I know the password, I just want to remove it. Mobidedrm couldn't do this (it can remove DRM from files that are not password-protected only though). any idea?

Sample file on DropBox

@Ramhound what kind of information should I add? –  Tuan Anh Tran Apr 8 '13 at 13:05
Are you trying to remove the DRM or just the password? AFAIK the .prc files are just .mobis with a different extension. apprenticealf.wordpress.com should be able to help if it's DRM. –  James Apr 20 '13 at 22:28
just the password only but the file is password protected and DRM-protected as well. –  Tuan Anh Tran Apr 22 '13 at 0:09
