Description: Shagen is a simple utility that generates and displays SHA-1 hashes for files in a directory. Files are matched with a search spec (i.e. *.dll) and the program can optionally recurs through subdirectories.

Application 1: We created shagen as a simple way to detect intrusion on our servers. We use the utility to create a text file with SHA-1 hashes for every file in a server's system directory on a weekly basis and watch for unexpected diffs.

Application 2: Shagen can also be used in a configuration management setting to quickly ensure that the environment of non-controlled libraries and build tools match a standard.

Whenever the build environment changes, generate SHA-1 hashes for all files in the tools and library directories and check the hash lists into source control. At build time, use shagen to quickly generate hashes on the same directories and compare them to the standards. If any of the lists don't match, the build should immediately fail.

Technologies: This project demonstrates WIN32 techniques for using Memory Mapped files and the Crypto API as well as file searching and directory recursing. For more information on SHA-1 hashes visit the Wikipedia page on the subject.

Description: ExitCode is a simple Windows utility that displays the exit-code of a process. It can act as a loader when supplied with a command line, or it can attach to an existing process when supplied with a PID. In either case, the program will block until the process in question exits.

Application: We created ExitCode because we needed a quick and easy way to view the exit-codes of other programs.

Technologies: This project demonstrates techniques for creating and manipulating WIN32 Processes and threads.

Description: PETouch is a simple Windows utility that stamps a Windows executable (Portable Executable format) with a date and time. If no time is specified, the PE file is stamped with the current time.

Application: We created PETouch because we needed a way to stamp a build time on our Windows executables.

Technologies: This project demonstrates techniques for manipulating Windows PE files and using Memory Mapped Files.

Description: SyncDir is a simple utility similar to xcopy. The main difference is that it can optionally delete files and sub-directories in the target dir that do not exist in the source dir, allowing true directory synchronization.

Application: We created SyncDir as a simple way to perform backups on our in-house systems. Because it can optionally copy only changed files, it works well for incremental backups.

Technologies: This project demonstrates WIN32 techniques for file searching and directory recursing.
