1b9d47735c Optionally don't store client's cipher list.
This change causes the client's list of ciphers to be freed as soon as
we have sent a server-hello. This saves small, but useful, amount of
memory.

0b5c1ac8ad TLS 1.1 ciphers.
This patch adds support for a different cipher list when the connection
is using TLS 1.1. This is intended to support the case where we want to
use AES with >= TLS 1.1 clients but RC4 otherwise because of the BEAST
attack.

acff73f227 Constant-time, RSA PMS processing.
This change alters the processing of invalid, RSA pre-master secrets so
that bad encryptions are treated like random session keys in constant
time.

4d4bff89bb Cipher family functions.
This change adds functions to check membership of various cipher
families. Clients and servers need this in order to optimise the size of
records because different families have different amounts of prefix and
postfix overhead.

adb739e1e5 False Start support.
(Called "cut through" for historical reasons in this patch.)

Enables SSL3+ clients to send application data immediately following the
Finished message even when negotiating full-handshakes.  With this
patch, clients can negotiate SSL connections in 1-RTT even when
performing full-handshakes.

Initial fork from f2d678e6e89b6508147086610e985d4e8416e867 (1.0.2 beta).

(This change contains substantial changes from the original and
effectively starts a new history.)
