Prototype

public BlowfishCipherService() 

Source Link

Document

Creates a new CipherService instance using the Blowfish cipher algorithm with the following important cipher default attributes:

Attribute	Value
#setKeySize keySize	128 bits
#setBlockSize blockSize	64 bits (required for Blowfish )
#setMode mode	OperationMode#CBC CBC *
#setPaddingScheme paddingScheme	PaddingScheme#PKCS5 PKCS5
#setInitializationVectorSize(int) initializationVectorSize	64 bits
#setGenerateInitializationVectors(boolean) generateInitializationVectors	true **

* The OperationMode#CBC CBC operation mode is used instead of the JDK default ECB to ensure strong encryption.

    // encrypt the secret
    ByteSource encryptedSecret = cipher.encrypt(CodecSupport.toBytes(password2Encode), saltKey);
    encryptedSecretLenght = encryptedSecret.getBytes().length;

    // create a destination array that is the size of the two arrays
    byte[] destination = new byte[saltKeyLenght + encryptedSecretLenght];

    // copy ciphertext into start of destination (from pos 0, copy
    // ciphertext.length bytes)
    System.arraycopy(encryptedSecret.getBytes(), 0, destination, 0, encryptedSecretLenght);

    // copy mac into end of destination (from pos ciphertext.length, copy
    // mac.length bytes)
    System.arraycopy(saltKey, 0, destination, encryptedSecretLenght, saltKeyLenght);

    return Base64.encodeToString(destination);
