private org.slf4j.Logger	log Logger.
private ParserPool	parser Parser pool to use to process KeyInfo request parameter.

Constructor Summary

SAML2HTTPPostSimpleSignRule(SignatureTrustEngine engine, ParserPool parserPool, KeyInfoCredentialResolver keyInfoCredResolver)
Constructor.

Method Summary

protected List<Credential>	getRequestCredentials(javax.servlet.http.HttpServletRequest request, SAMLMessageContext samlContext) Extract any candidate validation credentials from the request and/or message context.
protected byte[]	getSignedContent(javax.servlet.http.HttpServletRequest request) Get the content over which to validate the signature, in the form suitable for input into SignatureTrustEngine.validate(byte[], byte[], String, CriteriaSet, Credential).
protected boolean	ruleHandles(javax.servlet.http.HttpServletRequest request, SAMLMessageContext samlMsgCtx) Determine whether the rule should handle the request, based on the unwrapped HTTP servlet request and/or message context.

Constructor Detail

SAML2HTTPPostSimpleSignRule

public SAML2HTTPPostSimpleSignRule(SignatureTrustEngine engine,
                                   ParserPool parserPool,
                                   KeyInfoCredentialResolver keyInfoCredResolver)

Constructor.

Parameters:

engine - the trust engine to use

parserPool - the parser pool used to parse the KeyInfo request parameter

keyInfoCredResolver - the KeyInfo credential resovler to use to extract credentials from the KeyInfo request parameter

Method Detail

ruleHandles

protected boolean ruleHandles(javax.servlet.http.HttpServletRequest request,
                              SAMLMessageContext samlMsgCtx)

Determine whether the rule should handle the request, based on the unwrapped HTTP servlet request and/or message context.

Specified by:

ruleHandles in class BaseSAMLSimpleSignatureSecurityPolicyRule

Parameters:

request - the HTTP servlet request being processed

samlMsgCtx - the SAML message context being processed

Returns:

true if the rule should attempt to process the request, otherwise false

getSignedContent

protected byte[] getSignedContent(javax.servlet.http.HttpServletRequest request)
                           throws SecurityPolicyException

Get the content over which to validate the signature, in the form suitable for input into SignatureTrustEngine.validate(byte[], byte[], String, CriteriaSet, Credential).

Specified by:

getSignedContent in class BaseSAMLSimpleSignatureSecurityPolicyRule

Parameters:

request - the HTTP servlet request being processed

Returns:

the signed content extracted from the request, in the format suitable for input to the trust engine.

Throws:

SecurityPolicyException - thrown if there is an error during request processing

getRequestCredentials

protected List<Credential> getRequestCredentials(javax.servlet.http.HttpServletRequest request,
                                                 SAMLMessageContext samlContext)
                                          throws SecurityPolicyException

Extract any candidate validation credentials from the request and/or message context. Some bindings allow validataion keys for the simple signature to be supplied, and others do not.

Overrides:

getRequestCredentials in class BaseSAMLSimpleSignatureSecurityPolicyRule

Parameters:

request - the HTTP servlet request being processed

samlContext - the SAML message context being processed

Returns:

a list of candidate validation credentials in the request, or null if none were present

Throws:

SecurityPolicyException - thrown if there is an error during request processing
