- TLS Version(s):
- TLS1.2, TLS1.3
- Protocol:
- Transport Layer Security (TLS)
- Key Exchange:
- Pre-Shared Key (PSK)
- Authentication:
- Pre-Shared Key (PSK)
- Encryption:
- AEAD ChaCha stream cipher and Poly1305 authenticator (CHACHA20 POLY1305)

Non-ephemeral Key Exchange:
This key exchange algorithm does not support Perfect Forward Secrecy (PFS) which is recommended, so attackers cannot decrypt the complete communication stream.
