Return to h_comp_zlib_rnd.c CVS log

Up to [cvs.NetBSD.org] / src / tests / crypto / opencrypto

Add some trivial tests for the in-kernel opencrypto framework, and link
them into the build.  (Thanks to Matthias Drochner for the test programs!)

XXX The arc4 and null tests currently fail - under investigation.
