I need a great Password Generator program. I looked at a few of them, but none of them seemed to be what I wanted. So I have decided to write my own. (That's the cool thing about being a programmer....I always get what I want in software :) )
Do you have any password generators that you... (13 Replies)

Does Solaris have a utility that will generate random numbers?
Thanks in advance.

Hi,
I need to create a table with random sentences. I need lines that are upto 1000 characters in lenght. I need a random sentence generator that will create sentences and output it to a text file. The sentences should be of lenght varying from 1 to 1000.

I've got a file (numbers.txt) filled with numbers and I want to replace each one of those numbers with a new random number between 0 and 9. This is my script so far:

Here is my new password generation script. The attachment, swordfish.txt, is in dos format. Remember that you need to use dos2unix or flip or something to get it into unix format.
The script is self documenting. It has an extensive help system built-in. And you can run:

There was an upload recently on generating a pseudo-random file when /dev/random does NOT exist.
This does not need /dev/random, /dev/urandom or $RANDOM either...
(I assume $RANDOM relies on the /dev/random device in some way.)
This code uses hexdump just because I like hexdump for ease of... (2 Replies)
Dear UNIX Friends,

Please share your ideas.

makepasswd
makepasswd(1) UNIX Reference Manual makepasswd(1)NAME
makepasswd - generate and/or encrypt passwords
SYNOPSIS
makepasswd [ --chars N ] [ --clearfrom file ] [ --count N ] [ --crypt | --nocrypt | --crypt-md5 ] [ --cryptsalt N ] [ --help ] [ --maxchars
N ] [ --minchars N ] [ --randomseed N ] [ --rerandom N ] [ --repeatpass N ] [ --string string ] [ --verbose | --noverbose ]
DESCRIPTION
makepasswd generates true random passwords using /dev/urandom, with the emphasis on security over pronounceability. It can also encrypt
plaintext passwords given on the command line.
OPTIONS --chars N
Generate passwords with exactly N characters (do not use with options --minchars and --maxchars).
--clearfrom FILE
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.
--count N
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.
--cryptsalt N
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.
--maxchars N
Generate passwords with at most N characters (default = 10).
--minchars N
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).
--randomseed N
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.
--rerandom N
Set the random seed value every N values used. Specify zero to use a single seed value (the default). Specify one to get true-ran-
dom passwords, though note that doing this too frequently will deplete the supply of entropy available in the kernel's entropy pool.
--repeatpass N
Use each password N times (4096 maximum, --crypt must be set and --cryptsalt may not be set).
--string STRING
Use the characters in STRING to generate random passwords.
--verbose
Display labelling information on output.
HISTORY
makepasswd was originally part of the mkircconf program used to centrally administer the Linux Internet Support Cooperative IRC network.
It may potentially be of use in any situation where passwords must be secure and need not be memorized by humans.
Colin Watson modified it to use OpenSSL's pseudo-random number generator.
