Created attachment 399936 [details] log_x64_build Environment: VS 2019 + Windows Server 2016 Issue description: We tried to build WebKit using VS2019 on Windows Server 2016. WebKit failed to build due to (error C3861: 'EVP_aes_128_wrap': identifier not found) and (error C2065: 'EVP_CIPHER_CTX_FLAG_WRAP_ALLOW': undeclared identifier) on windows with MSVC. It can be reproduced on master branch latest commit f8ae026. Could you please help take a look at this? Thanks in advance!
