Object integrity how to verify?

https://www.reddit.com/r/storj/comments/1dfxciy/checksum_md5_of_3tb_file_without_downloading/

Is there any other way other than downloading the (huge) file?

You do not need to verify an integrity, because otherwise the file wouldn’t be possible to decrypt. It’s also wouldn’t be confirmed until uploaded.

However, you may request a metainformation of the object. If it was uploaded using S3, each such object has ETag with a checksum.

Using aws CLI:

aws s3api head-object --endpoint https://gateway.storjshare.io --key test/3TB.mp4 --bucket video

You would receive something like that:

{
    "AcceptRanges": "bytes",
    "LastModified": "2024-06-12T03:54:22+00:00",
    "ContentLength": 3298534883328,
    "ETag": "\"085c060e134663db10b91a9e9ccdb597\"",
    "ContentType": "application/octet-stream",
    "Metadata": {}
}

Using uplink CLI:

uplink meta get sj://video/test/3TB.mp4

would return something like that:

{
  "content-type": "application/octet-stream",
  "s3:etag": "085c060e134663db10b91a9e9ccdb597"
}

But it works only for objects uploaded via S3, not Storj native. At least now.
