The string is converted into a number with charCodeAt (), and then calculated, can it be cracked in reverse?

for example: after the conversion of "Hello", it should be [20320jue 22909]
if all + 10, it should be [20330j22919]
if others only get this, is it possible to reverse crack the string "Hello"?

if your information is particularly valuable, someone is willing to take the time to speculate about your algorithm, like the encryption algorithm in your topic, which is not difficult for those who especially want to crack it-- I believe that most people are not that idle, because a slightly more complex encryption process takes a long time for people who do not know the encryption process. In principle, anything that can be calculated backwards can be cracked.


the example you give is similar to classical passwords. According to an one-to-one correspondence, classical passwords can be statistically cracked (enough samples), and your encrypted content is more valuable.

and if you plan to write the encryption on the front end, it's easy to read.


if you know the encryption process or the encryption process is simple, you can crack it. This is the basic problem of encryption
