3DES Encryption

3DES Encryption algorithm implementation in Java

  • The application takes arguments from command line, the first argument is an encryption key, the second is text to be encrypted
  • If encryption key and encryption text weren't passed from the command line, the application will try reading them from environment variables ENCRYPTION_KEY TEXT_TO_ENCRYPT
  • The application uses a 24 bit encryption key and 8 bit initialization vector
  • Encryption key and initialization vector use SHA1PRNG for key generation
  • DESede/CBC/PKCS5Padding is used as transformation
  • Null values are not encrypted, if null used as an input for the encrypt method, the method will immediately return the null reference. The same applies to the decrypt method

To run the application

  • Checkout the project
  • mvn package
  • java -jar coding-0.0.1-SNAPSHOT-jar-with-dependencies.jar KEY 'text to encrypt'

To run the application via docker-compose

  • Checkout the project
  • mvn package
  • Open the docker-compose.yml and set ENCRYPTION_KEY TEXT_TO_ENCRYPT environment variables
  • docker-compose up

To run the application via docker

  • Checkout the project
  • mvn package
  • docker build -t 3des-algorithm_encryption .
  • docker run -it 3des-algorithm_encryption encryptionKey text
