PKCS by default but I can''t find if it is PKCS#1.5, PKCS#2 or another version. ¿Does anyone know this? And most important, ¿can this feature be changed?

Thanks in advance

Ivan

推荐答案

查看Encrypt的第二个参数.看来您只能在RSA_PADDING_PKCS1和RSA_PADDING_PKCS1_OAEP之间选择.

Look at the second parameter of Encrypt. It looks like you only have a choice between RSA_PADDING_PKCS1 and RSA_PADDING_PKCS1_OAEP.

It''s likely that the full research may require your own implementation of RSA :-(.
