There seems to be some build-bug in WolfSSL, such that even though
--enable-harden (HARDEN) is default, it's not set correctly in options.h .
So we define it correctly just after parsing all other config options
BUT BEFORE we load the rest of WolfSSL headers.
These will be defined no matter what options are given to wolfssl ./configure:
ECC_TIMING_RESISTANT
TFM_TIMING_RESISTANT
Any projects which want to use Hush code from now on will need to be licensed as
GPLv3 or we will send the lawyers: https://www.softwarefreedom.org/
Notably, Komodo (KMD) is licensed as GPLv2 and is no longer compatible to receive
code changes, without causing legal issues. MIT projects, such as Zcash, also cannot pull
in changes from the Hush Full Node without permission from The Hush Developers,
which may in some circumstances grant an MIT license on a case-by-case basis.
