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:
swordfish "set LineLength=75" "help user_guide"
to get a complete user guide.

Here is a sample run to show some of the features:

$ ./swordfish
>>}###@>---- format +s +x 10
password statistics are on
password expansions are on
10 passwords will be generated per template

need help. when i tried running the sworfish from the same folder that it is residing i could get the passwords working perfectly fine. However, when i tried running it from a different path by giving the absolute path i get the below mentioned warning message. i also tried running it through the shell scripts i tried a cd to the folder and then launched using the command ./swordfish.txt some times this works and some times it fails can some one help me understand why is it failing some times?

I will post a new copy of swordfish making these changes:

In the weak_start_tigershark function: the line in green is new.

function weak_start_tigershark
{
        typeset -i  i final duration
        ((final=SECONDS+2))

        while((SECONDS < final)) ; do
                i=$RANDOM
        done

        ((Carry=0))
        ((X0=$$))
        ((X1=RANDOM))
        ((X2=RANDOM))
        ((X3=RANDOM))
        ((DEBUG)) && echo weakstart X3=$X3 X2=$X2 X1=$X1 X0=$X0 Carry=$Carry
        Sum=0
        ((Stigershark=Stigershark+1))
        return 0
}


In the Main section: The lines in red go away:

if [[ $Entropy = $ZeroEntropy ]] ; then
                echo "********************************" >&2
                echo "*                              *" >&2
                echo "*  Warning:  Entropy is zero!  *" >&2
                echo "*                              *" >&2
                echo "********************************" >&2
                echo generating weak entropy... >&2
                weak_start_tigershark
                status_tigershark
                entropy_generator 1 array
                echo  Entropy = ${Entropy}

Hi,

I use your tool on Solaris 10, only i get this error.

[machine:user]$ ./swordfish
>>}###@>---- format +s +x 10
./swordfish[39]: !X0 && !X1 && !X2 && !X3 && !X4 && !Carry : bad number
password statistics are on
password expansions are on
10 passwords will be generated per template

Opps! Sorry ArcAngel, I had not noticed your report before. Better late than never I guess. There is no X4, it only goes up to X3. The fix was to remove "!X4 && " from that line. Actually, it's odd that the script ran everywhere else.

I have recently been ordered to use 12 character randomly generated passwords that meet strong complexity requirements. That is why I have dusted off this old script. I need it badly right now. Ironically, I want to to run on Solaris just like ArcAngel. I also tested it on RedHat and it broke on the latest ksh. I had to change my character slicing technique to get it work. I used to do stuff like this:

first=${x%${x#?}}

        first=$x
        while ((${#first} > 1 )) ; do
               first=${first%?}
        done

im getting sum random errors and im running ubuntu...wll screeny the errors
