181 Use the specified cipher or message digest algorithm via the \s-1EVP\s0 interface.
182 If \fIalgo\fR is an \s-1AEAD\s0 cipher, then you can pass \fB\-aead\fR to benchmark a
183 TLS-like sequence. And if \fIalgo\fR is a multi-buffer capable cipher, e.g.
184 aes\-128\-cbc\-hmac\-sha1, then \fB\-mb\fR will time multi-buffer operation.
