Issue/Introduction

How do we configure XCOM for AS/400 to use TLS 1.2 for secured transfers?

Environment

Release : 11.0

Component : XCOM Data Transport for iSeries(AS/400)

Resolution

The value of the SSL_METHOD section in the configssl.cnf file need to change to the following:

[SSL_METHOD]
INITIATE_SIDE = ALL
RECEIVE_SIDE  = ALL

or 

[SSL_METHOD]
INITIATE_SIDE = TLSv1.2
RECEIVE_SIDE  = TLSv1.2

When the value of "ALL" is specified then XCOM will support all of the SSL protocols, such as v3, TLS 1.0, TLS 1.1, and TLS 1.2. If the value is specific to the support protocol such as "TLSv1.2" then the secured transfers will use TLS 1.2 only.
