Per XLS-0095, we are taking steps to rename ripple(d) to xrpl(d). This change specifically removes all copyright notices referencing Ripple, XRPLF, and certain affiliated contributors upon mutual agreement, so the notice in the LICENSE.md file applies throughout. Copyright notices referencing external contributions remain as-is. Duplicate verbiage is also removed.

The underlying implementation of this function takes pains to

attempt to outsmart the compiler from optimizing the clearing

away. Please note that, despite that, remnants of content may
|

remain floating around in memory as well as registers, caches

and more.
