Get existing password of Internet User

Hi all,

I have a requirement in which i need to transfer the Internet User ID and Password from CRM to another cleint system.

my question is: can we access the current password of an internet user???? (SU01)

if yes, how???

as per my understanding, the password is stored after using a hash key algorithm which encrypts the password.

So can we decrypt that password???

please advice???

Thanks and Regards
