// no way to verify this assumption since the encryption happens
// inside AWS S3.
// Therefore, S3 clients must not make any assumption about ETags
// in case of SSE-C or SSE-KMS except that the ETag is well-formed.
//
// To put all of this into a simple rule:
//
//	SSE-S3 : ETag == MD5
//	SSE-C  : ETag != MD5
//	SSE-KMS: ETag != MD5

// # Encrypted ETags

./mc mirror internal myminio/versioned/ --quiet >/dev/null
./mc mirror internal myminio/versioned-1/ --quiet >/dev/null

## Soft delete (creates delete markers)
./mc rm -r --force myminio/versioned >/dev/null
./mc rm -r --force myminio/versioned-1 >/dev/null

## mirror again to create another set of version on top
./mc mirror internal myminio/versioned/ --quiet >/dev/null

## Forbid Extra Headers

In some special use cases (probably not very common), you might want to **restrict** the headers that you want to receive.

You can use Pydantic's model configuration to `forbid` any `extra` fields:
