I want the passphrase to be kept secret, not available in the source code.

Only way around this is to put the passphrase in a seperate file which you read out of each time your program runs. The file should be only be readable by the username your software runs under. You can run the passphrase through SHA1 first and set that value as the passphrase, so at least the passphrase wouldn't be in plaintext.

I know, this isn't the best solution. It's mearly the only solution. In a perfect world, a human would manually enter the passphrase every time. This doesn't sound like an option for you, so I present this flawed but useable solution instead.

I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident.
