             The CRPENTPG is a 4096-byte page of storage that
             holds up to 512 8-byte CRPENTRYs.  Each CRPENTRY
             identifies an APQN to include in a pool of crypto
             resources.

     ** NOTE! Adding to the length of a CRPENTRY decreases the
     **       number of CRPENTRYs in the 4096-byte block.
     **       We document that 512 APQNs can be specified.
