| Compress into one line | Remove line breaks from code. |
| Identifier obfuscation mode | Set the confusion mode of variable name and function name. dictionary Use from Identifier dictionary Name in hexadecimal Randomly generated using hexadecimal mode (for example: 0xabc123 ) mangled Use a short name (for example: a , b , c , etc...) |
| Identifier dictionary | Set the name dictionary of identifier confusion. |
| Identifier prefix | Set the confused identifier to use a specific prefix Configure this option when multiple files loaded on the same page are confused. Using a different prefix for each file helps avoid conflicts between the global identifiers of these files. |
| Confusing global variables | Enabling this option may affect the operation of other codes. Please use it with caution! When enabled, global variables and global function names will be confused. |
| Self protection | When enabled, the encrypted code cannot be formatted. If someone tries to format the encrypted code, the code will not work properly. When this option is enabled, the code will be forced to be compressed into one line. |
| Control flow flattening | This option affects performance very much. Please turn it on as required! Flatten the code control flow. Control flow flattening is a source code structure transformation that hinders program understanding. visit JavaScript's obfuscator GH page Page to understand its principle. | Control flow flattening threshold | Adjustment range: 0~1, the higher the value, the more difficult the code reading is, but the output code running efficiency is correspondingly lower. It can be adjusted as required. |
|
| Dead code injection | Enabling this option will result in a larger amount of encrypted code. Random insertion of meaningless code into the code (which will not be run) makes code decryption more difficult. | Dead code injection threshold | Adjust the threshold of dead code injection (range: 0~1) |
Enable this option at the same time Convert string to array Function. |
| Split String | Enabling this option will result in a larger amount of encrypted code. Follow the text string Split string block length The set value is divided. | Split string block length | Use this option to specify the length of the block after the string is split. |
|
| Convert string to array | Remove the fixed string text in the code and put it in an array. for example var m = "Hello World"; The "Hello World" in will be replaced by a function call, and this value will be retrieved at runtime. An example: var m = _0xb0c3('0x1'); | Scramble string array positions | Put the string array in a random location. If you have a large amount of original source code, it is recommended to enable this option to greatly improve the difficulty of code decryption. | | Disrupt string array sorting | Randomly arranges the contents of a string array. | | Encrypted string array | When enabled, the code running efficiency will be slightly reduced. Encrypt strings using Base64 or RC4. RC4 encryption is difficult to decrypt after encryption, but the code operation efficiency after encryption is 30-35% lower than that of Base64 encryption. Please select as required. | | String to array threshold | You can use this setting to adjust the probability of inserting string text into the string array (from 0 to 1). This setting is useful in large code libraries because repeated calls to string array functions can slow down code speed. |
|
| Convert string to Unicode | Converts all strings to their Unicode form. For example, string "Hello World!" Will be converted to "'\x48\x65\x6c\x6c\x6f\x20\x57\x6f\x72\x6c\x64\x21" . This is too easy to decode. It's meaningless. It's not recommended to open it. The code size will be increased after opening. |
| Disable console output | Disabled by overriding to an empty function console.log , console.info , console.error and console.warn |
| Disable console debugging | When enabled, the browser will be frozen if the browser console is opened. This will make it unavailable to others Console Debugging tool for code debugging (supports Google Chrome and Mozilla Firefox browsers). | Commissioning protection timer | After starting, a timer will be used to block the console, so that the console cannot be debugged. |
|
| Domain name lock | The domain name is not qualified by default. If a locked domain name is added, the encrypted code can only run under the locked domain name How to add multiple whitelist domain names or subdomains: If necessary example.com All subdomains of are set as whitelist domain names, add .example.com OK. |
| reserved identifier | The identifiers in the whitelist will not be confused. Regular expressions are supported. For example, add ^someName Then all someName The starting variables, function names, and function parameters will not be confused. |
| Reserved string | ditto. |
| Source Map | Please make sure not to embed Source Map in the production environment, because the source code can be found through it, leading to the loss of meaning of encryption. Source maps can help you debug JavaScript code. If you have to debug in production, you can upload a separate Source maps file to a secret location, and then point the browser to that location. Inline Source Map Embed Source maps into the results of obfuscation code. It is useful if you need to debug locally. Separate Source Map Generate a separate file from Source maps together. This is useful for debugging code in production, because it allows you to upload Source maps to a secret location on the server, and then set the browser to point to that location. use Source Map Base URL and Source Map File Name Self definition sourceMappingURL And append to the end of the encrypted code. For example, if you set Base URL by " http://localhost:9000 " Set at the same time Source Map File Name by "example" , will eventually //# sourceMappingURL= http://localhost:9000/example.js.map Append to the end of the encrypted code. |
| Encrypt Seed | By default (when the seed is set to "0"), every time the same code is encrypted, the results are different (the order of variable names and strings will be different).
If you need to keep the encryption result of the same code consistent every time seed Set the value to a fixed integer. |
| Operating environment | Set where the encrypted code needs to run - Browser
- Browser No Eval
- Node
current browser and node Options are handled the same way. |
| default options | The tool has several preset protection options, which can be selected as required. | Basic protection | Default presets, high performance | | Low level protection | Low confusion, high performance, performance will be at a relatively normal level | | Intermediate protection | Medium confusion, best performance, performance will be slower than no confusion | | Advanced protection | High confusion, low performance, performance will be much slower than no confusion |
