How do I get back the data after using $md5 ?

for example:
//echo -a $md5(saragani) gives:

e5b00bea2f85e66ffe246e4669d3cca3

How can I get back to saragani from e5b00bea2f85e66ffe246e4669d3cca3
?

You can only really use it to compare!

eg.
if ($md5(huh) == b71207f10d522d354a001768e21a78fe)

If you really must undo a decode, then use $encode and $decode. less secure, and others can get your password tho. They can $decode it too...

Thanks.

The broblem that I had is that I was working with database of my old forum ,and all the passwords were stored in md5 format.

I though of registering all the old users with their passwords.
But since I can't unto md5, I thought of a new idea: the database of the the new forum (old one xmb, new one invision) hs the passwords stored in md5 format too, to I just copied all the passwords from the old database to the new one.

Altough it doesn't seems to be connected to mIRC, it does!! because I needed to know how to undo a md5.

Thanks.

i use this,it might not be much help but,i use a text file to log the $md5's:

Code:
alias unmd5 {
if ($gettok($read(unmd5.txt,$1,s),1,32) != $null) {
  return $gettok($read(unmd5.txt,$1,s),1,32)
}
else {
return no matches found for $1
}
}
alias newmd5 {
  if ($read(unmd5.txt,$1,s) == $null) {
    /write unmd5.txt $1 - $md5($1)
    //echo -a new md5 added for $1
  }
  else {
    //echo -a $1 is already logged
  }
}

That's rather defeats the purpose of using $md5 if you're just going to have a .txt file listing everything. You're better off saving it in a hash table: hadd md5 blah $md5(blah) then you can use: hsave -bo md5 md5.dat which would make viewing the content a little harder for someone without the knowledge of how to use $hget or other ways of viewing .dat files.

Try this...

Code:
//hadd -sm md5 blah $md5(blah)
//hsave -bo md5 md5.dat
/run notepad.exe md5.dat


Then tell me how exactly $readini can open that without a [topic] and the fact that it's saved as a binary file.

saving the unencrypted and encrypted passwords in any way is totally ignoring the purpose of $md5 to begin with...

I agree, if you are gonna do that, why bother using md5 at all? All you are doing is making things slower.

It wasn't mine either. My point was, he is using md5 in a manner that adds NO security. Therefore all using md5 is doing is creating extra processing that is useless.
