[B<algorithm...>]
=head1 DESCRIPTION
This command is used to test the performance of cryptographic algorithms.
To see the list of supported algorithms, use the I<list --digest-commands>
-or I<list --cipher-commands> command.
+or I<list --cipher-commands> command. The global CSPRNG is denoted by
+the I<rand> algorithm name.
=head1 OPTIONS
Time the decryption instead of encryption. Affects only the EVP testing.
+=item B<-rand file...>
+
+A file or files containing random data used to seed the random number
+generator.
+Multiple files can be specified separated by an OS-dependent character.
+The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for
+all others.
+
+=item [B<-writerand file>]
+
+Writes random data to the specified I<file> upon exit.
+This can be used with a subsequent B<-rand> flag.
+
+=item B<-primes num>
+
+Generate a B<num>-prime RSA key and use it to run the benchmarks. This option
+is only effective if RSA algorithm is specified to test.
+
+=item B<-seconds num>
+
+Run benchmarks for B<num> seconds.
+
+=item B<-bytes num>
+
+Run benchmarks on B<num>-byte buffers. Affects ciphers, digests and the CSPRNG.
+
=item B<[zero or more test algorithms]>
If any options are given, B<speed> tests those algorithms, otherwise all of
