Use only when it is not possible to configure the Root CA cert for the server.
Note: If a Root CA cert is already configured, this option is ignored, e.g. if setCaCertificate(java.security.cert.X509Certificate), or setCaCertificates(java.security.cert.X509Certificate[]) is called.

isServerCertValidationEnabled

Added in API level 31
public boolean isServerCertValidationEnabled ()

Determines whether an Enterprise configuration enables server certificate validation.

The caller can determine, along with isEapMethodServerCertUsed(), if an Enterprise configuration enables server certificate validation, which is a mandatory requirement for networks that use TLS based EAP methods. A configuration that does not enable server certificate validation will be ignored and will not be considered for network selection. A network suggestion with such a configuration will cause an IllegalArgumentException to be thrown when suggested. Server validation is achieved by the following: - Either certificate or CA path is configured. - Either alternative subject match or domain suffix match is set.

Returns
boolean True for server certificate validation is enabled, false otherwise.

Throws
IllegalStateException on configuration which doesn't use server certificate.

Set alternate subject match. This is the substring to be matched against the alternate subject of the authentication server certificate. Note: If no alternate subject is set for an Enterprise configuration, either by not calling this API, or by calling it with null, or not setting domain suffix match using the setDomainSuffixMatch(java.lang.String), then the server certificate validation is incomplete - which means that the connection is not secure.

Parameters
altSubjectMatch String: substring to be matched, for example DNS:server.example.com;EMAIL:[email protected]

setAnonymousIdentity

Added in API level 18
public void setAnonymousIdentity (String anonymousIdentity)

Set anonymous identity. This is used as the unencrypted identity with certain EAP types

Parameters
anonymousIdentity String: the anonymous identity

setCaCertificate

Added in API level 18
public void setCaCertificate (X509Certificate cert)

Specify a X.509 certificate that identifies the server.

A default name is automatically assigned to the certificate and used with this configuration. The framework takes care of installing the certificate when the config is saved and removing the certificate when the config is removed. Note: If no certificate is set for an Enterprise configuration, either by not calling this API (or the setCaCertificates(java.security.cert.X509Certificate[]), or by calling it with null, then the server certificate validation is skipped - which means that the connection is not secure.

Parameters
cert X509Certificate: X.509 CA certificate This value may be null.

Throws
IllegalArgumentException if not a CA certificate

setCaCertificates

Added in API level 24
public void setCaCertificates (X509Certificate[] certs)

Specify a list of X.509 certificates that identifies the server. The validation passes if the CA of server certificate matches one of the given certificates.

Default names are automatically assigned to the certificates and used with this configuration. The framework takes care of installing the certificates when the config is saved and removing the certificates when the config is removed. Note: If no certificates are set for an Enterprise configuration, either by not calling this API (or the setCaCertificate(java.security.cert.X509Certificate), or by calling it with null, then the server certificate validation is skipped - which means that the connection is not secure.

Parameters
certs X509Certificate: X.509 CA certificates This value may be null.

Throws
IllegalArgumentException if any of the provided certificates is not a CA certificate, or if too many CA certificates are provided

setClientKeyEntry

Added in API level 18
public void setClientKeyEntry (PrivateKey privateKey, 
                X509Certificate clientCertificate)

Specify a private key and client certificate for client authorization.

A default name is automatically assigned to the key entry and used with this configuration. The framework takes care of installing the key entry when the config is saved and removing the key entry when the config is removed.

Parameters
privateKey PrivateKey: a PrivateKey instance for the end certificate.

clientCertificate X509Certificate: an X509Certificate representing the end certificate.

Throws
IllegalArgumentException for an invalid key or certificate.

setClientKeyEntryWithCertificateChain

Added in API level 26
public void setClientKeyEntryWithCertificateChain (PrivateKey privateKey, 
                X509Certificate[] clientCertificateChain)

Specify a private key and client certificate chain for client authorization.

A default name is automatically assigned to the key entry and used with this configuration. The framework takes care of installing the key entry when the config is saved and removing the key entry when the config is removed.

Parameters
privateKey PrivateKey: a PrivateKey instance for the end certificate.

clientCertificateChain X509Certificate: an array of X509Certificate instances which starts with end certificate and continues with additional CA certificates necessary to link the end certificate with some root certificate known by the authenticator.

Throws
IllegalArgumentException for an invalid key or certificate.

setClientKeyPairAlias

Added in API level 31
public void setClientKeyPairAlias (String alias)

Specify a key pair via KeyChain alias for client authentication. The alias should refer to a key pair in KeyChain that is allowed for WiFi authentication.

Parameters
alias String: key pair alias This value cannot be null.

setDecoratedIdentityPrefix

Added in API level 31
public void setDecoratedIdentityPrefix (String decoratedIdentityPrefix)

Set a prefix for a decorated identity as per RFC 7542. This prefix must contain a list of realms (could be a list of 1) delimited by a '!' character. e.g. homerealm.example.org! or proxyrealm.example.net!homerealm.example.org! A prefix of "homerealm.example.org!" will generate a decorated identity that looks like: [email protected] Calling with a null parameter will clear the decorated prefix. Note: Caller must verify that the device supports this feature by calling WifiManager#isDecoratedIdentitySupported()

Parameters
decoratedIdentityPrefix String: The prefix to add to the outer/anonymous identity This value may be null.

setDomainSuffixMatch

Added in API level 23
public void setDomainSuffixMatch (String domain)

Set the domain_suffix_match directive on wpa_supplicant. This is the parameter to use for Hotspot 2.0 defined matching of AAA server certs per WFA HS2.0 spec, section 7.3.3.2, second paragraph.

From wpa_supplicant documentation:

Constraint for server domain name. If set, this FQDN is used as a suffix match requirement for the AAAserver certificate in SubjectAltName dNSName element(s). If a matching dNSName is found, this constraint is met.

Suffix match here means that the host/domain name is compared one label at a time starting from the top-level domain and all the labels in domain_suffix_match shall be included in the certificate. The certificate may include additional sub-level labels in addition to the required labels.

More than one match string can be provided by using semicolons to separate the strings (e.g., example.org;example.com). When multiple strings are specified, a match with any one of the values is considered a sufficient match for the certificate, i.e., the conditions are ORed ogether.

For example, domain_suffix_match=example.com would match test.example.com but would not match test-example.com. Note: If no domain suffix is set for an Enterprise configuration, either by not calling this API, or by calling it with null, or not setting alternate subject match using the setAltSubjectMatch(java.lang.String), then the server certificate validation is incomplete - which means that the connection is not secure.

Parameters
domain String: The domain value

setEapMethod

Added in API level 18
public void setEapMethod (int eapMethod)

Set the EAP authentication method.

Parameters
eapMethod int: is one of Eap, except for Eap#NONE

public void setMinimumTlsVersion (int tlsVersion)

Set the minimum TLS version for TLS-based EAP methods. WifiManager#isTlsMinimumVersionSupported() indicates whether or not a minimum TLS version can be set. If not supported, the minimum TLS version is always TLS v1.0.

WifiManager#isTlsV13Supported() indicates whether or not TLS v1.3 is supported. If requested minimum is not supported, it will default to the maximum supported version.

Parameters
tlsVersion int: the TLS version Value is TLS_V1_0, TLS_V1_1, TLS_V1_2, or TLS_V1_3
