JVX security level

JVX file adopts 256bit "runlength" coding techniques. At present, the most effective way to crack this technique is called reverse engineering. That is, it must employ disassembler to track pass point and encryption mask. It is a fact that each file collects totally different pass point and encryption mask under "runlength" coding techniques. The rate of same mask appearance is 2 to the power of 256, about 1.1579 * 10⁷⁷ kinds of combinations. The repetition rate is almost zero. So even you adopt reverse engineering and there is no way to crack the file. Let us think in worst way, in case some strangers get your private images one day, they absolutely can not view them without your password.
