For our application, we chose a protobuf format without delimiting. We thought the EOF that would occur when reading the file would suffice. (For those interested: It's the Bitcoin wallet format for bitcoinj-based apps)
Now I'd like to wrap it in an encryption layer. Unfortunately, the encryption I want to use is a padding block cipher. That means after the encrypt/decrypt roundtrip you'll end up with zero bytes appended to the serialized protobuf. I know I could switch my serialization code to the readDelimitedFrom() and writeDelimitedTo() pair, but that would make the format incompatible due to the prepended varint length field. *Question:* Is it possible, either programmatically or by declaring it in the .proto file, that a zero tag ends the deserialization just like an EOF would do? -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.
