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