The Encryption Methods application provides a versatile interface for testing and comparing multiple modern encryption methods. It supports AES-256 (CBC mode), AES-GCM, ChaCha20-Poly1305, and one-time pad (OTP)-style XOR encryption. Users can enter keys and plaintext to instantly encrypt and decrypt data using different algorithms, derive keys with PBKDF2, and visualize outputs in various formats. Designed as an educational and experimental tool, it helps demonstrate symmetric cryptography techniques and key handling in a simple graphical environment.
