com.ksyun.ks3.service.encryption.internal.CipherFactory

public class CipherFactory
extends Object

Factory for creating Ciphers based on the crypto key and configuration specified in the constructor. Each invocation of createCipher() will produce a new, identical Cipher object. Each returned Cipher will encrypt data with exactly the same output as any other Cipher returned by this instance of CipherFactory.

CipherFactory

public CipherFactory(SecretKey symmetricKey,
             int cipherMode,
             byte[] initVectorBytes,
             Provider cryptoProvider)

Creates a new CipherFactory that will produce ciphers using the specified key, mode, IV and provider.

参数:

symmetricKey - The symmetric key used in the ciphers created by this factory.

cipherMode - The mode indicating whether the created ciphers are for encrypting or decrypting.

initVectorBytes - The optional crypto IV used to initialize the ciphers.

cryptoProvider - The optional Java crypto provider implementation, if an alternate crypto provider is to be used.

方法详细资料

createCipher

public Cipher createCipher()

Creates a new Cipher instance based on the crypto parameters specified in the constructor. Each Cipher instance is identical to any other Cipher produced by this CipherFactory.

返回:

A new Cipher instance, identical to each Cipher produced by this factory instance.

getCryptoProvider

public Provider getCryptoProvider()

getCipherMode

public int getCipherMode()

getIV

public byte[] getIV()
