Subject: RE: passwords with fixed position characters and numbers
Thanx Solar!
And thanks for the explanation of me-sort-of-trying-to-write-a-valid-code.
I knew it wasn't ok, but after all, I learned al lot of it because of your
explanations.
Here are some results after messing with some options in John and Sippcrack
together.
(Let's say historical puposes)
$Benchmarks:
Because I have a 1.8Ghz Dualcore AMD with 3 gig of memory (work is fun
sometimes)
and Solar tried it on a P3 1 gig...and generated +-1.000.000 passwords, that
was the number to achieve at the least minimum.
External ouput on screen....I knew that would be slow.... 3.000
/s //or so..gave up immediately :-)
External ouput (--stdout) on Guest Virtual Machine (Backtrack2): +-30.000...
/s //hmm...we're getting somewhere
External Output (--stdout) on Win Vista (Hate it)
+-30.000.... /s // hm...something is not right
External output on Livecd Backtrack2...
+-30.000...../s // Gotta read all the options again...
With option --stdout=8 > filename
+-3.235.000...../s ///Yeay!!! Really gotta donate this guy something
About the script and to see I can follow what it does:
To get an output of 0000aaaa (reversed output) I have to reverse a part of
code into:
.............
/* This defines the character sets for different character positions for
reversed output of original script */
pos = 0;
while (pos < 4) {
ofs = pos++ << 8;
i = 0;
c = '0';
while (c <= '9')
charset[ofs + i++] = c++;
charset[ofs + i] = 0;
}
while (pos < length) {
ofs = pos++ << 8;
i = 0;
c = 'a';
while (c <= 'z')
charset[ofs + i++] = c++;
c = 'A';
while (c <= 'Z')
charset[ofs + i++] = c++;
charset[ofs + i] = 0;
}
~....................................~
I will try, I gotta have some sleep now, a miracle (a baby) is coming in
within a few weeks..or days..who knows...
