Autocad 2006 Keygen [exclusive] Request Code -

When a keygen computed an Activation Code from a Request Code, it was effectively solving a mathematical equation—often a simple XOR cipher or a known cryptographic function that had been reverse-engineered from the AutoCAD executable itself. The "Mem Patch" option present in many keygens would modify the running AutoCAD process in memory to accept the generated code, while the "Generate" button would directly compute the code.
