+Version 1.1pre14 is compatible with 1.0pre8, 1.0 and later, but not with older
versions of tinc.
-When the ExperimentalProtocol option is used, which is the default since

Requirements
In order to compile tinc, you will need a GNU C compiler environment. Please
ensure you have the latest stable versions of all the required libraries:
-- OpenSSL (http://www.openssl.org/) version 1.0.0 or later, with support for
- elliptic curve cryptography (ECC) enabeld.
+- LibreSSL (http://www.libressl.org/) or OpenSSL (https://openssl.org/) version 1.0.0 or later.
The following libraries are used by default, but can be disabled if necessary:
-- zlib (http://www.gzip.org/zlib/)
-- lzo (http://www.oberhumer.com/opensource/lzo/)
+- zlib (http://www.zlib.net/)
+- LZO (https://www.oberhumer.com/opensource/lzo/)
- ncurses (http://invisible-island.net/ncurses/)
-- readline (ftp://ftp.gnu.org/pub/gnu/readline/)

Features
connections automatically. When direct connections are not possible, data will
be forwarded by intermediate nodes.
-By default, nodes authenticate each other using 2048 bit RSA (or 521 bit
-ECDSA*) keys. Traffic is encrypted using Blowfish in CBC mode (or AES-256 in
-CTR mode*), authenticated using HMAC-SHA1 (or HMAC-SHA-256*), and is protected
-against replay attacks.
-
-*) When using the ExperimentalProtocol option.
+Tinc 1.1 support two protocols. The first is a legacy protocol that provides
+backwards compatibility with tinc 1.0 nodes, and which by default uses 2048 bit
+RSA keys for authentication, and encrypts traffic using Blowfish in CBC mode
+and HMAC-SHA1. The second is a new protocol which uses Curve25519 keys for
+authentication, and encrypts traffic using Chacha20-Poly1305, and provides
+forward secrecy.
Tinc fully supports IPv6.
Ethernet network switch or hub.
Normally, when started tinc will detach and run in the background. In a native

+Windows environment this means tinc will install itself as a service, which will
restart after reboots. To prevent tinc from detaching or running as a service,
use the -D option.
