4 Task 2: Encryption using Different Ciphers and Modes In this task, we will play with various encryption algorithms and modes. 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 Please replace the 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 3 different ciphers. You can find the meaning of the command-line options and all the supported cipher types by typing "man enc". We include some common options for the openssl enc command in the following: -in -out -e -d -ciphertype -e -in plain.txt -out cipher.bin \ -K 00112233445566778889aabbccddeeff \ -iv 0102030405060708 -K/-iv - [pP] input file output file encrypt decrypt key/iv in hex is the next argument print the iv/key (then exit if -P)
