<p>Use the specified cipher or message digest algorithm via the EVP interface. If <i>algo</i> is an AEAD cipher, then you can pass <b>-aead</b> to benchmark a TLS-like sequence. And if <i>algo</i> is a multi-buffer capable cipher, e.g. aes-128-cbc-hmac-sha1, then <b>-mb</b> will time multi-buffer operation.</p
