Class BytesEncryptorCoordinator

java.lang.Object

com.axelor.common.crypto.BytesEncryptorCoordinator

All Implemented Interfaces:

Encryptor<byte[],byte[]>

public class BytesEncryptorCoordinator
extends Object
implements Encryptor<byte[],byte[]>

Coordinator that routes encrypt/decrypt operations between the legacy BytesEncryptor ($AES$), BytesEncryptorPbkdf2Sha256 ($AESv1$), and BytesEncryptorPbkdf2Sha512 ($AESv2$).

All new encryptions always use the $AESv1$ format. Decryption automatically dispatches based on the version prefix embedded in the payload.

Constructor Summary

Constructors

Constructor	Description
BytesEncryptorCoordinator(OperationMode mode, String password)	Creates a coordinator with explicit modes for both the current (v1/v2) and legacy encryptors.

Method Summary

Modifier and Type	Method	Description
static BytesEncryptorCoordinator	cbc(String password)	Creates a coordinator using AES/CBC for current encryptions.
byte[]	decrypt(byte[] bytes)	Decrypts by dispatching to the appropriate bundle based on the version prefix.
byte[]	encrypt(byte[] bytes)	Always encrypts using the current $AESv1$ format.
static BytesEncryptorCoordinator	gcm(String password)	Creates a coordinator using AES/GCM for current encryptions.
boolean	isEncrypted(byte[] bytes)	Check whether the given message is already encrypted or not.
