Pure Implementations for encryption algorithms including DES, RSA, AES
Take AES Implementation for example
String plaintext = "passwordTextCase", key = "simpleKeyCase123";
CipherService aesService = new AESCipherService();
String encryptedText = aesService.encrypt(plaintext, key);
aesService.decrypt(encryptedText, key);For tracing the whole process of DES encryption and decryption, encryption output:
