How to disable Content-MD5 header with S3 PutObject request

[vbrajyaguru]

Hello,

I'm looking for a way to disable content verification on uploads. I'm using PutObjectRequest and set ChecksumAlgorithm::NOT_SET but the request still generated content-md5 header.

Aws SDK 1.11.293
SLES 15 SP4

Currently there is no way to send a request without a checksum. If you want I can change this to a feature request? If we do make this a feature request I'm not sure when it would be completed.

Yes, please consider this as feature request. We are using S3 client and using PutObjectRequest to create the PUT request. Our application has its own checksumming method to verify data integrity of the object read from the S3. We don't need data integrity protection while uploading the object to S3 and so we need some way to tell S3 client to not perform checksumming on the content.

Let me know and I can provide code samples if needed.

are you using one of the algorithms currently provided by SDK (md5, crc32, crc32c, sha1 or sha256) for your own integrity verification solution? You could consider providing the value to SDK (that will avoid perfoming calculation on SDK side) as a work around for now.
