Test vectors for SHA-1, SHA-2 and SHA-3

This page summarises useful test vectors for the secure hash algorithms SHA-1, SHA-2 and the more recent SHA-3 (approved as a FIPS standard in August 2015 [6]).

The examples for "abc" and the like for SHA-1 and SHA-2 used to be in the appendix of FIPS-180, but then got moved off to a separate document on the NIST Example Algorithms page.
