Create new users in Report server, password encryption

[alxalx]

Hello Everyone,

 

I am migrating a list of users from another system(not Jasper) into Report Server. For each user I receive it's login name and Password. My attempt was to insert in Jiuser table and related tables the new users.

My problem is that in Postgre Jiuser table the password is encrypted. How can I generate the encrypted string from my text file containing passwords, so that Jasper can decrypt and use this password after the insert in Postgre tables

Thanks in advance
