Add checksums to pipe, cp, mirror commands. > Add checksum to uploaded object. Values: MD5, CRC32, CRC32C, SHA1 or SHA256. Requires server trailing headers support like AWS, MinIO and possibly others. `--md5` is hidden, but still applied. Uploads to buckets with object locking will still use MD5. Bonus: `mc stat` shows checksum information.
