Checksum Explained

Checksums are used to verify (check) the integrity of files and identify data transmission errors, typically after copying or moving them. An MD5 checksum is a 32-character hexadecimal number that is computed on a file. If two files have the same MD5 checksum value, then there is a high probability that the two files are the same.

After the user downloads a file to their computer, they can generate an MD5 value on the same file and compare the values. There are a variety of MD5 checksum programs available on the Internet. If the checksum values differ, then there is something wrong with the downloaded file and it should be downloaded and checked again. If problems persist, contact the LANDFIRE Help Desk.

For example: an MD5 value can be generated in MS DOS using the command "CertUtil -hashfile <path><file> MD5", or in linux by using the "md5sum <path><file>" command.
