tests for libcrypto
keygen: tests public key generation and shared key generation, and 
runs iterative sign/verify tests with generated keys

sslrsa: tests rsa verify of different lengths 

certcheck: given a set of ordered cert files it loads each one and
checks them in succession. root key is hardcoded in the file. make
sure its the right one.

example: certcheck 121.cert mpc2-mftr-cert.raw mftr-CA-cert.raw 
works with the SK_REAL_ROOT

certcheck cpcert.bin cpcacert.bin 
works with player side test PKI.
