  • None: No encryption type.
  • Basic256Sha256: 256-Bit encryption. It supports Sha256 or stronger hash algorithms for certificates.
  • Basic256: 256-Bit encryption. It supports the Sha1 and Sha256 hash algorithms for certificates.
  • Basic128Rsa15: 128-Bit encryption that uses RSA15 as a Key-Wrap. It supports Sha1 or stronger hash algorithms for certificates.
  • Aes256_Sha256_RsaPss: 256-bit Advanced Encryption Standard (AES) using the RSA Probabilistic Signature Scheme.
  • Aes128_Sha256_RsaOaep: 128-bit Advanced Encryption Standard (AES) using the RSA with Optimal Asymmetric Encryption Padding.

Restart OPC UA Server

After enabling or disabling a policy, you must restart the OPC UA Server. See Manage the OPC UA Server to learn more.
