SigmaVPN is light-weight, fast and secure VPN software. It uses advanced elliptic curve public key cryptography to establish encrypted IP tunnels with QuickTun or SigmaVPN endpoints.
- IPv4 and IPv6 tunnel support
- Supports nacl0 and nacltai (TAI64 nonce for extra security) encryption schemes
- Seamless handover between WiFi and GSM/3G
- Built-in key generation
As the first Google Play app to make use of the new Android VPN APIs, SigmaVPN requires Android 4.0 (Ice Cream Sandwich) in order to function.
Fixed an issue with the TAI64 encryption protocol that resulted in decryption errors with certain key pairs
