DefaultSAML20AssertionValidationContextBuilder

public DefaultSAML20AssertionValidationContextBuilder()

Constructor.

Method Detail

isSignatureRequired

public boolean isSignatureRequired()

Get the flag indicating whether an Assertion signature is required.

Defaults to: true.

Returns:

true if required, false if not

setSignatureRequired

public void setSignatureRequired(boolean flag)

Set the flag indicating whether an Assertion signature is required.

Defaults to: true.

Parameters:

flag - true if required, false if not

getSignatureCriteriaSetFunction

@Nullable
public com.google.common.base.Function<Pair<org.opensaml.messaging.context.MessageContext,Assertion>,CriteriaSet> getSignatureCriteriaSetFunction()

Get the function for resolving the signature validation CriteriaSet for a particular function.

Defaults to: null.

Returns:

a criteria set instance, or null

setSignatureCriteriaSetFunction

public void setSignatureCriteriaSetFunction(@Nullable
                                            com.google.common.base.Function<Pair<org.opensaml.messaging.context.MessageContext,Assertion>,CriteriaSet> function)

Set the function for resolving the signature validation CriteriaSet for a particular function.

Defaults to: null.

Parameters:

function - the resolving function, may be null

apply

@Nullable
public ValidationContext apply(@Nullable
                                         SAML20AssertionTokenValidationInput input)

Specified by:

apply in interface com.google.common.base.Function<SAML20AssertionTokenValidationInput,ValidationContext>

buildStaticParameters

@Nonnull
protected Map<String,Object> buildStaticParameters(@Nonnull
                                                            SAML20AssertionTokenValidationInput input)

Build the static parameters map for input to the ValidationContext.

Parameters:

input - the assertion validation input

Returns:

the static parameters map

getSignatureCriteriaSet

@Nonnull
protected CriteriaSet getSignatureCriteriaSet(@Nonnull
                                                       SAML20AssertionTokenValidationInput input)

Get the signature validation criteria set.

This implementation first evaluates the result of applying the function getSignatureCriteriaSetFunction(), if configured. If that evaluation did not produce an EntityIdCriterion, one is added based on the issuer of the Assertion. If that evaluation did not produce an instance of UsageCriterion, one is added with the value of UsageType.SIGNING.

Parameters:

input - the assertion validation input

Returns:

the criteria set based on the message context data

getAttesterCertificate

@Nullable
protected X509Certificate getAttesterCertificate(@Nonnull
                                                           SAML20AssertionTokenValidationInput input)

Get the attesting entity's X509Certificate.

This implementation returns the client TLS certificate present in the HttpServletRequest, or null if one is not present.

Parameters:

input - the assertion validation input

Returns:

the entity certificate, or null

getAttesterPublicKey

@Nullable
protected PublicKey getAttesterPublicKey(@Nonnull
                                                   SAML20AssertionTokenValidationInput input)

Get the attesting entity's PublicKey.

This implementation returns null. Subclasses should override to implement specific logic.

Parameters:

input - the assertion validation input

Returns:

the entity public key, or null

getValidRecipients

@Nonnull
protected Set<String> getValidRecipients(@Nonnull
                                                  SAML20AssertionTokenValidationInput input)

Get the valid recipient endpoints for attestation.

This implementation returns a set containing the 2 values;

1. HttpServletRequest.getRequestURL()
2. if present, AbstractSAMLEntityContext.getEntityId()

Parameters:

input - the assertion validation input

Returns:

set of recipient endpoint URI's

getValidAddresses

@Nonnull
protected Set<InetAddress> getValidAddresses(@Nonnull
                                                      SAML20AssertionTokenValidationInput input)

Get the set of addresses which are valid for subject confirmation.

This implementation simply returns the set based on getAttesterIPAddress(SAML20AssertionTokenValidationInput), if that produces a value. Otherwise an empty set is returned.

Parameters:

input - the assertion validation input

Returns:

the set of valid addresses

getAttesterIPAddress

@Nonnull
protected String getAttesterIPAddress(@Nonnull
                                               SAML20AssertionTokenValidationInput input)

Get the attester's IP address.

This implementation returns the value of ServletRequest.getRemoteAddr().

Parameters:

input - the assertion validation input

Returns:

the IP address of the attester

getValidAudiences

@Nonnull
protected Set<String> getValidAudiences(@Nonnull
                                                 SAML20AssertionTokenValidationInput input)

Get the valid audiences for attestation.

This implementation returns a set containing the single entityID held by the message context's AbstractSAMLEntityContext.getEntityId(), if present. Otherwise an empty set is returned.

Parameters:

input - the assertion validation input

Returns:

set of audience URI's
