 This command is used to test the performance of cryptographic algorithms.
-To see the list of supported algorithms, use C<openssl list -digest-commands>
-or C<openssl list -cipher-commands> command. The global CSPRNG is denoted by
-the B<rand> algorithm name.

+
+The I<algorithm> can be selected only from a pre-compiled subset of things
+that the C<openssl speed> command knows about. To test any additional digest

+
+There is no way to test the speed of any additional public key algorithms

 =head1 HISTORY
 
 The B<-engine> option was deprecated in OpenSSL 3.0.
