rgw_cksum: add trival test vectors for sha-format digests
Computed digests match those produced by sha1sum, sha256sum,
and sha512sum utilities.
rgw_cksum: add test vectors for blake3
Tests the same input strings with digests validated by
b3sum (https://crates.io/crates/b3sum).
rgw_ckum: switch to accel crc32c
The internal Ceph convention appears to be to omit a final
xor where ceph_crc32c is used, but it's required for compatibility
with AWS implementations.
rgw_cksum: add XXH3 digest
rgw_cksum: write class encoder for rgw::digest::Cksum
rgw_cksum: also reverse crc32c (REBASEME)
Mark noticed that the crc32c output was being tested against a
byteswapped value (crc32c also needs byteswap on LE).
rgw_cksum: add digest::Cksum serde tests
rgw_cksum: fix main(...) linkage
(so we run our main unit and not the one in gmock
rgw_cksum: convenience extensions for integration with RGW/S3
introduce rgw_cksum unique_ptr factory
rgw_cksum: mark string transform accessors const
rgw_cksum: fixup unittest_rgw_chksum compilation--all existing tests pass
rgw_cksum: hook up put-object checksum workflow
tweaks to report on content checksum mismatch
rgw_cksum: match SDK as well as general checksum header
make it more efficient
initialize RGWPutObj_Cksum::digest
rgw_cksum: write parse_cksum_type w/const char* arg
initialize _type correctly; doing armored wrong
fix expected checksum header name, clean up verify
fix output on checksum verify fail, cleanup
introduce Cksum::to_armor(); all AWS cases pass
oops, extra 0-byte at end of to_armor() result
