NoSuchAlgorithmExceptions. Key generation is *slow* - I guess that's a
good sign. ;-)

CryptoModule with provider methods.

consist of independently encrypted and authenticated packets (Ack,
Batch, Subscriptions and Transports so far).

depending on the value of the first byte, so that an object's initial
tag is included in the data seen by the ObjectReader. Digests and
signatures can therefore be calculated over objects by their readers
without any risk of ambiguity.

authentication will make them redundant.

expected type, and re-throw as FormatException.

for easier testing.

by registering ObjectReaders with the Reader.

Defined some user-defined tags for protocol elements. Currently they're just adding redundancy, but in future they'll be used for parsing nested elements.

A more efficient encoding for short strings, raws, lists and maps. Now we can encode a list of three small integers in 4 bytes like MessagePack does, should that ever turn out to be useful.

Java 1.5 compatibility changes (for OSX 10.4). We depend on commons-io for a single method... might be worth copying the source into FileUtils if the license permits.

Don't store subscription or transport updates that are older than those already received. Also some small changes to DatabaseComponent impls for readability.

Retrieve messages from the database in raw form to avoid creating unnecessary short-lived objects. Added timestamps to headers.

New retransmission mechanism, which does away with the need for bundle IDs and should cope better with high bandwidth-delay product links.

Rewrote the bundle reading and writing code to eliminate copying. Signatures and digests are now calculated on the fly as the data is read or written. This is a little bit tricky in the case of reading because ReaderImpl uses a lookahead byte, so the signature and message digest need to lag one byte behind.
