When you upload a file to Tenders.Net, such as a submission to an Electronic Tender Box, we will provide you with a checksum of the file.
A CheckSum (also called a hash) is a unique signature and is the result of an algorithm that converts your data into a small data block. Simply changing a single letter in your file will result in a vastly different checksum.
There are different algorithms that you can use to create this checksum, the more popular ones being MD5 and SHA-1, the latter being the one we use.
To verify the checksum that we have created you simply need to create your own SHA-1 checksum to compare against ours.
There are many programs you can use to create a SHA-1 checksum but here are 2 recommended ones:
These programs are different, but are basically the same thing: point the program to your file and it will spit out a SHA-1 hash which you then compare to the one we display on our website.
