block88 🔐

block88 is a lightweight, layered string encoding/decoding tool that combines multiple techniques such as key-based shifting, Base64 encoding, ROT13 cipher, and run-length compression. It’s useful for obfuscation, simple data manipulation, and encoding non-sensitive information in a reversible manner.

⚠️ Disclaimer: block88 is not a cryptographic tool and should not be used for securing sensitive data. It is designed for simple obfuscation purposes.

✨ Features

• Key-based ASCII shifting: Shifts characters by the ASCII value of the key.
• Base64 encoding: Converts the string into Base64 format.
• ROT13 cipher: Applies the ROT13 transformation to the string.
• Run-length compression: Compresses the string by reducing consecutive repeating characters.
• Symmetrical decoding: Decoding a string returns the original input when using the same key.

📦 Installation

You can install block88 via npm:

npm install block88

or via Yarn:

yarn add block88

🔧 Usage

Here’s an example of how to use block88 for encoding and decoding strings:

const { encode, decode } = require('block88'); // Adjust path if using locally
const key = "key";  // The encryption key
const string = "Hello World!";  // The string to encode

// Encoding the string
const encrypted = encode(string, key);
console.log("Encrypted:", encrypted);

// Decoding the string back to the original
const decrypted = decode(encrypted, key);
console.log("Decrypted:", decrypted);  // Output: "Hello World!"

🧪 API

encode(text: string, key: string): string

Encodes a string using a combination of:

• Key-based ASCII shifting
• Base64 encoding
• ROT13 ciphering
• Run-length compression

decode(encoded: string, key: string): string

Decodes an encoded string back to its original form by reversing the encoding steps.

⚠️ Disclaimer

block88 is not a secure encryption tool. It should only be used for obfuscation or light encoding purposes. Do not use it to secure sensitive data, as it is not cryptographically safe.

⚠️ Warning

block88 do not use version 1.0.0 its broken.
