I decided to write for yourself a password vault(just out of interest). With the development of such applications never the case had therefore got up the next question.

How to organize the storage of encrypted data? Desirable random access to the data.

XML or sqlite. Simple text-based format, presented above, will limit you to a single-line description, or the need to come up with their own escape sequences. And when you solve this problem, you will get another pre-XML (which is not needed).

How long ago was using tools KeePass — all records were stored in one file *.key. It was very easy to carry it with you everywhere.

Can come up with some kind of a format: CATEGORY | DESCRIPTION | LOGIN | PASSWORD. Store all in a file and encrypt it with AES/Blowfish etc. This is the easiest way.

You can consider the option database. But as you write for yourself and just out of interest, I think it's redundant.

I once wrote for myself, a program for storing passwords.
MD5, and everything else not used. Decided to encrypt according to Vigenère Cipher.
Need only the key and the table to create. Well, then no problem.
Good luck in writing the program!
