• File mkpw.c — part of check-in [6b3b3fa87f] at 2019-07-19 11:47:45 on branch trunk — switch from syscall to getrandom (user: lexi, size: 6059) [annotate] [blame] [check-ins using]

    11     11    *  → mkpw is unlikely to be portable to non-POSIX
    12     12    *    systems, but should run fine on Linux as well
    13     13    *    as BSDs with getrandom() support.
