thus initialising it if needed. The engine will then be set as the default
for all available algorithms.
+=item B<-elapsed>
+
+Measure time in real time instead of CPU time. It can be useful when testing
+speed of hardware engines.
+
+=item B<-evp algo>
+
+Use the specified cipher or message digest algorithm via the EVP interface.
+
+=item B<-decrypt>
+
+Time the decryption instead of encryption. Affects only the EVP testing.
