What do you think? Is it a good tag? I can create tags, but wanted to get the thoughts of the community first.
We already have cryptography ... is there a difference?
Maybe there's a need to retag some questions, and I can see a need to make encryption a synonym to cryptography.
It was pointed out that we already have a cryptography tag, but encryption is just a subset of crytography; along with hashing. SO has a tag for it as well. I'm of the opinion that more specific tags lead to better categorization. One may want to follow questions about encryption, but not hashing and vice versa.
Quote from a relevant discussion on Meta SE:
The difference between cryptography and encryption on the other hand is entirely practical. Most questions that have to do only with encryption are correctly tagged with encryption and most questions that have to do with anything else are tagged cryptography. That's useful to me and both have enough followers to merit a split.
