Extract the AES-NI encrypt -> decrypt assembly conversion aes_hw_set_decrypt_key calls aes_hw_set_encrypt_key and then does a conversion, all in assembly. On x86(_64), aes_hw_set_encrypt_key internally checks OPENSSL_ia32cap_P to call one of two variants. In preparation for splitting those variants into separate functions, get the in-asm function call out o f the day by extracting an aes_hw_encrypt_key_to_decrypt_key function.

BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.
Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.
Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.
BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.
Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.
