FileChecksum is a Java 1.4 application to compute common checksums for files: CRC32, MD5, SHA1, and optional SHA256 or SHA512. Checksums are small hexadecimal "signatures" for testing whether or not files have been copied correctly, such as over a network. One person sends a file along with the checksum computed on the original computer. A second person calculates a similar checksum for the received file, and if the two checksums agree, then the received file is assumed to be correct. Many web sites provide MD5 signatures for their downloads; use this program to verify files that you download.
