Example

Please follow this example here.

AES Encryption and Decryption

• AES-256-CBC

AES aes = AES(secretKey: "datadirr", iv: "datadirr");
String encryptTxt = aes.encryptAES256CBC("Hello datadirr");
String decryptTxt = aes.decryptAES256CBC(encryptTxt);

XOR Encryption and Decryption

1. With Secret Key

• Method 1

XOR xor = XOR(secretKey: "datadirr");
String encryptTxt = xor.xorEncode("Hello datadirr");
String decryptTxt = xor.xorDecode(encryptTxt);

• Method 2

XOR xor = XOR();
String encryptTxt = xor.xorEncode("Hello datadirr", secretKey: "datadirr");
String decryptTxt = xor.xorDecode(encryptTxt, secretKey: "datadirr");

• Method 3

String encryptTxt = XOR().xorEncode("Hello datadirr", secretKey: "datadirr");
String decryptTxt = XOR().xorDecode(encryptTxt, secretKey: "datadirr");

• Method 4

String encryptTxt = XOR(secretKey: "datadirr").xorEncode("Hello datadirr");
String decryptTxt = XOR(secretKey: "datadirr").xorDecode(encryptTxt);

1. Without Secret Key

• Method 1

XOR xor = XOR();
String encryptTxt = xor.xorEncode("Hello datadirr");
String decryptTxt = xor.xorDecode(encryptTxt);

• Method 2

String encryptTxt = XOR().xorEncode("Hello datadirr");
String decryptTxt = XOR().xorDecode(encryptTxt);

JWT token decode

JWT.decode("jwt_token");
