Building and Installing OpenSSL on Windows

Fri, 21 Dec 2018 18:46:06 +0800

I recently needed OpenSSL on Windows for a challenge. I had always built it through MSYS/MinGW, which produces the static libraries libcrypto.a and libssl.a (as well as DLLs, although I generally prefer static linking). Programs compiled with GCC can use them with -lssl -lcrypto. These libraries only work with MinGW, however, and cannot be used by Visual Studio; MinGW’s Win32 API support is hardly praiseworthy either. I therefore investigated how to build OpenSSL with Visual C++.

Configuring TLS 1.3 Cipher Suites in Nginx with OpenSSL

The final TLS 1.3 specification, RFC 8446, was published in August 2018. Out of curiosity, I installed OpenSSL 1.1.1 to enable TLS 1.3 support. Recently, however, I noticed that Nginx always selected TLS_AES_256_GCM_SHA384 under TLS 1.3, regardless of the cipher-suite order in ssl_ciphers; even explicitly requesting AES-128 made no difference. This was not a serious problem, but to a would-be perfectionist it made the configuration feel incomplete.

ZJUWLAN auto connect

ZJU finally deployed WPA2 and 802.1X, so browser-based authentication is no longer necessary.

Recently, ZJUWLAN kept disconnecting for no apparent reason. The campus network required opening a browser to log in and then displayed a small “login successful” window—which i3wm tiled like an ordinary window. This was unbearable for a would-be perfectionist, so I wondered whether a script could perform the login directly and opened Chrome’s developer tools to investigate.
