How To do SHA-1 checksum

SHA-1 is the successor of MD5 ( Read about MD5 here ) is a tool to check the integrity of your downloads.
The SHA-1 algorithm is the brainchild of the US-based National Security Agency (NSA)

Basically it works the same as the MD5, a SHA-1 file is available on the download server where you downloaded your ISOs and when opening it you will see a string of numbers that you compare to the output of the command:

CODE: $ sha1sum /home/Nikesh/downloaded.iso

The string you get from this command typically looks like:


You compare it to the string you find in the SHA-1 file on the download server. If both of them are identical you can be sure your downloaded ISO is okay and you can burn it to a CD.
