### Raw format
All documents in raw format are explained via a [PEG grammar].
The raw format is a plain text format used to sign a document or verify its signature.
Only documents whose signature must be verifiable by a client software are signed in this way. This applies in particular to peer cards and HEADs.
WS2pV2 messages are signed in binary format.
The PEG grammars of raw formats are presented according to the [pest syntax] (a particular implementation of PEG).

### Documents messages ### Documents messages
All WS2Pv2 documents are necessarily in Binary Format. When document binarization is coded in Duniter-ts, then it will be necessary to define a common binary format for each document. For performance reasons, we will probably opt for the format in which each document is signed. All WS2Pv2 documents are necessarily in Binary Format.
