Opaque binary blob
open-in-new
<p>Opaque binary blob (OBB) is a term used in <a href="/facts/Telecommunications_engineering/xq79k0PW">network engineering</a> and <a href="/facts/Computer_science/lN3pEyPz">computer science</a> to refer to a sizeable piece of data, which looks like binary garbage from outside, by entities which do not know what that blob denotes or carries, but make sense to entities which have access permission and access functions to them. It is also a pejorative term for <a href="/facts/Compiler/WNfCDFJe">compiled</a> code without the source code made available (see: <a href="/facts/Binary_blob/MQPltF0B">binary blob</a>). </p>
