Yes and no. It has not been officialy 'beta tested' (and will probably never be), but has been used by a few people (including me) without serious problems or data loss for some time. If I called it v1.0 you probably wouldn't ask this, though the software would be the same ;).

Remembering a lot of passwords is not easy. Remebering good passwords is not easy. Remebering a lot of good passwords can be really hard. This tool helps you with exactly this problem: you enter all your passwords in the application, and it stores it on your mobile phone. Your password database is protected with a master password - the only one that you have to remember from now on. :)

The password database is encrypted with TwoFish, a strong ecryption algorithm. The encryption algorithm needs a key to encrypt and decrypt the data. This 192 bit key is generated from the master password (using PKCS#12/SHA1). If someone wants to decrypt the database, she has to have the key. The key can be generated from the password, so she has to know or guess the password. So the answer is if you choose a good password, then FreeSafe is resonabely safe.

Theoretically it should word on every j2ME/MIDP-1.0 enabled device as I use the standard MIDP API exclusively. That's the theory. In practice jFreeSafe is known to work on the following devices (as reported by some users or tried by me):

Motorola A920/A925 (with a modofied JAD file - I'll look into the problem)

Nokia 3650

Nokia 6230

Nokia 7610

Nokia 7650

Nokia 9210 Communicator

Sharp Gx10i

SonyEricsson T610

SonyEricsson P800

SonyEricsson P900

If you don't find your device here, it doesn't mean that it won't work (it really should), it just means that nobody tried it yet, or at least nobody reported it to me. If it works for you and your device is not listed (or if it doesn't work) please let me know.

Devices that don't run jFreeSafe (at the moment):

Sanyo SCP-8100 (due to some problem with some settings in the JAD/MAIFEST.MF files) but I don't have that phone, so I can't really find what the problem is. If you have such a phone and some routine with MIDlets, please try to fix it.

SGH-X100 (possibly a problem with the JAD/MANIFEST files)

Nokia 6310i (it only supports midlets up to 30k in size)

The current version does not explicitly support this. Which means that it entirely depends on your phone. As far as I know most devices do delete the data saved by an application when you upgrade it to a newer version. So if you can find the database created by the application and you can back it up and then you copy it to the appropriate place so that the new installation can access it then you'll be able to use your old data with the new version.

I know that this doesn't sound very promising but actually it's fairly easy with the so called smart phones that have a file system and a file manager application (e.g. the Nokia 9210 and 7650/3650/6600 etc.) The file you should look for is probably called 'safe'.

The next version (i.e. 0.2.7) will have explicit support for backup and thus for keeping your data when upgrading. Note that this will only work for upgrading from 0.2.7 to higher versions.
