When you start ICSF, you use the ICSF panels to run the pass phrase initialization utility. When you access the ICSF panels, the primary menu panel appears. Note that the ICSF FMID appears in the upper left hand corner (it will toggle to the panel identification ID).
Select option 6, PPINIT, and press ENTER to begin the pass phrase initialization utility. The pass phrase panel appropriate for your hardware configuration will appear.
This utility uses the pass phrase, a series of constants, and the MD5 and SHA-256 hash functions to calculate the value of the master keys. For details on how the values of master keys are calculated, see Pass Phrase Initialization master key calculations.
