Detailed Description

Security parameter state for a single VPN tunnel.

An active VPN tunnel running with TLS enabled has one tls_multi object, in which it stores all control channel and data channel security parameter state. This structure can contain multiple, possibly simultaneously active, tls_context objects to allow for interruption-less transitions during session renegotiations. Each tls_context represents one control channel session, which can span multiple data channel security parameter sessions stored in key_state structures.

Field Documentation

◆ auth_token

char* tls_multi::auth_token

◆ auth_token_initial

char* tls_multi::auth_token_initial

The first auth-token we sent to a client.

We use this to remember the session ID and initial timestamp when generating new auth-token.
