developing a password vault
I wish to develop a password vault in java. hopefully everyone knows what it is. and for those who dono let me explain.
1. this tool is used in software companies providing services
2. when the client s in one place and the service engineer is in some remote place then client can explain his problem thru remote desktop sharing i.e engineer can view client's system thru some software. but it requires a password from the client so that engineer can enter it and get authenticated.
3. in some cases client s not willing to say the password fearing it may be shared to someone else.
4. here comes the "password vault". this tool gets the password from client and generates a serial no for it. it locks the serial no with this client so that this no will not be provided for some other clients until the client's problem s cleared and the lock is released.
5. now i wish to know how to generate serial no randomly and also how to make this lock-release mechanism i.e,not providing the serial no to some other client whwn its in use.
have a look at the illustration picture
