(This was passed onto me by a friend - Thanks!!!)

Here's an example of how to decrypt the hash to

username: admin  (used as example for this blog)
encrypted-password from registry: D1 C5 E0 DC E5 91 DC D1

the hex values of the username (admin) are: 61 64 6D 69 6E

Hence to decrypt the encrypted password, you would repeat the hex of the username until the length of the hash is matched, subtract that hex from the encrypted-password hash hex, and then convert the resulting hash/hex to ascii, and voila, you have your decrypted password:

    D1 C5 E0 DC E5 91 DC D1  (password hash from registry)
(-) 61  64 6D 69  6E 61 64  6D  (adminadm)
=  70  61 73 73  77  30 72  64  (result in hex)
=   p   a   s   s   w    0   r    d   (result in ascii)

Voila.. that was the password that I set!

This should hopefully help others who are trying to do an imail conversion.

Note:  This works with Imail Version 8.13, and may or may not work with other versions, but I suspect it will.

THIS SHOULD ONLY BE USED BY SYSADMINS TRYING TO USE THIS INFORMATION FOR CONVERSION PURPOSES!  DON'T ABUSE THIS INFORMATION.
