8 Diffie-Hellman public keys are encoded with Elligator algorithm when
9 sending over the wire, making them indistinguishable from the random
10 strings, preventing detection of successful decryption try when guessing
11 passwords (that are used to create DSA public keys). But this will
12 consume twice entropy for DH key generation in average.
18 EKE protocol is replaced by Augmented-EKE and static symmetric (both
19 sides have it) pre-shared key replaced with server-side verifier. This
20 requires, 64 more bytes in handshake traffic, Ed25519 dependency with
21 corresponding sign/verify computations, PBKDF2 dependency and its
22 usage on the client side during handshake.
24 A-EKE with PBKDF2-based verifiers is resistant to dictionary attacks,
25 can use human memorable passphrases instead of static keys and
26 server-side verifiers can not be used for authentication (compromised
27 server does not leak client's authentication keys/passphrases).
30 Changed transport message structure: added payload packet's length.
31 This will increase transport overhead for two bytes, but heartbeat
32 packets became smaller
35 Ability to hide underlying packets lengths by appending noise, junk
36 data during transmission. Each packet can be fill up-ed to its
40 Ability to hide underlying packets appearance rate, by generating
41 Constant Packet Rate traffic. This includes noise generation too.
43 Per-peer @code{-timeout}, @code{-noncediff}, @code{-noise} and
44 @code{-cpr} configuration options for server.
50 Added ability to optionally run built-in HTTP-server responding with
51 JSON of all known connected peers information. Real-time client's
55 Documentation is explicitly licensed under GNU FDL 1.3+.
61 Handshake packets became indistinguishable from the random.
62 Now all GoVPN's traffic is the noise for men in the middle.
65 Handshake messages are smaller (16% traffic reduce).
68 Adversary now can not create malicious fake handshake packets that
69 will force server to generate private DH key, preventing entropy
70 consuming and resource heavy computations.
