LemmEncode - Let Me Encode!

LemmEncode is a simple encoding library that uses a combination of a secret key and a random salt to encode and decode strings. The encoded output is in Base64 format, ensuring that it can be easily stored and transmitted. The use of a random salt ensures that the encoded outputs are always different, making dictionary and brute force attacks more difficult.

Installation

You can install the package using npm:

npm install lemmencode

Usage

Importing the Library

First, import the necessary functions from the library:

import { encodeString, decodeString } from "lemmencode";

Encoding a String

To encode a string, use the encodeString function. You need to provide the data you want to encode and a secret key.

const data = "Hello, World!";
const key = "mySecretKey";
const encodedData = encodeString(data, key);

console.log("Encoded Data:", encodedData);
// Example output: "ZDgxYTc4ZGY2M2M3MzJiMTYwN2YyNGM0Oj09QUFBQXhBeUFBQUFBQUFBSWFBQUFBQUFBRjdtZ2R3PT0="

Decoding a String

To decode a string, use the decodeString function. You need to provide the encoded data and the same secret key used for encoding.

const decodedData = decodeString(encodedData, key);

console.log("Decoded Data:", decodedData);
// Output: "Hello, World!"

Functions

encodeString(data: string, key: string): string

Encodes the given data using the provided key.

• data: The string you want to encode.
• key: The secret key used for encoding.

Returns: A Base64 encoded string that includes a random salt.

decodeString(encodedData: string, key: string): string

Decodes the given encoded data using the provided key.

• encodedData: The Base64 encoded string that you want to decode.
• key: The secret key used for decoding.

Returns: The original string data.

Example

import { encodeString, decodeString } from "lemmencode";

const key = "mySecretKey";
const data = "Sensitive Information";

// Encoding the data
const encodedData = encodeString(data, key);
console.log("Encoded Data:", encodedData);
// Example output: "ZDgxYTc4ZGY2M2M3MzJiMTYwN2YyNGM0Oj09QUFBQXhBeUFBQUFBQUFBSWFBQUFBQUFBRjdtZ2R3PT0="

// Decoding the data
const decodedData = decodeString(encodedData, key);
console.log("Decoded Data:", decodedData);
// Output: "Sensitive Information"

Security Note

While LemmEncode provides a basic level of security through obfuscation, it is not a substitute for robust cryptographic algorithms for securing highly sensitive data. For more secure applications, consider using established cryptographic libraries and practices.
