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