After updating c2patool from 0.18.4 to 0.20.3 our new signed images get error on https://contentcredentials.org/verify: This file may have been tampered with. Its Content Credentials can’t be verified or viewed.

The manifest is slightly different after invoking command:
bin/c2pa/c2patool flower.jpg -o flower_signed.jpg --config '{"alg":"ES256","vendor":"smartframe","private_key":"\/application\/bin\/c2pa\/test\/c2pa-private.key","sign_cert":"\/application\/bin\/c2pa\/test\/c2pa-certificate.pem","ta_url":"http:\/\/timestamp.digicert.com","claim_version":2,"claim_generator":"SmartFrame_Image_Cloud\/1.0.0"}' -f

Please verify if it's problem with verify site or we should change the way we sign images

[michalkorotkiewicz]

Please look into images I have problem with:

I am having the same issue on images generated with the OpenAI gpt-image-1 model.

Last week, all my generated images were showing the metadata on the verify site. The same images no longer show the metadata on the verify website.

To ensure I did not modify them, I checked the same images on https://29a.ch/photo-forensics/#c2pa and they properly show the metadata.

[emensch]

@michalkorotkiewicz we've made some updates recently. Can you check your images again and let me know if the problem persists?

@pdeitel can you share one of the problem images?

[pdeitel]

I literally checked this image a few minutes ago -- I generated this from a photo of mine with style transfer from another image.

When I check this with the verify site, I get "This file may have been tampered with. Its Content Credentials can’t be verified or viewed."

When I check it at https://29a.ch/photo-forensics/#c2pa, I get the following metadata:

@emensch I've tested with c2patool 0.22.1, and here are the results:

• New images with CC signed are fine—thanks for that.
• Images without CC signed are fine.
• Old images with CC signed have invalid history. Still get: This file may have been tampered with. Its Content Credentials can’t be verified or viewed.

Here is example with CC image: https://smartframe-static-staging.s3.eu-west-1.amazonaws.com/c2pa/verify-site_issues_316/test_with_cc.jpg
