Javascript script implements static web page encryption example code_javascript skills

Javascript script implements static web page encryption. Read Javascript script to implement static web page encryption. Two days ago, I saw someone asking about static web page encryption, so I wrote this code idea: When encrypting: first encrypt the user's key A with md5 as B, then use B to XOR the source file S0 to get the target file S1, and store S1 in the js variable. When decrypting: Ask for the key, and then operate the same as encryption

I saw someone asking about static web page encryption two days ago, so I wrote this code

Things:

When encrypting: first encrypt the user's key A to B using md5, then use B to XOR the source file S0 to get the target file S1, and store S1 in the js variable.

When decrypting: Ask for the key, and then operate the same as encryption.

Because md5 is used, I personally think it cannot be cracked without a key (except for violence)

Let’s try it out haha:

The source code is as follows:

Copy code The code is as follows:
