Hi Daniel,
You're conflating key length with the name of the base algorithm.
There are three (totally distinct) NIST SHA algorithms:
SHA-1
SHA-2
SHA-3 (Keccak)
Note that SHA-3 is already being required in various new security standards
(international and regional ones) and IETF wants to aggressively deploy it
in new IETF protocols and architectures.
Cheers,
- Ira
