Using + NPN, the server offered a list of protocols it advertised, and then the + client chose its favorite. With ALPN the client offers a list of protocols + and the server chooses. Thus the signatures of both the TLS::Client and + TLS::Server constructors have changed. + * Optimized ECDSA signature verification thanks to an observation by Dr. Falko Strenzke. On some systems verifications are between 1.5 and 2 times faster than in 1.11.15. |
