Key changes:

  • Elliptic Curve Cryptography (ECC)


Targeting

  • .NET 6 is no longer supported (Microsoft end of support November 12, 2024). Use .NET 8 instead.

Component Improvements

OPC UA Client

  • OPC UA security policies with Elliptic Curve Cryptography (ECC) can now be used for communication. Supported new security policies are ECC_nistP256, ECC_nistP384, ECC_brainpoolP256r1 and ECC_brainpoolP384r1.

OPC UA Server

User Interface

  • When the component asks the user for acceptance of a peer OPC UA certificate (on Console, or on Windows desktop), it now includes a type of the public key of the certificate, indicating either RSA and the size of the key in bits, or ECDSA and the name of the elliptic curve used.
