Please note that this is a custom encryption implementation and may not be as secure as standard encryption algorithms. For real-world security, it's recommended to use well-established encryption libraries and protocols.

thank to chatGPT for the documentation

The Encrypter class provides methods to encrypt and decrKzypt messages using a custom encryption algorithm. It also offers multi-level encryption and decryption for enhanced security. The encryption process involves salting and bitwise XOR operations between the message and a derived key. Additionally, the class uses the pako library for data compression.

To use the Encrypter class, you need to import it. The class depends on the pako library for compression, so make sure you have it installed in your project.

Make a simple

npm install 

and add this line on top of your code

import Encrypter from "./path/to/Encrypter.js";

This method encrypts the provided msg using the specified encryption KEY.

• msg (string): The message to be encrypted.
• KEY (string): The encryption key.

• string: The encrypted message as a string.

This method decrypts the provided encrypted msg using the specified encryption KEY.

• msg (string): The encrypted message to be decrypted.
• KEY (string): The encryption key.

• string: The decrypted message as a string.

This method performs multi-level encryption on the provided msg using the specified KEY. The iteration parameter determines the number of encryption rounds.

• msg (string): The message to be encrypted.
• KEY (string): The encryption key.
• iteration (number): The number of encryption rounds to apply.

• string: The multi-level encrypted message as a string.

This method performs multi-level decryption on the provided encrypted msg using the specified KEY. The iteration parameter should match the number of encryption rounds used during encryption.

• msg (string): The encrypted message to be decrypted.
• KEY (string): The encryption key.
• iteration (number): The number of encryption rounds that were applied.

• string: The multi-level decrypted message as a string.

The Lib class contains utility methods used by the Encrypter class for string manipulation, binary conversions, and compression.

• static stringToBinary(string)
• static binaryToString(binaryString)
• static removeSpace(string)
• static compressString(inputString)
• static decompressString(compressedString)

Note: The Lib class is an internal implementation detail of the Encrypter class, and you should not use it directly.

Here are some examples of how to use the Encrypter class:

const KEY = "secret_key";
const message = "Hello, World!";

// Encrypt and Decrypt a message
const encryptedMessage = Encrypter.encrypt(message, KEY); // output : H4sIAAAAAAAAA03NMQ6AIAyF4StJcGUhKaORBioHgASdvP+kpdQ4fsN7fzruq51mQwg2ZfQNDGCpYsLwOkfxOg1sEvu6qGns2Vi6eu7Z4TPKXnv6//WkT+Nfep1ttff/36NzD3hn34XEAAAAc
const decryptedMessage = Encrypter.decrypt(encryptedMessage, KEY); // output : Hello, World!


// Perform multi-level encryption and decryption
const iteration = 3;
const multiEncryptedMessage = Encrypter.multiEncrypt(message, KEY, iteration); // outpupt : 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c

Some performance data

Configuration :

const KEY = "secret_key";
const message = "Hello, World!";

static multiEncrypt(msg, KEY, iteration)

• can encrypt file
• can encrypt with key's array

No idea for a encryption key ?

npm run keygen
