File Checksum - Compute and test CRC32, MD5, SHA1 checksums for files

FileChecksum is a Java 1.4 application to compute common checksums for files: CRC32, MD5, and SHA1. 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.

MD5 is more reliable than and preferred over the older and simpler CRC32. Many web sites will provide MD5 signatures for their downloads; you can use this program to verify files that you download.

How To Use: Unpack the archive, open a Terminal, in the opened Terminal navigate to the unpacked files and then run the app with the following command: "java FileChecksum2" (without the quotes).
