What is JPasswords?

JPasswords is a password management program with encrypted databases. It allows you to store passwords or passphrases, together with related management data like username, entry title, dates and notes, on encrypted disk files. Access to such a file is protected by a single secret key that you can define and change at any time. The currently used database format is deemed by experts as one of the most secure you can find anywhere. JPasswords allows you to set different security levels to hamper password guessing attacks by time delay.

Password entries may be ordered within groups (which can be nested) and displayed in tree or in table view. Upon retrieval of a password, the program assists you with a "copy to clipboard" function to make password or username quickly available for other applications. Several useful service functions, like file copy, automatic backup and restore, but also secure file erase, elaborate undo/redo and a versatile portable modus make this program a pleasure to use and a singular event in the market.

Format and encryption method for the database files are compatible with "Password Safe" V3 files as created by CounterPane's (Bruce Schneier) program of the same name.
