Question

I have a trouble about pyopenssl. The error message is 'OpenSSL.SSL.WantReadError'.

I'm debugging below. https://github.com/opencv/open_model_zoo

First error happened. asn1crypto._ffi.LibraryNotFoundError: The library libcrypto could not be found

I confirmed info below.

where to get and install crypto.dll on 64 bit Windows

I changed from crypto to libcrypto in the file.

(virtualenv path)\\Lib\\site-packages\\asn1crypto_perf_big_num_ctypes.py

So I resolved the first error. But Second error happend.

OpenSSL.SSL.WantReadError

My environment is below. Windows 10 virtualenv Python 3.7.1 pyopenssl 19.0.0 Visual C++ 2017 OpenSSL 1.0.2、1.1.0、1.1.1

(virtualenv path)\\Lib\\site-packages\\OpenSSL\\SSL.py

error = _lib.SSL_get_error(ssl, result)
if error == _lib.SSL_ERROR_WANT_READ:
    raise WantReadError()
I installed OpenSSL both of 1.0.2 and 1.1.1.

The error message is 'OpenSSL.SSL.WantReadError'.
