$ md5sum mantaray-jdq39-factory-d79f489e.tgz b7a1162fb4e617143306ef6c4ca6c040
$ openssl sha1 mantaray-jdq39-factory-d79f489e.tgz SHA1(mantaray-jdq39-factory-d79f489e.tgz)= d79f489e1001d183b31d8a407b47cd5b8e9505cd
If it matches with the one stated at the google page, you can assume the file is not corrupted or modified.
The terminal commands only work out of the box in MacOS or Linux. To verify checksums in Windows there is a tool by Microsoft called Checksum Integrity Verifier.
