Builder

Builder

Builder(
    serverAddr: String, 
    identity: String)

Creates a new builder with the basic parameters of an IKEv2/IPsec VPN.
Requires the PackageManager#FEATURE_IPSEC_TUNNELS feature which can be detected using PackageManager.hasSystemFeature(String).

Builder

Builder(ikeTunConnParams: IkeTunnelConnectionParams)

Creates a new builder from a IkeTunnelConnectionParams
Requires the PackageManager#FEATURE_IPSEC_TUNNELS feature which can be detected using PackageManager.hasSystemFeature(String).

build

fun build(): Ikev2VpnProfile

Validates, builds and provisions the VpnProfile.
Requires the PackageManager#FEATURE_IPSEC_TUNNELS feature which can be detected using PackageManager.hasSystemFeature(String).

setAllowedAlgorithms

fun setAllowedAlgorithms(algorithmNames: MutableList<String!>): Ikev2VpnProfile.Builder

Sets the allowable set of IPsec algorithms

If set, this will constrain the set of algorithms that the IPsec tunnel will use for integrity verification and encryption to the provided list.

The set of allowed IPsec algorithms is defined in IpSecAlgorithm. Adding of algorithms that are considered insecure (such as AUTH_HMAC_MD5 and AUTH_HMAC_SHA1) is not permitted, and will result in an IllegalArgumentException being thrown.

The provided algorithm list must contain at least one algorithm that provides Authentication, and one that provides Encryption. Authenticated Encryption with Associated Data (AEAD) algorithms provide both Authentication and Encryption.

If this Builder is constructed with an IkeTunnelConnectionParams, authentication details should be configured there, and calling this method will result in an exception being thrown.

By default, this profile will use any algorithm defined in IpSecAlgorithm, with the exception of those considered insecure (as described above).
Requires the PackageManager#FEATURE_IPSEC_TUNNELS feature which can be detected using PackageManager.hasSystemFeature(String).

setAuthDigitalSignature

fun setAuthDigitalSignature(
    userCert: X509Certificate, 
    key: PrivateKey, 
    serverRootCa: X509Certificate?
): Ikev2VpnProfile.Builder

Set the IKEv2 authentication to use Digital Signature Authentication with the given key.

Setting this will configure IKEv2 authentication using a Digital Signature scheme. Only one authentication method may be set. This method will overwrite any previously set authentication method.

If this Builder is constructed with an IkeTunnelConnectionParams, authentication details should be configured there, and calling this method will result in an exception being thrown.
Requires the PackageManager#FEATURE_IPSEC_TUNNELS feature which can be detected using PackageManager.hasSystemFeature(String).

setAuthPsk

fun setAuthPsk(psk: ByteArray): Ikev2VpnProfile.Builder

Set the IKEv2 authentication to use Preshared keys.

Setting this will configure IKEv2 authentication using a Preshared Key. Only one authentication method may be set. This method will overwrite any previously set authentication method.

If this Builder is constructed with an IkeTunnelConnectionParams, authentication details should be configured there, and calling this method will result in an exception being thrown.
Requires the PackageManager#FEATURE_IPSEC_TUNNELS feature which can be detected using PackageManager.hasSystemFeature(String).

setAuthUsernamePassword

fun setAuthUsernamePassword(
    user: String, 
    pass: String, 
    serverRootCa: X509Certificate?
): Ikev2VpnProfile.Builder

Set the IKEv2 authentication to use the provided username/password.

Setting this will configure IKEv2 authentication using EAP-MSCHAPv2. Only one authentication method may be set. This method will overwrite any previously set authentication method.

If this Builder is constructed with an IkeTunnelConnectionParams, authentication details should be configured there, and calling this method will result in an exception being thrown.
Requires the PackageManager#FEATURE_IPSEC_TUNNELS feature which can be detected using PackageManager.hasSystemFeature(String).

setAutomaticIpVersionSelectionEnabled

fun setAutomaticIpVersionSelectionEnabled(isEnabled: Boolean): Ikev2VpnProfile.Builder

Sets the enabled state of the automatic IP version selection
Requires the PackageManager#FEATURE_IPSEC_TUNNELS feature which can be detected using PackageManager.hasSystemFeature(String).

setAutomaticNattKeepaliveTimerEnabled

fun setAutomaticNattKeepaliveTimerEnabled(isEnabled: Boolean): Ikev2VpnProfile.Builder

Sets the enabled state of the automatic NAT-T keepalive timers Note that if this builder was constructed with a IkeTunnelConnectionParams, but this is called with true, the framework will automatically choose the appropriate keepalive timer and ignore the settings in the session params embedded in the connection params.
Requires the PackageManager#FEATURE_IPSEC_TUNNELS feature which can be detected using PackageManager.hasSystemFeature(String).

setBypassable

fun setBypassable(isBypassable: Boolean): Ikev2VpnProfile.Builder

Sets whether apps can bypass this VPN connection.

By default, all traffic from apps are forwarded through the VPN interface and it is not possible for unprivileged apps to side-step the VPN. If a VPN is set to bypassable, apps may use methods such as Network#getSocketFactory or android.net.Network#openConnection to instead send/receive directly over the underlying network or any other network they have permissions for.
Requires the PackageManager#FEATURE_IPSEC_TUNNELS feature which can be detected using PackageManager.hasSystemFeature(String).

setLocalRoutesExcluded

fun setLocalRoutesExcluded(excludeLocalRoutes: Boolean): Ikev2VpnProfile.Builder

Sets whether the local traffic is exempted from the VPN. When this is set, the system will not use the VPN network when an app tries to send traffic for an IP address that is on a local network. Note that there are important security implications. In particular, the networks that the device connects to typically decides what IP addresses are part of the local network. This means that for VPNs setting this flag, it is possible for anybody to set up a public network in such a way that traffic to arbitrary IP addresses will bypass the VPN, including traffic to services like DNS. When using this API, please consider the security implications for your particular case. Note that because the local traffic will always bypass the VPN, it is not possible to set this flag on a non-bypassable VPN.
Requires the PackageManager#FEATURE_IPSEC_TUNNELS feature which can be detected using PackageManager.hasSystemFeature(String).

setMaxMtu

fun setMaxMtu(mtu: Int): Ikev2VpnProfile.Builder

Set the upper bound of the maximum transmission unit (MTU) of the VPN interface.

If it is not set, a safe value will be used. Additionally, the actual link MTU will be dynamically calculated/updated based on the underlying link's mtu.
Requires the PackageManager#FEATURE_IPSEC_TUNNELS feature which can be detected using PackageManager.hasSystemFeature(String).

setMetered

fun setMetered(isMetered: Boolean): Ikev2VpnProfile.Builder

Marks the VPN network as metered.

A VPN network is classified as metered when the user is sensitive to heavy data usage due to monetary costs and/or data limitations. In such cases, you should set this to true so that apps on the system can avoid doing large data transfers. Otherwise, set this to false. Doing so would cause VPN network to inherit its meteredness from the underlying network.
Requires the PackageManager#FEATURE_IPSEC_TUNNELS feature which can be detected using PackageManager.hasSystemFeature(String).

setProxy

fun setProxy(proxy: ProxyInfo?): Ikev2VpnProfile.Builder

Sets a proxy for the VPN network.

Note that this proxy is only a recommendation and it may be ignored by apps.
Requires the PackageManager#FEATURE_IPSEC_TUNNELS feature which can be detected using PackageManager.hasSystemFeature(String).

setRequiresInternetValidation

fun setRequiresInternetValidation(requiresInternetValidation: Boolean): Ikev2VpnProfile.Builder

Request that this VPN undergoes Internet validation. If this is true, the platform will perform basic validation checks for Internet connectivity over this VPN. If and when they succeed, the VPN network capabilities will reflect this by gaining the NetworkCapabilities#NET_CAPABILITY_VALIDATED capability. If this is false, the platform assumes the VPN either is always capable of reaching the Internet or intends not to. In this case, the VPN network capabilities will always gain the NetworkCapabilities#NET_CAPABILITY_VALIDATED capability immediately after it connects, whether it can reach public Internet destinations or not.
Requires the PackageManager#FEATURE_IPSEC_TUNNELS feature which can be detected using PackageManager.hasSystemFeature(String).
