Configuring password encryption

For password encryption, you must specify password encryption libraries and connection options for the simple password communication support module (CSM).

HCL Informix® provides the following shared libraries for use as CSMs. The paths and fixed file names are:

$INFORMIXDIR/lib/client/csm/libixspw.so (UNIX and Linux)
%INFORMIXDIR%\bin\libixspw.dll (Windows)

The shared libraries also have version-specific names that can be used in place of the fixed names. If you use the version-specific name, and the server is updated, you must update the concsm.cfg file.

To configure the CSM for password encryption, use the following syntax to add a line to $INFORMIXDIR/etc/concsm.cfg (UNIX and Linux) or %INFORMIXDIR%\etc\concsm.cfg (Windows).


Syntax

>>-csmname--(--“--+-client--=--clientlib--,--server--=--serverlib-+--“--,-->
                  '-csmlib----------------------------------------'         

>--""--,--“--+-------------+--“--)-----------------------------><
             '-p--=--+-0-+-'         
                     '-1-'

Option	Description
`clientlib`	The full path and name of the shared library that is the CSM on the client computer.
`csmlib`	The full path and name of the shared library that is the CSM if the CSM is shared by both the database server and the client computers.
`csmname`	The name that you assign to the CSM.
p	The password option. For CSDK version 2.3 and later, if the field is null (`""`), the default behavior is p=0. For CSDK before version 2.3, if the field is null, the default behavior is p=1. 1 The password is mandatory for authentication. 0 The password is not mandatory for authentication. If the client provides the password, it is encrypted and used for authentication.
`serverlib`	The full path and name of the shared library that is the CSM on the database server.
