strongSwan VPN Client Key Features
- Uses the VpnService API featured by Android 4+. Devices by some manufacturers seem to lack support for this - strongSwan VPN Client won't work on these devices!
- Uses the IKEv2 key exchange protocol (IKEv1 is *not* supported)
- Uses IPsec for data traffic (L2TP is *not* supported)
- Full support for changed connectivity and mobility through MOBIKE (or reauthentication)
- Combined RSA/ECDSA and EAP authentication is supported by using two authentication rounds as defined in RFC 4739
- IKEv2 fragmentation is supported if the VPN server supports it (strongSwan does so since 5.2.1)
- Split-tunneling allows sending only certain traffic through the VPN and/or excluding specific traffic from it
- Per-app VPN allows limiting the VPN connection to specific apps, or exclude them from using it
- The IPsec implementation currently supports the AES-CBC, AES-GCM, ChaCha20/Poly1305 and SHA1/SHA2 algorithms
- Passwords are currently stored as cleartext in the database (only if stored with a profile)
- VPN profiles may be imported from files
- READ_EXTERNAL_STORAGE: Allows importing VPN profiles and CA certificates from external storage on some Android versions
- QUERY_ALL_PACKAGES: Required on Android 11+ to select apps to ex-/include in VPN profiles and the optional EAP-TNC use case
