Hello,
When I try to connect to my Windows 7 pro VM, I see the standard _welcome_ loading, but after several seconds the message changes to _logging out_ without me initiating a logout that makes it …

Hi,
I would like to use a certificate which has a brainpoolP256r1 curve, same as discussed in issue [21346](https://github.com/openssl/openssl/issues/21346). That is recommened by e.g. [BSI TR-0311…

在使用gmssl的过程中，由于开发需求，我们必须使用secp256r1椭圆曲线来开发ECC256签名和验签。我是一个初学者，主要参考了sm2_signtest.c文件。我发现简单的替换p，n，a，b等参数不能直接实现我们的需求。目前在替换一些事先define的数组，如P_PRIME和N_PRIME过程中遇到了困难。我不知道库是否中有相关部分的代码我没有找到，又或者其他曲线暂时不能在sm2_sign…

Without any change of the code, I run test_secp256r1_ecdsa and found the ecdsa result is 0 not the expected 1.
And I tried to modify msghash or sig…

Hi,
currently only secp256r1 seems to be supported among the 256-bit EC curves. Windows' certreq utility offers brainpoolp256r1 by default. Would it be much of an effort to add it to oscrypto?
