Examples

1. Put @FieldCrypto annotation on fields you want to encrypt/decrypt.

import com.max.fieldcryptor.annot.FieldCrypto;

public class Person {

    @FieldCrypto
    String name;
    String address;
    int age;
}

2. Add crypto properties to create a cipher

String cipherName = "Field-Cryptor";
CryptographicAlgorithm algorithm = CryptographicAlgorithm.AES_CBC_PKCS5_PADDING;
String key = "sampleAESKeyForDemoItIsEasyToUse";
String iv = "sampleCBCinitVec";

CipherFactory.addCipher(cipherKeyName, algorithm, key, iv, true);

3. Get the cipher from FieldCryptorFactory and encrypt / decrypt

AbstractCipher cipher = CipherFactory.getCipher(cipherKeyName);
Person person = new Person("VitaMax", "Suwon", 50);

FieldCryptor fieldCryptor = FieldCryptor.from(cipher);
Person encryptedObj = fieldCryptor.encrypt(person, Person::new);
Person decryptedObj = fieldCryptor.decrypt(encryptedObj, Person::new);

4. Check the result

System.out.println("encryptedObj = " + encryptedObj);
System.out.println("decryptedObj = " + decryptedObj);

encryptedObj = Person{name='ocWec2FvMBH7ytkZaQTbgw==', address='Suwon', age=50}

decryptedObj = Person{name='VitaMax', address='Suwon', age=50}
