I use Outlook Express with several identities. I've forgotten my password to one identity which logs on to Hotmail and I know that the password is encrypted somewhere on my machine. I've found in the register all the info I need together with the HTTPMail Password2= 01, 02, 03 and so on.

I'd really appreciate some help on how to decrypt this binary or info on where to look to get this password. I'm a newbie and aplogize if I offend someones intelligence... Hope for help anyway though...

Try a tool called "CAIN 1.51".h$$p://www.confine.com/downloads.shtml
It may help you decript your password. I have not used with Outlook Express specifically, but it has done a decent job when I have had the need.

Outlook stores the CRC of the password in the .pst file. Any password with the same CRC is accepted.

What kind of encryption did you use? If it's "none" or "compressible," you can search for a signature in the file.

none: ff670300 next 4 bytes are CRC

compressible encryption replaces each byte x with firsttable[x]

unsigned char firsttable[256]=

};

so you would need to look for firsttable[ff 67 03 00] = [3d 53 62 41] and
the next 4 bytes are the encrypted CRC. Invert the table above to
figure out the actual bytes

CRC is linear and invertable, so you shouldn't have much trouble in finding
a password that's all printable characters. Write me if you need help.

If you used "best" encryption, there's no signature to search for. Download one of the shareware programs that does outlook password recovery and hack it or pay for it.
