# encryptData Function Documentation

The `encryptData` function takes two parameters: `data` (string) and `receiverPublicKeyHex` (string). It encrypts the given data using AES encryption algorithm with a shared key derived from the sender's private key and receiver's public key. The function returns an object with two properties: `secret` (the encrypted data) and `senderPublicKeyString` (the sender's public key string).

## Parameters
- **data** (String): The data to be encrypted.
- **receiverPublicKeyHex** (String): The hexadecimal representation of the receiver's public key.

## Return Value
An object containing the following properties:
- **secret** (String): The encrypted data.
- **senderPublicKeyString** (String): The sender's public key string.

## Example Usage
```javascript
const data = "Hello, World!";
const receiverPublicKeyHex = "receiver_public_key_hex_here";

const encryptedData = floCrypto.encryptData(data, receiverPublicKeyHex);
console.log("Encrypted Data:", encryptedData.secret);
console.log("Sender's Public Key:", encryptedData.senderPublicKeyString);
