4 ipsec ranbits \- generate random bits in ASCII form
19 (rounded up to the nearest byte)
20 high-quality random bits from
22 and emits them on standard output as an ASCII string.
23 The default output format is
27 lowercase hexadecimal with a
29 prefix and an underscore every 32 bits.
33 option produces quick-and-dirty random bits:
34 instead of using the high-quality random bits from
36 which may take some time to supply the necessary bits if
42 which yields prompt results but lower-quality randomness.
51 but without the underscores.
57 to be interpreted as a byte count rather than a bit count.

67 There is an internal limit on
74 run time is difficult to predict.
75 A request for a large number of bits,
76 at a time when the system's entropy pool is low on randomness,
77 may take quite a while to satisfy.
