Task 1: Generating Two Different Files with the Same MD5 Hash Q1. If the length of your prefix file is not multiple of 64, what is going to happen?A1. Multiple zero-paddings are being added. Q2. Create a prefix file with exactly 64 bytes, and run the collision tool again, and seewhat happens.A2. No paddings are.
Task 2: Encryption using Different Ciphers and Modes. Q1. You should try at least 3 different ciphers with ‘openssl enc’ command.A1. Typing invalid openssl commands will give valid lists of commands. Example commands given for encrypting/decrypting in the original material are as follows: By following the commands that were given, it can solve task two.
