TLS payload ciphertext (n bytes) (only for P_CONTROL_V1). Note that when –tls-auth is used, all message types are protected with an HMAC signature, even the initial packets of the TLS handshake. This makes it easy for OpenVPN to throw away bogus packets quickly, without wasting resources on attempting a TLS handshake which will ultimately fail.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm in the middle of re-configuring my OpenVPN (which died due to a server crash). I have the Server configured and all the certs/keys built for my clients. I have successfully set up a tunnel between the server and my DD-WRT enabled router, a Linksys NSLU2 and also a VPS.

Jul 24, 2014 · If --key-method 1 is used, the keys are generated directly from the OpenSSL RAND_bytes function. --key-method 2 was introduced with OpenVPN 1.5.0 and will be made the default in OpenVPN 2.0. During SSL/TLS rekeying, there is a transition-window parameter that permits overlap between old and new key usage, so there is no time pressure or latency

Added new packet format P_DATA_V2, which includes peer-id. If server supports, client sends all data packets in the new format. When data packet arrives, server identifies peer by peer-id.
