Using Oracle VM Virtual Box:

To understand the properties of one-way hash functions, we would like to do the following exercise for MD5 and SHA256: Create a text file of any length. Generate the hash value H_1 for this file using a specific hash algorithm. Flip one bit of the input file. You can achieve this modification using ghex. Generate the hash value H_2 for the modified file. Please observe whether H_1 and H_2 arc similar or not. Please describe your observations in the report. You can write a short program to count how many bits are the same between H_1 and H_2.
