What is this "alphanumeric.encode" you speak of?

I do something similar, piping to 'openssl base64', which unfortunately
produces output without a whole lot of entropy, although it usually
satisfies at least three and often all four of the standard password
character sets.

Is there something specific you use to convert to human-readable output?
