Guidance: 1. Create a text file that is at least 1000 bytes long. 2. Encrypt the file using the AES-128 cipher; you will play around with different modes. 3. Corrupt a single bit in say the 55th byte of the cipher text. You can do this via the bless hex editor. To corrupt first bit of a byte in Bless Hex editor, Go to Tools->Bitwise Operations. Select appropriate byte and perform bitwise operations on it. For example: To corrupt first bit in "61" (hex), perform OR with "80". 4. Decrypt the corrupted cipher text file using the correct key and IV and compare with plain text to identify the loss of information. Guidance: 1.
