Abstract
Techniques used in coding software are described. An encoder encodes a machine executable program or portions of a machine executable program. The encoding process uses a cipher table, a unique key for encoding, and an agreement between the encoder and decoder as to what portions of a machine executable will be encoded. By using the decoder on a computer system which may execute the encoded machine executable, the decoder may serve as a recognizer to only execute those machine executable programs which have been encoded and are recognized by the recognizer. If a machine executable is not recognized or rejected, appropriate actions may be taken other than the machine executable.
