// General code cleanup and reorganization.  The signed ElGamal public key
// was moved to CODEX_Server, decoupling that package from CODEX_Client.
// Since CODEX_Server no longer knows about the cryptosystem used by
// the client, switching between cryptosystems is handled locally by
// CODEX_KeyService.
