What are the differences between obfuscation and Encryption
Below are the main differences between obfuscation and encryption,
| Feature | Obfuscation | Encryption |
|---|---|---|
| Definition | Changing the form of any data in any other form | Changing the form of information to an unreadable format by using a key |
| A key to decode | It can be decoded without any key | It is required |
| Target data format | It will be converted to a complex form | Converted into an unreadable format |
Practical Code Example
javascript
// Obfuscation vs Encryption:
// Obfuscation: Code remains valid runnable JavaScript, just hard for humans to read.
// Encryption: Transforms plaintext into unreadable ciphertext that CANNOT run without decryption key:
// const encrypted = AES.encrypt('code', 'key'); // Cannot execute directly!
