Random number files The random number files, /dev/random and /dev/urandom (major 4, minor 2) provide cryptographically- secure random output that was generated from the available cryptographic hardware. The foundation of this random number generation is a time-variant input with a very low probability of recycling. Requirement: In order to use these device files, Integrated Cryptographic Service Facility (ICSF) must be started and the cryptographic hardware is required, depending on the model of the server. ICSF is not required if you are using an IBM z14® server or later. For more information about the requirements, see the usage notes in Random Number Generate in z/OS Cryptographic Services ICSF Application Programmer's Guide. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
