want to develop encryption system as a project

[Remington]

Hey! Am new to the group and also new to JAVA programming and coding. I am doing a degree in business and IT and i am doing a final year project. My project is developing an encryption system for a shop as a measure to improve security. My desire is to come up with a way to encrypt the actual database and ensure that only the manager can hold the key to decrypt it, so it's only him who may perform editing on the data stored in it. So far I have reached the system requirement stage, what is bothering me is the coding...i need to be helped out here

What are your java coding questions?

[Remington]

I Want to create a code that performs enciphering to the plaintext(data in the database) and give a ciphertext that can only be decrypted by the key held by the manager of the shop. I was thinking of just using the caesar ciphering algorithm to do the cryptography instead of creating an encryption algorithm on my own. I can send you what i have been able to do so far so you understand better.

If you have questions about the code for your project, post them and any code that will help show the problem. Try to isolate the problem to a small program that shows the problem and does not include a lot of other code not related to the problem.
