Transaction Layer Security
Use this information to know about the transaction layer security.
Transport Layer Security (TLS) is a protocol that ensures privacy and data integrity in communications between the client and server.
TLS is composed of two layers:
- The TLS Record Protocol
- Provides connection security with data encryption methods such as the Data Encryption Standard (DES) or RC4 without encryption. The keys for this symmetric encryption are generated uniquely for each connection and are based on a secret that is negotiated by the TLS Handshake Protocol. The Record Protocol can also be used without encryption.
- The TLS Handshake Protocol
- Enables the server and client to authenticate each other and to negotiate an encryption algorithm and cryptographic keys before data is exchanged.
Note: TLS and SSL are not interoperable. Providing a
start TLS request (the -Y option) over an SSL port
causes an operations error.
