, which of the below mentioned statements is true?
The user should use the same encryption key for all versions of the same object
It is possible to have different encryption keys for different versions of the same object
AWS S3 does not allow the user to upload his own keys for server side encryption
The SSE-C does not work when versioning is enabled
Explanations:
When using SSE-C, the user can use different encryption keys for different versions of the same object. There is no requirement to use the same encryption key for different versions.
SSE-C allows using different encryption keys for different versions of the same object. Each version of the object can be encrypted with a different key.
AWS S3 allows the user to upload their own encryption keys (SSE-C). It does not require AWS-managed keys (SSE-S3) or KMS keys (SSE-KMS).
SSE-C works with versioning enabled. It does not have a limitation with versioned objects in S3, and the user can upload multiple versions of the object encrypted with their own keys.
If memory serves me right, the answer is:
It is possible to have different encryption keys for different versions of the same object
