--charsN
Generate passwords with exactly N characters (do not use with options --minchars and --maxchars).
--clearfromFILE
Use password from FILE instead of generating passwords. Requires the --crypt or the --crypt-md5
options; may not be used with these options: --chars, --maxchars, --minchars, --count, --string,
--nocrypt. Trailing newlines are removed but other white space is not.
--countN
Produce a total of N passwords (the default is one).
--crypt
Produce encrypted passwords.
--crypt-md5
Produce encrypted passwords using the MD5 digest (hash) algorithm.
--cryptsaltN
Use crypt() salt N, a positive number <= 4096. If random seeds are desired, specify a zero value
(the default).
--help Ignore other operands and produce only a help display.
--maxcharsN
Generate passwords with at most N characters (default = 10).
--mincharsN
Generate passwords with at least N characters (default = 8).
--nocrypt
Do not encrypt the generated password(s) (the default).
--noverbose
Display no labels on output (the default).
--randomseedN
Use random number seed N, between 0 and 2^32 inclusive. A zero value results in a real-random
seed. This generates much less secure passwords than the default; not only does it generate
predictable passwords due to the fixed seed, but the range of available seeds is 32 bits rather
than the default of 256 bits, and cannot be changed without breaking expectations of previous
users of this option. If possible, do not use this option.
--rerandomN
Set the random seed value every N values used. Specify zero to use a single seed value (the
default). Specify one to get true-random passwords, though note that doing this too frequently
will deplete the supply of entropy available in the kernel's entropy pool.
--repeatpassN
Use each password N times (4096 maximum, --crypt must be set and --cryptsalt may not be set).
--stringSTRING
Use the characters in STRING to generate random passwords.
--verbose
Display labelling information on output.
