Each security mechanism provides a set of security services that establish a secure connection between a client and a server. Each security service addresses a particular security concern. Security services can be divided into two broad categories:
Authentication services
Per-packet security services
See the Open Client Client-Library/C Reference Manual for a complete discussion of security services.
Client-Library applications set connection properties to request a mechanism’s services. Open Server applications read the properties of a client thread to determine which services are being performed.
