+# Signing Key pair generation using Node.js
+
+This Node.js script generates key pairs for signing and encryption using the `tweetnacl` and `crypto` library.
+
+## Prerequisites
+
+Make sure you have Node.js installed on your system. If not, you can download it from [Node.js website](https://nodejs.org/).
+
+## Installation
+
+```bash
+npm i
+```
+
+## Usage
+
+- Clone the repository or copy the script into your project.
+- Run the script using the following command:
+
+```bash
+node index.js
+```
+
+## Output
+
+The script will output key pairs in base64-encoded format for signing and encryption.
+
+```bash
+{
+    "Signing_private_key": "BASE64_ENCODED_PRIVATE_KEY",
+    "Signing_public_key": "BASE64_ENCODED_PUBLIC_KEY",
+    "Encryption_Privatekey": "BASE64_ENCODED_PRIVATE_KEY",
+    "Encryption_Publickey": "BASE64_ENCODED_PUBLIC_KEY"
+}
+
+```
+
+## Example
+
+```javascript
+const keyPairs = generateKeyPairs();
+console.log(keyPairs);
+```
+
+Feel free to integrate this script into your project or use it as a reference for key pair generation in Node.js.
+
+```vbnet
+Copy and paste this markdown content into a `readme.md` file in your project repository. Modify it as needed based on your project structure and additional information you want to provide.
