The standard commercial message is an XML document transferred over the global TCP/IP network. The encription level is usually triple- DES, often poorly implemented. With my specialized hardware (a souped-up version of the NSA's own equipment) I can decript these kind of messages in real time.

Military operations and big corporations like Wayne Enterprises and LexCorp routinely use more advanced algorithms. It takes me three or four hours to break into their communication channels, less if I link with Bruce's mainframes at the Cave.

Impossible-to-break semisentient codes from advanced civilizations are much tougher, of course. You need Kryptonian self-adaptive processors and Apokoliptian signal processing algorithms to read those. Sometimes a week or two goes by before I can adquire and configure the necessary resources.

*This*... this is a piece of common white paper with four words written on it. A piece of paper I found on your jeans an hour ago, when I wanted to surprise you by washing them. The words are written in Helena's handwriting, Dick.

"Last night was great".

I can read them well enough. But I don't understand.
