Why do I have this feeling of deja-vu...
* Need to ensure that NSS is initialized before calling
* ike_alg_init(). Sanity checks and algorithm testing
* require a working NSS.
* When testing the algorithms in FIPS mode (i.e., executing
* crypto code) NSS needs to be pointed at a real FIPS mode
* NSS directory.
