Work with a verification assistant for different types of files in your system. Check out the options for scanning, analyzing, and confirming the current condition of elements suitable for copying and distribution. Switch between hash routines like D5, CRC32, and SHA1.
ExactFile is a file integrity verification tool. You can use it to make sure that files you copy or distribute are undamaged and unaltered. Others can use ExactFile to ensure that files you have given to them have not been damaged.
ExactFile reads a file (or group of files) and creates a checksum for each file that can be used to test the files at a later time, ensuring that they have not been altered or damaged. The checksum is a "signature" of a file created with a hash routine. A change of even one byte in a file will change its checksum value. ExactFile supports several different hash routines, including the most common (MD5, CRC32, and SHA1). Each hash method has advantages and disadvantages pertaining to computation time, checksum length, and collision potential. It is not important to understand these technical details to use ExactFile.
