What is code obfuscation?
Code obfuscation is the act of converting a computer program's code into a form that is functionally equivalent, but difficult to read and understand. Obfuscated code is difficult to decompile, and even if decompilation is successful, it is difficult to derive the true semantics of the program. This technology can effectively improve the difficulty of applications being reverse-engineered.
Code obfuscation methods
1.Character replacement
ll characters in the code are replaced, making the code more difficult to understand and crack. For example, replace "<" with "<", replace ">" with ">", replace "=" with "=", etc. Doing so can make the code more secure, but it also increases the length and complexity of the code.
2. Code compression
lFront-end code obfuscation skills. By removing useless characters such as spaces, newlines, and comments in the code, the code is made more compact and concise. Doing this can reduce the size of the code and improve page loading speed, but it will also make the code more difficult to understand and modify.
3. Code encryption
ll code is encrypted, making the code more difficult to crack and misappropriate. Common encryption algorithms include Base64, MD5, SHA, etc. This can protect the security of the code, but it will also increase the complexity of the code and the difficulty of decryption.
4. Code obfuscation
Code obfuscation is a technique for mixing and reorganizing code. By obfuscating and reorganizing variable, function names, and other identifiers in the code, the code is made more difficult to understand and modify. This can protect the security of the code, but it will also increase the complexity of the code and the difficulty of maintenance.

lFront-end code obfuscation technique is an effective means to improve code security. However, it should be noted that excessive code obfuscation will increase the complexity of the code and the difficulty of maintenance, so a balance needs to be made between security and maintainability.
