SHA1files is a 32 bits console application that computes the SHA1 digest of files under Windows. The main applications are     - the detection of any change in files (typically a web server directory to make sure no file has been altered - integrity check)     - the detection of duplicate files on disk (based on their actual content, not their name or location)

NMEasync is a 32 bits console application that uses the data supplied by a GPS receiver to synchronize the date and time of a PC running Windows. The GPS receiver must generate NMEA sentences, and be connected to the PC using a serial cable. NMEAsync uses the "$GPRMC" NMEA sentence to obtain the current date and time. NMEAsync returns an errorlevel 0 if everything went OK, and a positive value otherwise. NMEAsync is freeware.
