ENDECRY

DRDO — Solid State Physics Laboratory

Developed ENDECRY, a cross-platform multi-format file Encryption and Decryption Application in Java, utilising AES and SHA-512 algorithms. Created an intuitive Java Swing UI and wrapped the JAR file with Launch4j for native Windows executability. Built during internship at Solid State Physics Laboratory, DRDO under the 'Security Application Development' project.
