Most OPC UA applications will conform to several, but not all, of the Profiles.
This third edition cancels and replaces the second edition published in 2015. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:

• HTTPS with JSON encoding;
• secure WebSockets (WSS) with binary or JSON encoding;
• reverse connectivity.

• transportSecurity – TLS 1.2 with PFS (with perfect forward secrecy);
• securityPolicy [A] – Aes128-Sha256-RsaOaep (replaces Base128Rsa15);
• securityPolicy – Aes256-Sha256-RsaPss adds perfect forward secrecy for UA TCP);
• user Token JWT (Jason Web Token).
d) deprecated Security Profiles (due to broken algorithms):
• securityPolicy – Basic128Rsa15 (broken algorithm Sha1);
• securityPolicy – Basic256 (broken algorithm Sha1);
• transportSecurity – TLS 1.0 (broken algorithm RC4);
• transportSecurity – TLS 1.1 (broken algorithm RC4).
