Detailed Description

Internal state for the Duplex key exchange (client-side).

This structure holds the state information required by a client participating in a Duplex key exchange. It includes:

keyid: A unique key identity string (of size QSMP_KEYID_SIZE) that identifies the key exchange session.
schash: A session token hash (of size QSMP_DUPLEX_SCHASH_SIZE) used to verify session integrity.
prikey: The client's asymmetric cipher private key (of size QSMP_ASYMMETRIC_PRIVATE_KEY_SIZE).
pubkey: The client's asymmetric cipher public key (of size QSMP_ASYMMETRIC_PUBLIC_KEY_SIZE).
rverkey: The remote party's asymmetric signature verification key (of size QSMP_ASYMMETRIC_VERIFY_KEY_SIZE).
sigkey: The client's asymmetric signature signing key (of size QSMP_ASYMMETRIC_SIGNING_KEY_SIZE).
ssec: The derived asymmetric shared secret (of size QSMP_SECRET_SIZE) computed during key exchange.
verkey: The client's local asymmetric signature verification key (of size QSMP_ASYMMETRIC_VERIFY_KEY_SIZE).
expiration: A timestamp (in seconds from the epoch) indicating when the key exchange session expires.
