When the KMF Profile Selection field is not set to "Disabled", this field for the current Data Profile can only select keys from the Secure Hardware Encryption Key References List of this selected Secure KMF Profile.

DotRed.png Be aware that the CPS is actually pointing to the Keys of the Encryption Key List for this selection; individual Keys from the Secure Hardware Encryption Key References List reference the Encryption Key List's Keys from the Hardware Key Reference field. WFPrior.png Therefore any key selected when ASTRO OTAR is enabled, must first be defined in the Secure Hardware Encryption Key References List.

 

When the KMF Profile Selection field is set to "Disabled", this value for the current Data Profile is directly chosen from the Secure Wide Window's Encryption Key List.
