Hashing Algorithms
In computer science the hash algorithms are the functions that are helpful in the
converting the contained data string in fixed length numeric string as output. Generated numeric
output string is smaller than original data of the file. The numeric strings generated using Hash
algorithms are collision-resistant. It is almost impossible to generate the same string with
different data in a file.
The MD5 algorithm operates on 512 bits at once and for this the content is padded. The
initial digest is calculated with every 512-bit message (Kale & Dhamdhere, 2018). This process
of adding the digest values are continued until the end of the content. Final digest is always 128
bit long.
The used text file and initial content is
Following is the list of the different hash values for the file with the initial content.
