Strip (Secure Tool for Recalling Important Passwords) is a password and account manager for the Palm(tm) organizers. It allows you to use your handheld to keep a complete inventory of accounts without worrying about your data falling into the wrong hands. Strip uses strong 128 bit encryption. Unlike other account management software, everything is encrypted, even your systems/categories. Strip also has the capability of generating random passwords and pin numbers.
