Password protection to Midlet in .Jad file

[leena viswan]

Can any one help me to know whether it is possible to provide password protection to MIdlet using .Jad file.

Could you closer specify your problem.

Here's one way of doing it: hash a passcode and store it as a custom attribute in the JAD file. In the MIDlet startup code, get the user to enter the passcode, hash it and compare to the JAD attribute's value. For a secure solution use MD5. And consider avoiding annoying the user by flagging a successful entry of the passcode in an RMS store (and check that flag on subsequent application starts). All of this adds a few KBs to MIDlet's JAR size.

As a suggestion, use numbers for a passcode - users understand the concept of a PIN.


Hope this helps
