-
VPN client exposes local Socks5 proxy
-
VPN client supports port tunneling
-
Deep Packet Inspection (DPI) resistant protocol: handshake and traffic is computationally indistinguishable from random data
-
Polymorphic protocol: random packet length, inter-arrival time and packets generation (noise)
-
Protocol masking: encrypted traffic can be wrapped up into HTTPS protocol to bypass some firewalls
-
Forward secrecy property
-
Low memory consumption: client - 32Mb, server - 256Mb
-
Cascade encryption scheme of 3 randomly selected ciphers.
-
Overall key size range is from 768 to 3328 bits.
-
Key exchange encryption cipher: 256-bit NTRU based on Skein-512
- One-time pad derived from Skein PRNG continuously seeded with Hardware RNG values
- Password derived from Skein PRNG or Lyra2
-
High-quality entropy gathered from Hardware RNG based on CPU timing jitter
-
Independent Skein PRNG based random generators for Nonce and Key
-
Random generators are seeded every second
-
