hsm stc cipher disable

Disable the use of a symmetric encryption cipher algorithm for data encryption on the secure trusted channel (STC) admin channel.The STC admin channel is local to the appliance, and is used to transmit data between the local services and applications running on the appliance (such as LunaSH, NTLS, and the STC service) and the HSM SO partition.

NOTE   The STC admin channel is configurable using Luna Network HSM appliance software and Luna HSM firmware 7.4.x and earlier. This feature is not available in Luna Network HSM 7.7 and newer.

All data transmitted over the STC link will be encrypted using the cipher that is both enabled and that offers the highest level of security. For example, if AES 192 and AES 256 are enabled, and AES 128 is disabled, AES 256 will be used. You can use the command hsm stc cipher show to show which ciphers are currently enabled/disabled.

NOTE   Performance is reduced for larger ciphers.
