Which would be the best way of encryption for following scenario?

Question

I want to know which would be the best java encryption type I can use to secure my application authentication details. In my application I have to use credentials for database and one application. I am putting it in one properties file.

db_username = abc
db_password = password 

If I dont want my password to be visible in properties file. But I cant hardcode it in my application. Its a command prompt application and run using script which runs it automatically. What are the available encryption methods I can use?

Thanks..

Answer 1

You could take the username and password as arguments to your program, which you would call like this for example:

java -jar yourProgram -user john -pass 1234

You then move the security issue to the OS (make sure your batch is only accessible by authorised users).

Alternatively you can pass a properties file, which you place is a secure location.
