.IX Header "OPTIONS"
.IP "\fB\-engine id\fR" 4
.IX Item "-engine id"
specifying an engine (by its unique \fBid\fR string) will cause \fBspeed\fR
to attempt to obtain a functional reference to the specified engine,
thus initialising it if needed. The engine will then be set as the default
for all available algorithms.
.IP "\fB\-elapsed\fR" 4
.IX Item "-elapsed"
Measure time in real time instead of \s-1CPU\s0 time. It can be useful when testing
speed of hardware engines.
.IP "\fB\-evp algo\fR" 4
.IX Item "-evp algo"
Use the specified cipher or message digest algorithm via the \s-1EVP\s0 interface.
.IP "\fB\-decrypt\fR" 4
.IX Item "-decrypt"
Time the decryption instead of encryption. Affects only the \s-1EVP\s0 testing.
.IP "\fB[zero or more test algorithms]\fR" 4
.IX Item "[zero or more test algorithms]"
If any options are given, \fBspeed\fR tests those algorithms, otherwise all of
the above are tested.
