SlunkCrypt/frontend/src/selftest.c
LoRd_MuldeR 147d762ebc
Implemented modified and somewhat faster initialization code.
As this unavoidably breaks compatibility with pre-1.3.x versions, added a new flag to 'slunkparam_t' that enables backwards compatibility mode.
Also extended the self-test code to test the new initialization, in addition to the "legacy" initialization.
