(20 points) Task 1: Encryption using Different Ciphers and Mode In this task You can use the following openssl enc command to encrypt/decrypt a file. To see the manuals, you can type man openssl and man enc. $ openssl enc \texttt{ciphertype} -e -in plain.txt -out cipher.bin \ -K 00112233445566778889aabbccddeeff \ -iv 0102030405060708 Please replace the \texttt{ciphertype} with a specific cipher type, such as -aes-128-cbc, -bf-cbc, -aes-128-cfb, etc. In this task, you should try at least 5 different ciphers. (you can choose any ciphers listed in the manuals. You can find the meaning of the command-line options and all the supported cipher types by typing \texttt{"man enc"}). You can check the contents of the output file using bless hex editor, such as $ bless cipher.bin SEERUbuntu has installed it for you. But if you are using school's VMs, you need to install bless by $ sudo apt-get install bless Lab submission: The screenshot of the 5 commands you tried and their output files. No need to submit the file and just show the result of the bless command.
