dotnet 6 在 win7 系统 AES CFB 抛出不支持异常
本文记录在 win7 系统上调用 AES 加密时，采用 CFB 模式，可能抛出 CryptographicException 异常
可以看到抛出的异常提示是 System.Security.Cryptography.CryptographicException: The current platform does not support the specified feedback size. 异常堆栈如下
System.Security.Cryptography.CryptographicException: The current platform does not support the specified feedback size.
---> Internal.Cryptography.CryptoThrowHelper+WindowsCryptographicException: Unknown error (0xc10000bb)

at Internal.Cryptography.AesImplementation.CreateDecryptor(Byte[] rgbKey, Byte[] rgbIV)
这个异常抛出的原因是在 https://github.com/dotnet/runtime/issues/42214 里有大佬提到这个问题，在 https://github.com/dotnet/runtime/pull/42261 里进行了修改代码，核心修改大概如下
private static Lazy<SafeAlgorithmHandle> Open3DesAlgorithm(string cipherMode, int feedback = 0)
{
return new Lazy<SafeAlgorithmHandle>(() =>
{
SafeAlgorithmHandle hAlg = Cng.BCryptOpenAlgorithmProvider(Cng.BCRYPT_3DES_ALGORITHM, null,
Cng.OpenAlgorithmProviderFlags.NONE);
hAlg.SetCipherMode(cipherMode);
// The default feedback size is 1 (CFB8) on Windows. Do not set the CNG property
// if we would be setting it to the default. Windows 7 only supports CFB8 and
// does not permit setting the feedback size, so we don't call the property
// setter at all in that case.
if (feedback > 0 && feedback != 1)
{
try
{
hAlg.SetFeedbackSize(feedback);
}
catch (CryptographicException ex)
{
throw new CryptographicException(SR.Cryptography_FeedbackSizeNotSupported, ex);
}
}
return hAlg;
});
}
本质的问题在于 win7 不支持
那为什么之前的 .NET Framework 在 win7 能正常工作？这是因为在 .NET Framework 里面有完全托管的实现，而不是和 .NET 6 一样调用系统层
可选的修复方法就是从 .NET Framework 拷贝一份，以下是我拷贝的代码
