I have a number of nodes that I need to update the EnablePassword stored in the NCM Nodes table in NCM 7.3. As these values are stored in an encrypted format, I'm wondering how I can update them via the SDK?
The verb Cirrus.Settings.EncryptData takes a arbitrary string (in your case, the new password in plaintext) and returns that string encrypted by NCM's method and base64-encoded. You can then use a regular SWIS Update operation to store this encrypted password in NCM.Nodes.EnablePassword.
