We are working on a data scrumbling kind of utility for financial data , basically our aim is that this utility gets the data from the database , scrumbles/encrypts the data and converts it to unreadible form so that no one can understand it during the testing phase , suppose that if we have "RAZA" in the database than it would be replaced by "SBAB" (one character after the actual character) , one thing to take care is that the scrumbled data should have excatly the same length as actual data, I am totally novoice in data encryption and scrumbling , please suggest some suitable algorithim for it , if there are some APIs in java spefically for this purpose than please suggest , our basic aim is that scrumbled data should have same length as the actual data and should be again convertable to the actual form.

If you just want a very simple encryption like the example you gave, you should be able to find any number of ROT-13 examples on the web. If the data needs to remain truly secure, you'll want to encrypt the data with a password. You can check out the Java Cryptography Extension for details on how to do this.

Raza Developer, you still haven't fixed your name. I would suggest you do as Ben has suggested.
