8 @item Handshake messages can be noised: their messages lengths are
9 hidden. Now they are indistinguishable from transport messages.
10 @item Parallelized clients processing on the server side.
11 @item Much higher overall performance.
12 @item Single JSON file server configuration.
17 @item Ability to use @ref{Network, TCP} network transport.
18 Server can listen on both UDP and TCP sockets.
19 @item Ability to use @ref{Proxy, HTTP proxies} (through CONNECT method)
20 for accessing the server. Server can also emulate HTTP proxy behaviour.
21 @item Updated Poly1305 library with ARM-related bugfixes.
22 @item Go 1.5+ version is highly recommended because of performance
28 @item Ability to use external @ref{EGD}-compatible PRNGs. Now you are
29 able to use GoVPN even on systems with the bad @code{/dev/random},
30 providing higher quality entropy from external sources.
31 @item Removed @code{-noncediff} option. It is replaced with in-memory
32 storage of seen nonces, thus eliminating possible replay attacks at all
33 without performance degradation related to inbound packets reordering.
38 @item Compatibility with an old GNU Make 3.x. Previously only BSD Make
39 and GNU Make 4.x were supported.
40 @item /dev/urandom is used for correct client identity generation under
41 GNU/Linux systems. Previously /dev/random can produce less than required
43 @item Updated user manual examples.
49 Deterministic building: dependent libraries source code commits are
50 fixed in our makefiles.
52 No Internet connection is needed for building the source code: all
53 required libraries are included in release tarballs.
55 FreeBSD Make compatibility. GNU Make is not necessary anymore.
61 Diffie-Hellman public keys are encoded with Elligator algorithm when
62 sending over the wire, making them indistinguishable from the random
63 strings, preventing detection of successful decryption try when guessing
64 passwords (that are used to create DSA public keys). But this will
65 consume twice entropy for DH key generation in average.
71 EKE protocol is replaced by Augmented-EKE and static symmetric (both
72 sides have it) pre-shared key replaced with server-side verifier. This
73 requires, 64 more bytes in handshake traffic, Ed25519 dependency with
74 corresponding sign/verify computations, PBKDF2 dependency and its
75 usage on the client side during handshake.
77 A-EKE with PBKDF2-based verifiers is resistant to dictionary attacks,
78 can use human memorable passphrases instead of static keys and
79 server-side verifiers can not be used for authentication (compromised
80 server does not leak client's authentication keys/passphrases).
83 Changed transport message structure: added payload packet's length.
84 This will increase transport overhead for two bytes, but heartbeat
85 packets became smaller
88 Ability to hide underlying packets lengths by appending noise, junk
89 data during transmission. Each packet can be fill up-ed to its
93 Ability to hide underlying packets appearance rate, by generating
94 Constant Packet Rate traffic. This includes noise generation too.
96 Per-peer @code{-timeout}, @code{-noncediff}, @code{-noise} and
97 @code{-cpr} configuration options for server.
103 Added ability to optionally run built-in HTTP-server responding with
104 JSON of all known connected peers information. Real-time client's
108 Documentation is explicitly licenced under GNU FDL 1.3+.
114 Handshake packets became indistinguishable from the random.
115 Now all GoVPN's traffic is the noise for men in the middle.
118 Handshake messages are smaller (16% traffic reduce).
121 Adversary now can not create malicious fake handshake packets that
122 will force server to generate private DH key, preventing entropy
123 consuming and resource heavy computations.
