question: public static byte [ ] decryptKey ( byte [ ] password , byte [ ] encryptedKey ) { try { Cipher c = Cipher . getInstance ( ENCRYPT_KEY_ALGORITHM ) ; c . init ( Cipher . DECRYPT_MODE , new SecretKeySpec ( password , SECRET_KEY_ALGORITHM ) , CBC_SALT_KEY ) ; return c . doFinal ( encryptedKey ) ; } catch ( Exception e ) { throw new IllegalStateException ( ENCRYPT_KEY_ALGORITHM + " is not available" , e ) ; } }
target:  Decrypt key (does not use salting, so the encryption result is the same for the same input)
