The incoming call is authenticated by security-auth(2). After successful authorisation, the client can request that a digest and/or encryption algorithm be applied to protect the data exchanged with the server. Each alg names a digest or encryption algorithm that the server will allow the client to use, in any form accepted by ssl(3); the special name none means that ssl need not be used.

The implementation of dbsrv relies on a program external to Inferno, infdb, which translates between the db(7) internal format for requests, and data base access calls on the host. Dbsrv invokes infdb using the cmd(3) device. Currently infdb is implemented only under Windows/NT, giving access via ODBC to a Microsoft Access data base.
