How do I securely transfer sensitive data over the internet?

1. Use an encrypted connection such as SSL/TLS to ensure your data is safe while in transit.
2. Authenticate each user prior to data transfer. Use strong authentication methods like two-factor authentication.
3. Never transfer passwords in plain text. Instead, use an approved hashing algorithm.
4. Use digital signature validation to verify the identity of the sender with the help of digital certificates.
5. Ensure that data is stored using encryption methods such as AES, Blowfish, etc.
