Abstract
A decrypting compiler that accepts encrypted source code from a software manufacturer, decrypts the encrypted source code into plain text that is not accessible outside the compiler, and compiles the decrypted source code into linkable binary objects. Because the decrypting compiler decrypts the encrypted source code such that the plain text is not accessible outside the compiler, trade secret and proprietary information from the source code is not easily learned by third-party software developers.
