dfuse Opaque library

Encrypt plaintexts for simple obfuscation, like database cursors. It is used in dfuse.

Usage

Encode a proto message into an opaque element:

	cursor := pb.Cursor{Id: "123"}
	payload, err := proto.Marshal(&cursor)
	if err != nil { panic(err) }

	out := opaque.Encode(payload)
    // out == "xE77fJ_z6Z7UXwyx-e0kWqTtdc4yRR8vAEnvaUQSx96y"

Decode opaque element into a proto message:

	payload, err := opaque.Decode("xE77fJ_z6Z7UXwyx-e0kWqTtdc4yRR8vAEnvaUQSx96y")
	if err != nil { panic(fmt.Errorf("invalid cursor: %w", err)) }

	cursor := pb.Cursor{}
    err := proto.Unmarshal(payload, &cursor)
	if err != nil { panic(err) }

    // out == pb.Cursor{Id: "123"}
