The GetAgentPasswordHashKey Web service is used as part of the optional client-side encryption feature. It returns a temporary hash key used by the client to encrypt a password for a single authentication call. The client encodes the password with this hash key. The server then stores the hash key in the current session so you do not have to return it to the LoginAgentUser service.

For more information, see the GetAgentPasswordHashKey section of the Commerce Service Center Installation and Programming Guide.

Note: See the Personalization Programming Guide for more information about using client-side password encryption.
