checksum - Command line file checksum validator. checksum checks a file and returns a checksum for both md5 and sha1. To use checksum you would simply provide a file path and it will return the sum for the file. Example: checksum -f="relative\path" Example: checksum "relative\path" Example: checksum -f="c:\absolute\path" -t=sha1 You can also check against an existing signature. To validate against an existing signature (hash) you would simply provide the file and the expected signature. When checking a signature, if the signature is valid it exits with 0, otherwise it exits with a non-zero exit code. Example: checksum "c:\\path\to\somefile.exe" -c="thehash" Example: checksum -f="c:\\path\to\somefile.exe" -c="thehash" -t=sha1 SYNOPSIS checksum [-t=sha1|md5] [-c=signature] [-f=]filepath OPTIONS -?, --help, -h Prints out the options. -f, --file=VALUE REQUIRED: file - The is the name of the file. The file should exist -t, --type, --hashtype=VALUE Optional: hashtype - 'md5' or 'sha1' Defaults to 'md5'. -c, --check=VALUE Optional: check - the signature you want to check. Not case sensitive.
