Class CryptoEnginesFactories

java.lang.Object

cz.d1x.dxcrypto.encryption.crypto.CryptoEnginesFactories

All Implemented Interfaces:

EncryptionEnginesFactories

public class CryptoEnginesFactories
extends Object
implements EncryptionEnginesFactories

Factories for engines that use Java standard API (javax.crypto) as encryption implementations. This factory creates these algorithms:

• AES-128: CBC mode with PKCS#5 padding and PBKDF2 with HMAC-SHA1 for key derivation
• AES-256: CBC mode with PKCS#5 padding and PBKDF2 with HMAC-SHA1 for key derivation
• 3DES: CBC mode with PKCS#5 padding and PBKDF2 with HMAC-SHA1 for key derivation
• RSA: ECB mode with OAEP SHA-256 and MGF1 padding

Note that if you use AES-256 and stronger ciphers, JCE installation is required for this factory. You can check whether it is installed by isJceInstalled().

Method Detail

aes

public SymmetricEncryptionEngineFactory aes()

Description copied from interface: EncryptionEnginesFactories

Creates a new engine factory for AES (128 bits).

Specified by:

aes in interface EncryptionEnginesFactories

Returns:

factory for AES

aes256

public SymmetricEncryptionEngineFactory aes256()

Description copied from interface: EncryptionEnginesFactories

Creates a new engine factory for AES (256 bits).

Specified by:

aes256 in interface EncryptionEnginesFactories

Returns:

factory for AES-256

tripleDes

public SymmetricEncryptionEngineFactory tripleDes()

Description copied from interface: EncryptionEnginesFactories

Creates a new engine factory for Triple DES.

Specified by:

tripleDes in interface EncryptionEnginesFactories

Returns:

factory for Triple DES

rsa

public RSACryptoEngineFactory rsa()

Description copied from interface: EncryptionEnginesFactories

Creates a new engine factory for RSA.

Specified by:

rsa in interface EncryptionEnginesFactories

Returns:

factory for RSA

isJceInstalled

public static boolean isJceInstalled()

Checks whether Java Cryptography Extension (JCE) is installed. Thus stronger ciphers (e.g. AES-256 can be used).

Returns:

true if JCE is installed, otherwise false
