Every source, and what it is used for
The record is built from the sources below. The amendment record supplies the stage, page count, edition and price. The base record and its ISO public preview supply the clause map and the requirements. The SC 27 catalogue supplies the status of the related standards.

What is not a source
Search snippets, vendor blogs, social posts and papers about the ciphers are not sources for a requirement. They can help an engineer understand a construction, but they do not become a clause on this site. Where a page says the text is not in the public preview, no secondary source has been used to fill the gap.
