Function SSECopy

pkg/encrypt/server-side.go:143–151

SSECopy transforms a SSE-C encryption into a SSE-C copy encryption. This is required for SSE-C key rotation or a SSE-C copy where the source and the destination should be encrypted. If the provided sse is no SSE-C encryption SSECopy returns sse unmodified.

(sse ServerSide)

// If the provided sse is no SSE-C encryption SSECopy returns
// sse unmodified.
func SSECopy(sse ServerSide) ServerSide {
	if sse == nil || sse.Type() != SSEC {
		return sse
	}
	if sse, ok := sse.(ssec); ok {
		return ssecCopy(sse)
	}
	return sse
}
