TLS = Protocol

DHE = Diffie-Hellman ephemeral (provides Perfect Forward Secrecy)

    Perfect Forward Secrecy = session keys won’t be compromised, even if server private keys are

Past messages and data cannot be retrieved or decrypted (https://en.wikipedia.org/wiki/Forward_secrecy)

 

RSA = Digital Signature (authentication)

    There are only 2 (RSA, or ECDSA)

 

AES_256_GCM - HMAC (hashed message authentication code)
