Code Review and Enhancements for Cipher Implementations

[smog-root]

I would like to request a code review and suggestions for enhancements on the following cipher implementations in you'r project:

I'm expecting a gssoc-ext with level label. @UTSAVS26

1. Affine Cipher (affine_cipher.py):

• Currently implements encryption and decryption using the Affine cipher.

• Potential Improvements:

• Validate that the 'a' parameter is coprime with 26.

• Consider supporting lowercase characters without losing case sensitivity.

2. Caesar Cipher (caesar_cipher.py):

• Implements a Caesar cipher with encryption, decryption, and brute-force decryption functionality.

Potential Improvements:

• Add handling for non-string inputs in the encrypt and decrypt methods.
• Consider modularizing the class structure to facilitate state management.

3. Playfair Cipher (playfair_cipher.py):

• Implements Playfair cipher encryption and decryption with key table generation and text preprocessing.

• Potential Improvements:

• Add error handling for non-alphabetic characters during text preprocessing.

• Consider encapsulating the functionality within a class for better organization and state management.
