This option is meant to be used when reading additional randomness from a file or device. ++ +The _number_ argument may be followed by the multiplicative suffixes KiB=1024, MiB=1024*1024, and so on for GiB, TiB, PiB, EiB, ZiB and YiB (the "iB" is optional, e.g., "K" has the same meaning as "KiB") or the suffixes KB=1000, MB=1000*1000, and so on for GB, TB, PB, EB, ZB and YB. + +*-v*, *--verbose*:: +Inform where randomness originated, with amount of entropy read from each source. + +include::man-common/help-version.adoc[] + +== FILES + +_/dev/urandom_ + +_/dev/random_ + +== BUGS + +It is assumed that none of the randomness sources will block. + +== SEE ALSO + +*md5sum*(1), +*X*(7), +*xauth*(1), +*rand*(3) + +include::man-common/bugreports.adoc[] + +include::man-common/footer.adoc[] + +ifdef::translation[] +include::man-common/translation.adoc[] +endif::[] -- cgit v1.2.3
