Editing ISAAC (cipher) (section)

== Usage outside cryptography ==

Many implementations of ISAAC are so fast that they can compete with other high speed PRNGs, even with those designed primarily for speed not for security. Only a few other generators of such high quality and speed exist in usage.{{citation needed|date=March 2023}}
ISAAC is used in the Unix tool [[shred (Unix)|shred]] to securely overwrite data.<ref>[http://git.savannah.gnu.org/cgit/coreutils.git/tree/gl/lib/rand-isaac.c GNU coreutils git]</ref>,

Also, ISAAC algorithm is implemented in Java Apache Commons Math library.<ref>{{Cite web |url=https://commons.apache.org/proper/commons-math/javadocs/api-3.4/org/apache/commons/math3/random/ISAACRandom.html |title=Apache Commons Math reference |access-date=2022-02-16 |archive-date=2022-02-16 |archive-url=https://web.archive.org/web/20220216084357/https://commons.apache.org/proper/commons-math/javadocs/api-3.4/org/apache/commons/math3/random/ISAACRandom.html |url-status=dead }}</ref>, and in [[NetHack]] for its RNG.<ref>{{Cite web |title=NetHack/src/isaac64.c at NetHack-3.7 · NetHack/NetHack |url=https://github.com/NetHack/NetHack/blob/NetHack-3.7/src/isaac64.c |access-date=2025-02-10 |website=GitHub |language=en}}</ref>
