+ 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>
+1> {ok, Engine} = crypto:engine_load(&lt;&lt;"otp_test_engine">>, [], []).
+ {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>
+ <p>
+ Load an engine with the help of the dynamic engine by giving the path to the library.
+ </p>
+ <code>
+ 2> {ok, Engine} = crypto:engine_load(&lt;&lt;"dynamic">>,

+ {&lt;&lt;"ID">>, &lt;&lt;"MD5">>},
+ &lt;&lt;"LOAD">>],
+ []).
+ {ok, #Ref}</code>
+ <note>
+ <p>The dynamic engine is not supported in LibreSSL from version 2.2.1</p>
+ </note>
+ </section>
+

<section>
+ <title>Feature Limitations</title>
+ <p>
+ The HiPE compiler is in general compliant with the normal BEAM compiler,
+ with respect to semantic behavior. There are however features in the BEAM compiler
+ and the runtime system that have limited or no support for HiPE compiled modules.
+ </p>
+ <taglist>
+ <tag>Stack traces</tag>
+ <item><p>Stack traces returned from <seealso marker="erts:erlang#get_stacktrace/0">
+ <c>erlang:get_stacktrace/0</c></seealso> or as part of <c>'EXIT'</c> terms
+ can look incomplete if HiPE compiled functions are involved. Typically a stack trace
+ will contain only BEAM compiled functions or only HiPE compiled functions, depending
+ on where the exception was raised.</p>
+ <p>Source code line numbers in stack traces are also not supported by HiPE compiled functions.</p>
+ </item>
+
+ <tag>Tracing</tag>
+ <item><p>Erlang call trace is not supported by HiPE. Calling
+ <seealso marker="erts:erlang#trace_pattern/3"><c>erlang:trace_pattern({M,F,A}, ...)</c></seealso>
+ does not have any effect on HiPE compiled modules.</p>
+ </item>
+
+ <tag>NIFs</tag>
+ <item><p>Modules compiled with HiPE can not call <seealso marker="erts:erlang#load_nif-2">

+ <title>Performance Limitations</title>
+ <p>
+ The HiPE compiler does in general produce faster code than the
+ BEAM compiler. There are however some situation when HiPE
+ compiled code will perform worse than BEAM code.
+ </p>
+ <taglist>
+ <tag>Mode switches</tag>
+ <item><p>Every time a process changes from executing code in a
+ HiPE compiled module to a BEAM compiled module (or vice versa),
+ it will do a mode switch. This involves a certain amount of
+ CPU overhead which can have a negative net impact if the
+ process is switching back and forth without getting enough done in
+ each mode.</p>
+ </item>
+
+ <tag>Optimization for <c>receive</c> with unique references</tag>
+ <item><p>The BEAM compiler can do an optimization when
+ a <c>receive</c> statement is <em>only</em> waiting for messages
+ containing a reference created before the receive. All messages
+ that existed in the queue when the reference was created will be
+ bypassed, as they cannot possibly contain the reference. HiPE
+ does not implement this optimization.</p>
+ <p>An example of this is when
+ <c>gen_server:call()</c> waits for the reply message.</p>
