Use OpenSSL and compare the effects of data corruption on ecb, cbc, ofb and cfb. You will create a small text file that is several blocks long, encrypt the file using DES or an AES configuration of your choice, flip a single bit in the cipher text and then decrypt the corrupted cipher text to observe the impact of the corruption on each of the above 4 modes of operation.

Discuss your observations and how they relate to the operation mechanisms of the different cipher options, ---
