Cryptography Algorithms Implementation (Java)

Problem:

Sensitive data is often vulnerable to interception if not encrypted with secure algorithms.

Solution:

Designed and coded encryption systems (DES, AES, RSA, ElGamal) entirely from scratch. Implemented secure key generation, modular exponentiation, and full encryption/decryption workflows.

Impact:

Demonstrated how modern cryptography protects data in transit. Built a tool that can be adapted for teaching secure communication principles or testing encryption methods in controlled environments.
