@Component
public class Cryptography
extends BaseCrypto

Component for cryptographic operations in the Beas Rule Engine.

This class provides encryption and decryption functionality using TripleDES algorithm. It supports field-level encryption for entities that extend CryptoState and are marked with the @Encryptable annotation.

Key features include:

• TripleDES encryption/decryption
• Field-level encryption support
• Automatic encryption state management
• Reflection-based field processing

Constructor Details

Cryptography

public Cryptography(@Value("${cryptography.key}")
 String secretKey,
 @Value("${cryptography.iv}")
 String vector)
             throws NoSuchPaddingException,
NoSuchAlgorithmException,
InvalidAlgorithmParameterException,
InvalidKeyException

Constructor that initializes the cryptographic ciphers.

This constructor initializes the encryption and decryption ciphers using the provided secret key and initialization vector. The ciphers are configured for TripleDES encryption in CBC mode with PKCS5 padding.

Parameters:

secretKey - The secret key for encryption/decryption

vector - The initialization vector

Throws:

NoSuchPaddingException - if the padding scheme is not available

NoSuchAlgorithmException - if the algorithm is not available

InvalidAlgorithmParameterException - if the parameters are invalid

InvalidKeyException - if the key is invalid

Method Details

encrypt

public void encrypt(Object source)
             throws UnsupportedEncodingException,
InvalidAlgorithmParameterException,
InvalidKeyException

Encrypts all @Encryptable fields in an object.

This method processes all fields marked with @Encryptable annotation in the given object and encrypts their values. The object must extend CryptoState for this operation to work.

Parameters:

source - The object to encrypt

Throws:

UnsupportedEncodingException - if encoding is not supported

InvalidAlgorithmParameterException - if algorithm parameters are invalid

InvalidKeyException - if the key is invalid

plainEncrypt

public String plainEncrypt(String data)
                    throws IllegalBlockSizeException,
BadPaddingException

Encrypts a plain text string.

Parameters:

data - The plain text to encrypt

Returns:

Base64 encoded encrypted string

Throws:

IllegalBlockSizeException - if the block size is invalid

BadPaddingException - if the padding is invalid

decrypt

public void decrypt(Object target)

Decrypts all @Encryptable fields in an object.

This method processes all fields marked with @Encryptable annotation in the given object and decrypts their values. The object must extend CryptoState and be in an encrypted state.

Parameters:

target - The object to decrypt

plainDecrypt

public String plainDecrypt(String data)
                    throws IllegalBlockSizeException,
BadPaddingException

Decrypts an encrypted string.

Parameters:

data - The Base64 encoded encrypted string

Returns:

The decrypted plain text

Throws:

IllegalBlockSizeException - if the block size is invalid

BadPaddingException - if the padding is invalid
