wikipedia:Transport Layer Security cryptographic protocol successor to SSL (deprecated since 2011).

Once the client and server have agreed to use TLS, they negotiate a stateful connection by using a handshaking procedure. The protocols use a handshake with an asymmetric cipher to establish not only cipher settings but also a session-specific shared key with which further communication is encrypted using a symmetric cipher.




macOS 10.15 (June 2019) and IOS 13 requirements (https://support.apple.com/en-us/HT210176)

  • TLS server certificates and issuing CAs using RSA keys must use key sizes greater than or equal to 2048 bits
  • SHA-2
