Recommended Algorithms for Mainframe Environment
 
 The crypto hardware devices available on zSeries machines implement 
certain algorithms. Although SSH Tectia Server (M) includes all the algorithms 
available in SSH Tectia Client and Server 5.0 products on other 
platforms, using hardware acceleration is recommended because it will 
reduce the CPU usage. To take advantage of hardware acceleration, use 
the following algorithms:
 
-  Cipher: Triple DES with CBC (
3des-cbc)
 -  MAC: SHA-1 (
hmac-sha1)
 
 These are the defaults in the configuration files that the setup script installs.
