Securing data
Network data encryptionUse network encryption to encrypt data transmitted between server and client, and between server and other server.
Communication support modules for data transmission encryptionYou can use the communication support modules (CSMs) to encrypt data transmissions, including distributed queries, over the network.
Network data encryption syntaxYou must specify network encryption libraries and options in the concsm.cfg file.
Invoking an encryption parameters file in concsm.cfgYou can configure encryption options by setting encryption parameters in a file and then invoking it in the concsm.cfg file.
Example of encryption parameter fileThe encryption parameter file specifies values for encryption parameters.

Example of encryption parameter file

The encryption parameter file specifies values for encryption parameters.

The following example shows an encryption parameter file:

ENCCSM_CIPHERS         all
ENCCSM_SWITCH          120,60
ENCCSM_MAC             medium
ENCCSM_MACFILES 			 /usr/informix/etc/MacKey.dat

The following example illustrates a line in the concsm.cfg file to specify encryption with a parameter file named encrypt.txt:

ENCCSM("usr/informix/lib/cms/iencs11a.so",
"config=/usr/lib/encrypt.txt")
