# Which issue does this PR close? Closes #. # Rationale for this change S3 supports several checksum algorithms for verifying upload integrity (e.g. for buckets with Object Lock). OpenDAL's S3 service already supports `crc32c` and `md5`, but not `sha256`, which is one of the most commonly used and is accepted by S3 for both single and multipart uploads. # What changes are included in this PR? - Add a `Sha256` variant to the internal `ChecksumAlgorithm` enum, mapping to the `x-amz-checksum-sha256` header. - Compute the base64-encoded SHA256 digest of the body via a new `format_sha256_iter` helper (using the `sha2` crate) in `calculate_checksum`. - Accept `"sha256"` for the `checksum_algorithm` config / builder option. - Send the per-part `ChecksumSHA256` element when completing multipart uploads. - Add a unit test guarding the SHA256 digest output and update docs. # Are there any user-facing changes? Yes. `"sha256"` is now a valid value for the S3 `checksum_algorithm` option. Builder and config docs are updated. No breaking changes. # AI Usage Statement This PR was prepared with the assistance of Claude Code (Claude Opus 4.8).
