Change this program example to suit your needs for setting the min and max values for master key shares in your Cryptographic Coprocessor.
D************************************************************* D* SETMOFN D* D* Set the M-of-N values in the Cryptographic Coprocessor. These values D* are used in cloning of the master key. The master key is D* cryptographically split into N number of parts and M number of D* parts are needed to recover it.
