Because NaCl modules run in a tightly controlled sandbox, they are ideal for performing client-side encryption or hashing. The plug-in can execute OpenSSL routines faster than JavaScript and more securely than a Java applet.
Unlike older technologies like ActiveX, NaCl was designed to be safe, running code in a locked-down environment where it couldn't hurt your computer. The Twist: A "Chrome-Only" World nacl-web-plug-in
In simpler terms, imagine needing to run a complex video encoder, a legacy Fortran simulation, or a low-latency trading algorithm directly from a web dashboard. Standard JavaScript would be too slow. The NaCl-Web-Plug-In bridges this gap by executing compiled native code from within the browser tab, bypassing the usual overhead of scripting languages. Because NaCl modules run in a tightly controlled
