Complete Kerberos protocol implementation with hybrid RSA 2048-bit/AES 256-bit encryption. Features Key Distribution Center (AS + TGS), ticket-based SSO, mutual client-server authentication, session key generation, JavaFX GUI, CSV user database, comprehensive logging, and 5-minute ticket expiration. Educational Active Directory clone.

Flask web authentication portal with two-factor authentication using 100-iteration SHA-256 hash chain-based OTP, RSA-encrypted database storage (PKCS1_OAEP), secure password hashing, automatic OTP chain renewal, and session management. Educational Python web security project demonstrating modern authentication.

Classical cryptography toolkit with cipher implementations (Caesar, Affine, Monoalphabetic) and automated cryptanalysis using brute force attacks and statistical frequency analysis for breaking encryption.

Enterprise file integrity monitoring system using RSA digital signatures, X.509 certificates, and cryptographic hashing (MD5/SHA-256). Features AES encryption, tamper detection, and audit logging.

Includes projects done in "BBM203: Data structures lab" course.
