8 @item Compatibility with an old GNU Make 3.x. Previously only BSD Make
9 and GNU Make 4.x were supported.
10 @item /dev/urandom is used for correct client identity generation under
11 GNU/Linux systems. Previously /dev/random can produce less than required
13 @item Updated user manual examples.
19 Deterministic building: dependent libraries source code commits are
20 fixed in our makefiles.
22 No Internet connection is needed for building the source code: all
23 required libraries are included in release tarballs.
25 FreeBSD Make compatibility. GNU Make is not necessary anymore.
31 Diffie-Hellman public keys are encoded with Elligator algorithm when
32 sending over the wire, making them indistinguishable from the random
33 strings, preventing detection of successful decryption try when guessing
34 passwords (that are used to create DSA public keys). But this will
35 consume twice entropy for DH key generation in average.
41 EKE protocol is replaced by Augmented-EKE and static symmetric (both
42 sides have it) pre-shared key replaced with server-side verifier. This
43 requires, 64 more bytes in handshake traffic, Ed25519 dependency with
44 corresponding sign/verify computations, PBKDF2 dependency and its
45 usage on the client side during handshake.
47 A-EKE with PBKDF2-based verifiers is resistant to dictionary attacks,
48 can use human memorable passphrases instead of static keys and
49 server-side verifiers can not be used for authentication (compromised
50 server does not leak client's authentication keys/passphrases).
53 Changed transport message structure: added payload packet's length.
54 This will increase transport overhead for two bytes, but heartbeat
55 packets became smaller
58 Ability to hide underlying packets lengths by appending noise, junk
59 data during transmission. Each packet can be fill up-ed to its
63 Ability to hide underlying packets appearance rate, by generating
64 Constant Packet Rate traffic. This includes noise generation too.
66 Per-peer @code{-timeout}, @code{-noncediff}, @code{-noise} and
67 @code{-cpr} configuration options for server.
73 Added ability to optionally run built-in HTTP-server responding with
74 JSON of all known connected peers information. Real-time client's
78 Documentation is explicitly licensed under GNU FDL 1.3+.
84 Handshake packets became indistinguishable from the random.
85 Now all GoVPN's traffic is the noise for men in the middle.
88 Handshake messages are smaller (16% traffic reduce).
91 Adversary now can not create malicious fake handshake packets that
92 will force server to generate private DH key, preventing entropy
93 consuming and resource heavy computations.
