Once code becomes abandonware and is no longer maintained, hobbyists may want to maintain the program, add mods, or understand it better. Obfuscation makes it hard for end users to do useful things with the code.

Witryna1 mar 2002 · A mostly unnoticed paper presented to CRYPTO'01 (Santa Barbara, CA, August 19-23, 2001, LNCS vol.2139) *proved* the impossibility of efficiently obfuscating programs. It is the mathematical proof of the impossibility of a software-only DRM system on an untrusted client such as a PC. There are also a lot of … Witrynaobfuscated program is a “virtual black box.” That is, anything one can efficiently compute from the obfuscated program, one should be able to efficiently compute given just oracle access to the program. Our main result shows that it is impossible to achieve this notion of obfuscation. We prove this
