Introduction to JS obfuscation and encryption, and simple code examples

JS obfuscation encryption is a commonly used security encryption technology, which can convert JavaScript code into a form that is difficult to understand and crack, thereby protecting the security of the code.

1. Convert a string to a number:

function encryptString(str) {
    
      
  return str.replace(/[^a-zA-Z0-9]/g, function(c) {
    
      
    return Math.floor(Math.random() * 26) + c.charCodeAt(0);  
  });  
}  
  
const encryptedStr = encryptString("Hello, World!");  
console.log(encryptedStr);

2. Convert numbers to strings:

function decryptString(str) {
    
      
  return str.replace(/[^a-zA-Z0-9]/g, function(c) {
    
      
    return c.charCodeAt(0) - Math.floor(Math.random() * 26);  
  });  
}  
  
const decryptedStr = decryptString("Khoor, Zruog!");  
console.log(decryptedStr);

3. Convert a string to a number:

function encryptNumber(str) {
    
      
  return str.replace(/[^a-zA-Z0-9]/g, function(c) {
    
      
    return Math.floor(Math.random() * Math.pow(26, Math.floor(Math.random() * 26))) + c.charCodeAt(0);  
  });  
}  
  
const encryptedNumber = encryptNumber("12345");  
console.log(encryptedNumber);

4. Convert numbers to strings:

function decryptNumber(str) {
    
      
  return str.replace(/[^a-zA-Z0-9]/g, function(c) {
    
      
    return c.charCodeAt(0) - Math.floor(Math.random() * Math.pow(26, Math.floor(Math.random() * 26)));  
  });  
}  
  
const decryptedNumber = decryptNumber("Khoor, Zruog!");  
console.log(decryptedNumber);

5. Summary

In addition to encryption, there are some other application scenarios and advantages, such as:

1. Protect the security of the code:
         Using JS obfuscation encryption technology can convert the code into a form that is difficult to understand and crack, thereby protecting the security of the code.
2. Protect the privacy of data:
         Using JS obfuscation encryption technology can convert the code into a form that is difficult to understand and crack, thereby protecting the privacy of data.
3. Improve code readability and maintainability:
         Using JS obfuscation encryption technology can convert code into a form that is difficult to understand and crack, thereby improving code readability and maintainability.
4. Accelerate the running speed of the code:
         Using JS obfuscation encryption technology can convert the code into a form that is difficult to understand and crack, thereby speeding up the running speed of the code.

In short, JS obfuscation encryption technology is a very practical security encryption technology that can be widely used in various scenarios and applications. Finally, I recommend an online tool specially used for JS obfuscation and encryption . If you are interested, you can try it, and it may be helpful to you.
