Although .so files can still be reverse-engineered, the barrier to analyzing them is significantly higher than that of analyzing Java bytecode. Many security-related implementations rely on OpenSSL, yet tutorials on using OpenSSL within the NDK are not commonly found online. After a day of experimentation, I finally managed to invoke OpenSSL from the NDK. This article uses the HMAC algorithm in OpenSSL as an example to demonstrate how to use OpenSSL in the NDK.
I had always used ready-made TLS services and never paid much attention to the underlying details. Recently, when I needed to use RPC over TLS, I realized that understanding many concepts is necessary to use it correctly.
