Cryptographic Program

Java Implementation of symmetric & asymmetric cryptographic program such as encryption, decryption, signature verification, hash.

Tasks

• AES encryption/decryption with two key lengths, 128 and 256 bits, and two modes ECB and CBC
• RSA encryption and decryption
• RSA Signature
• SHA-256 hashing

Prerequisites

You need to install these softwares to run the project.

• Java 8 version or latest
• Any smart ide like Intellij IDEA, Eclipse or Android Studio

How to run

• First of all change the path from Main.java where you want to save the keys and signature otherwise you will get exception.
• Only run Main.java and give the inputs. Thus all the tasks will be executed.
• You can comment/uncomment specific tasks to run specific task in Main.java.
• Check Execution time of each algorithm in console after running. (Values in microsecond)
