+ This chapter describes the support for loading encryption engines in the crypto application.
+ </p>
+
+ <section>
+ <title>Background</title>
+ <p>
+ OpenSSL exposes an Engine API, which makes it possible to plug in alternative
+ implementations for some or all of the cryptographic operations implemented by OpenSSL.
+ When configured appropriately, OpenSSL calls the engine's implementation of these
+ operations instead of its own.
+ </p>
+ <p>
+ Typically, OpenSSL engines provide a hardware implementation of specific cryptographic
+ operations. The hardware implementation usually offers improved performance over its
+ software-based counterpart, which is known as cryptographic acceleration.
+ </p>
+ </section>
+
+ <section>
+ <title>Use Cases</title>
+ <section>
+ <title>Dynamically load an engine from default directory</title>
+ <p>
+ If the engine is located in the OpenSSL/LibreSSL installation <c>engines</c> directory.
+ </p>
+ <code>

+ {ok, #Ref}</code>
+ <note>
+ <p>The file name requirement on the engine dynamic library can differ between SSL versions.</p>
+ </note>
+ </section>
+
+ <section>
+ <title>Load an engine with the dynamic engine</title>
