Affine Cipher Encryption

This Python script performs Affine cipher encryption on a given plaintext message using user-defined values for 'a' and 'b'.

Features

• Encrypts plaintext messages using the Affine cipher with user-defined values for 'a' and 'b'.
• Supports uppercase letters.
• Preserves spaces in the input message.

Usage

1. Modify the plaintext, a, and b variables with the message and encryption parameters you want to use.

2. Run the script by executing the following command in your terminal:

python your_script_name.py

3. The script will perform the encryption and print the ciphertext.

Example

Suppose you have the following lines of code in your script:

plaintext = 'SELAMAT DATANG DI KELAS KRIPTOGRAFI'
a = 17
b = 3

After running the script, you will see the following output:

TUSXSE UXSUSR US XUFVT LXWXSUSTR
