Message Encryption

Secure user communication by implementing end-to-end encryption for messages. Encrypting messages ensures that only intended recipients can decipher the content. Below is a high-level overview, and the actual implementation may depend on your chosen encryption library or framework:

Key Exchange: Establish a secure key exchange mechanism between users involved in the conversation. Implement a secure way to exchange encryption keys, such as utilizing public-private key pairs.

Message Encryption: Encrypt messages using the exchanged keys. Choose a strong encryption algorithm (e.g., AES) to secure the content.

Decryption: Ensure that only the intended recipient possesses the necessary key to decrypt the message. Implement secure decryption mechanisms on the recipient's side.

Example usage (conceptual):

function generateEncryptionKeys() {
  // Implementation details to generate encryption keys
}
 
// Function to encrypt a message
function encryptMessage(message, encryptionKey) {
  // Implementation details to encrypt the message
}
 
// Function to decrypt a message
function decryptMessage(encryptedMessage, decryptionKey) {
  // Implementation details to decrypt the message
}
 
// Example usage
const user1EncryptionKeys = generateEncryptionKeys();
const user2EncryptionKeys = generateEncryptionKeys();
 
const originalMessage = 'Sensitive information';
const encryptedMessage = encryptMessage(originalMessage, user1EncryptionKeys.publicKey);
 
console.log(`Encrypted Message: ${encryptedMessage}`);
 
const decryptedMessage = decryptMessage(encryptedMessage, user2EncryptionKeys.privateKey);
console.log(`Decrypted Message: ${decryptedMessage}`);

This is a simplified example, and in a real-world scenario, you would need to handle key management securely, use reputable encryption libraries, and ensure proper implementation of encryption and decryption functions.
