Interresting question.

I'd say no, because cryptography is obscuring data, while steganography hides data. The difference is the medium our secret stuff is put into.
Stegos hide it somewhere, making it obviously look un-obvious, as if nothing happened. Text (for hand-written stego, and probably other electronical ones) stays human-readable, Images look (almost) the same and sound files do not have any obvious change (due to use of frequencies that cannot be heard by the human ear).
Encryption on the other hand takes something readable, and stuffs it into a format that is obviously not meant to be human-readable.

So what about multiple clear text encryption?
(like when the key is the lines and pages in a book..., the encrypted text is "hidden" in plain site)

Isnt that actually considered a stego?
Stegos arE like suCh a sentence with woRds having lEtters differently capiTalized too.

Stego is the art of hiding information and crypto is the scrambling of data to make it unreadable. Encrypted information can be hidden in Steganography using Cryptography but they are not the same thing.

cryptography is different from stego, as the others said stego is hiding data and cryptography is encrypting it. Sometimes they are used together, for example in Stego 2 there is a tiny bit of encryption in the message you find.

And in this message is some super secret stego - see if you can find it for 50 million fake hts points

I would say cryptography and stenography are pretty similar although one hides data by scrambling it, the other by hidding it within something else. The thing that will really bake your noodle is did you know can encrypt the text before you hide it in something else. I've even seen a program that hidden the text into a wave file. Unfortunatly that was years ago when I was really into it and I havent seen it since, but it just goes to show you can hide data in a lot of ways. :geek:
