The question is: how much needs to be kept confidential?
"Obscurity" general refers to situations where "everything" is confidential. And when everything is confidential priority one, nothing is, since people can't work like that.
Cryptography attempts to sequester the confidential data into a small number of bytes that can be protected, leaving larger body of data (say, the algorithm) non-confidential.
