Linux checksum

The program md5sum is designed to verify data integrity using the MD5 (Message-Digest algorithm 5) 128-bit cryptographic hash. MD5 hashes used properly can confirm both file integrity and authenticity.

It is better to do checksum if you download iso or software from untrusted source.
It is to avoid hacker added backdoor into program.
You should have your md5 hash (77969944918b0748adaa841a72db3a0):

$ cd Download
$ md5sum software.bin
$ 77969944918b0748adaa841a72db3a0 software.bin

Compare your hash result. Both must be same.
