Merge branch 'bc/sha-256'
Add sha-256 hash and plug it through the code to allow building Git with the "NewHash". * bc/sha-256: hash: add an SHA-256 implementation using OpenSSL sha256: add an SHA-256 implementation using libgcrypt Add a base implementation of SHA-256 support commit-graph: convert to using the_hash_algo t/helper: add a test helper to compute hash speed sha1-file: add a constant for hash block size t: make the sha1 test-tool helper generic t: add basic tests for our SHA-1 implementation cache: make hashcmp and hasheq work with larger hashes hex: introduce functions to print arbitrary hashes sha1-file: provide functions to look up hash algorithms sha1-file: rename algorithm to "sha1"
