The CryptSums utility checksums the Mach segments of an application at compile time and inserts encrypted checksums into the binary so the application can verify at startup that it hasn't been damaged or tampered with. Once properly installed, it allows you to simply do 'make secure' to create a secure version of you application. You'll still be able to do standard 'make' and 'make debug' without interference from the checksum test. CryptSums provides a simple routine that your application can call at startup/runtime to check that the segments in memory still result in the same checksum as the file at compile time. You select which Mach segments and sections to verify. lane@sumex-aim.stanford.edu
