EDXOR "weighs" only about 30kB, but offers over 90 menu items including encryption functions such as Rot13, RC4 and QCypher, Bin/Hex conversion, bookmarks and various clipboard functions, as well as little gadgets like a disk-use indicator and task-killer. The look is minimalist with no buttons or graphics. EDXOR is fast, self-contained and dependency-free, handles very large files with ease and can be run from a floppy disk. It is free for private or business use; there is no paid-for version. The current version is 1.65 (2004).
In logic, "xor" stands for "exclusive or". The name of the software is presumably to be pronounced "ed-eks-or".
