You can configure CICS Transaction Gateway to use the SSL
cryptographic protocol for security and data integrity of communications
over a TCP/IP connection.
Configuring server authentication with iKeyman
You configure server authentication by creating a client
keyring, importing the server's signer certificate, creating
a server keyring and certificate, and exporting the server's
signer certificate.
SSL key ring configuration
To use SSL for connections between Java client applications
and the Gateway daemon, or to use SSL for IPIC connections to CICS,
you must configure the SSL key ring in the configuration file, ctg.ini.
