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)

### Task 2: Encryption using Different Ciphers and Modes In this task, we will explore various encryption algorithms and modes. Utilize the `openssl enc` command to encrypt and decrypt files. For detailed information, you can access the manuals by typing `man openssl` and `man enc`. #### Command Example: ```bash $ openssl enc -ciphertype -e -in plain.txt -out cipher.bin \ -K 00112233445566778889aabbccddeeff \ -iv 0102030405060708 ``` #### Instructions: Replace the `ciphertype` with a specific cipher type, such as `-aes-128-cbc`, `-bf-cbc`, `-aes-128-cfb`, etc. You are required to try at least 3 different ciphers. To understand the command-line options and view all supported cipher types, type `man enc`. Below are some common options for the `openssl enc` command: - **-in <file>**: Specifies the input file - **-out <file>**: Specifies the output file - **-e**: Encrypts the input file - **-d**: Decrypts the input file - **-K/-iv**: Sets the key/IV in hexadecimal as the next argument - **-[pP]**: Prints the IV/key (and exits if `-P`) This task helps familiarize users with how different encryption ciphers function and how to implement them using OpenSSL.
