thank you for sharing your information, your post very important for me.., Security is a very important factor, but remember the more comfortable you feel doing something then the greater the security hole, for example the car that opens the door with remote remote, we do not open the manual, if the access frequency of the car is controlled then your car disappears. In the digital world too, security with sophisticated cryptography, will also be poked up, just waiting time, therefore we must always be active on the changes in the digital world, especially the security that so quickly changed, ...., Your posts are always interesting, there is always something new, let alone the problem of equality in the digital world, I like yout post.., have a nice day... and good night @kevinwong
