AES (Advanced Encryption Standard) is a symmetric block cipher standardized by NIST. It is widely used for data encryption due to its efficiency, security, and resistance to cryptographic attacks.
AES works on fixed block sizes of 128 bits and supports key sizes of 128, 192, or 256 bits. It uses multiple rounds of substitution, permutation, mixing, and key addition.
- Key generation (128/192/256-bit support)
- AES Encryption and Decryption in ECB/CBC mode
- Padding handling for plaintext blocks
- CLI-based user interaction
- Handles both text and file encryption/decryption
- Technical documentation and output visualization
git clone https://github.com/your-username/AES-Project.git
cd AES-Projectpython Code/AES_CS22B1028_Implementation.pyYou will be prompted to enter a plaintext message or file to encrypt and will see encrypted and decrypted results.
A comprehensive explanation of the AES algorithm is available in the Report/AES_CS22B1028_Report.pdf. It covers:
- Overview
- Block cipher design and round structure
- Methodology
- Applications
- Conclusion
An example result of AES encryption is available in the Result/AES_CS22B1028_Result.png file.
