How to disable Content-MD5 header with S3 PutObject request

[jmklix]

Discussed in #2926

^{Originally posted by vbrajyaguru April 15, 2024}
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

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.

@jmklix any updates on this?

Sorry, but no updates as of now. It's still in our backlog

hey sorry for the delay, you can read about the changes in checksumming behavior in #3253

we also updated some documentation on how this can be achieved, please reference "An API that has checksum when supported and you wish to send no checksum at all with the request" section on how to disable object integrity checks all together, however it is not recommended.

resolving, let us know if you have any more questions.
