record layer
The part of TLS that chops your data into chunks and encrypts each one for sending.
Underneath a secure connection, the TLS record layer is the plumbing that takes application data, splits it into records, and encrypts and authenticates each before it goes on the wire. It sits below the handshake and carries every byte the two sides exchange once the connection is secured. Getting its framing and encryption exactly right is essential to security.
