In GCS I am trying to upload an encripted file and download using same customer encryption key.
That’s working just fine.

My code

The file is uploading (and downloading) in the bucket successfully but some metadata are missing in GCS bucket (see console) and also when trying to check it from my code.

I can see file size BUT I can’t check the crc32c and md5hash.

GCP Bucket Console

Prints

Bucket location is us_central

I need to use a customer KEY for files encryption and also use the crc32c in this project but can’t make it work.
Upload and download are working just fine.

I can’t find an example in the web how to work with customer supplied encryption key with crc32c metadata.

anyone can share some example code to correctly made this?

Or tell me if there is any missing bucket configuration or what I’m doing wrong..
