Secure Node Communication (TLS)
Configure Erlang nodes to communicate securely using TLS/SSL, encrypting data in transit across the network.
Why Secure Erlang Nodes?
When Erlang nodes communicate, especially across a network or in a production environment, their interactions need to be secure. This prevents eavesdropping, tampering, and unauthorized access.
By default, Erlang's distribution protocol doesn't encrypt communication. This lesson will show you how to add a layer of security using TLS/SSL.
TLS: The Security Handshake
TLS (Transport Layer Security) and its predecessor SSL (Secure Sockets Layer) are cryptographic protocols designed to provide communication security over a computer network.
They achieve this by:
- Encryption: Scrambling data so only the intended recipient can read it.
- Authentication: Verifying the identity of the communicating parties.
- Data Integrity: Ensuring data hasn't been altered in transit.
