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 (
- MAC: SHA-1 (
These are the defaults in the configuration files that the setup script installs.
