FileChecksum is software that calculates CRC32, MD5, and SHA1 checksums for files using Java 1.4.
FileChecksum is especially convenient when sending a file from one person to another. During file transfer, the original sender computes the checksum of the file being sent. Then, the person receiving the file will calculate a similar checksum for the received file. If both checksums are the same, the file is considered to be accurate.
The MD5 checksum is regarded as more reliable than older CRC32 as it is more sophisticated. A lot of websites use MD5 signatures for their downloads. This software, FileChecksum, is ideal for verifying downloaded files.
