Protocol

SSL/TLC:
Transport Layer Security (TLS) – and its predecessor, Secure Sockets Layer (SSL), which is now deprecated by the Internet Engineering Task Force^[1] (IETF)

TLS and SSL do not fit neatly into any single layer of the OSI model or the TCP/IP model.^[8][9] TLS runs “on top of some reliable transport protocol (e.g., TCP),”which would imply that it is above the transport layer. It serves encryption to higher layers, which is normally the function of the presentation layer. However, applications generally use TLS as if it were a transport layer,^[8][9] even though applications using TLS must actively control initiating TLS handshakes and handling of exchanged authentication certificates.

Protocol	Published
SSL 1.0	Unpublished
SSL 2.0	1995
SSL 3.0	1996
TLS 1.0	1999
TLS 1.1	2006
TLS 1.2	2008
TLS 1.3	2018

TLS typically relies on a set of trusted third-party certificate authorities to establish the authenticity of certificates. Trust is usually anchored in a list of certificates distributed with user agent software,^[35] and can be modified by the relying party.

 

encryption algorithm

RSA
RSA (Rivest–Shamir–Adleman) is one of the first public-key cryptosystems and is widely used for secure data transmission. In such a cryptosystem, the encryption key is public and it is different from the decryption key which is kept secret (private).
DHE–RSA (forward secrecy)
PSK–RSA
PSK
To build a key from shared secret, the key derivation function is typically used. Such systems almost always use symmetric key cryptographic algorithms. The term PSK is used in Wi-Fi encryption such as Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), where the method is called WPA-PSK or WPA2-PSK, and also in the Extensible Authentication Protocol (EAP), where it is known as EAP-PSK. In all these cases, both the wireless access points (AP) and all clients share the same key.

 

cipher

AES GCM, AES CCM, AES CBC, ChaCha20–Poly1305,

AES128 is a symmetric block cipher. SHA256 is a hash which is used as part of a message authentication code (HMAC). ECDHE is a key-exchange protocol, which is used as the handshake to establish the ephemeral keys used with the cipher.

 

HTTPS

In HTTPS, the communication protocol is encrypted using Transport Layer Security (TLS), or formerly, its predecessor, Secure Sockets Layer (SSL). The protocol is therefore also often referred to as HTTP over TLS,^[3] or HTTP over SSL.
