Detailed Description

This namespace holds the class definitions for APSS.

Enumeration Type Documentation

enum CODEX_APSS::MessageType

Message types. Signed message types are not included. There are easily enough bits left over in a single byte for one-bit annotations. Definition at line 639 of file CODEX_APSS/Message.h.

---

Variable Documentation

const unsigned char CODEX_APSS::SignatureMask = 0x80

Bit 1 is set if the message is signed. This is assumed to be an RSA signature. Definition at line 657 of file CODEX_APSS/Message.h. Referenced by CODEX_APSS::InitActivity::addEvidence(), CODEX_APSS::SecretManagement::beginRun(), CODEX_APSS::MessageVerifier::handler(), CODEX_APSS::MessageProcessor::handler(), CODEX_APSS::InitActivity::handler(), CODEX_APSS::MessageParser::operator()(), CODEX_APSS::StateInfo::recover(), and CODEX_APSS::SecretManagement::sendFinished().
