## Detailed Description

A trust engine that uses X.509 trust anchors and CRLs associated with a peer to perform PKIX validation of signatures and credentials.

## Constructor & Destructor Documentation

## AbstractPKIXTrustEngine()

xmltooling::AbstractPKIXTrustEngine::AbstractPKIXTrustEngine | ( | const xercesc::DOMElement * | e = 0,
|  | bool | deprecationSupport = true )

protected

Constructor.

If a DOM is supplied, the following XML content is supported:

- checkRevocation attribute (off, entityOnly, fullChain)
- policyMappingInhibit attribute (boolean)
- anyPolicyInhibit attribute (boolean)
- <PathValidator> element (zero or more)
- <TrustedName> element (zero or more)
- <PolicyOID> element (zero or more)

Parameters

  e | DOM to supply configuration for provider
  deprecationSupport | true iff deprecated features and settings should be supported

## Member Function Documentation

## checkEntityNames()

virtual bool xmltooling::AbstractPKIXTrustEngine::checkEntityNames | ( | X509 * | certEE,
|  | const CredentialResolver & | credResolver,
|  | const CredentialCriteria & | criteria ) const

protected virtual

Checks that either the name of the peer with the given credentials or the names of the credentials match the subject or subject alternate names of the certificate.

Alternatively explicit trusted names can be supplied statically via configuration.

Parameters

  certEE | the credential for the entity to validate
  credResolver | source of trusted credentials
  criteria | criteria for selecting credentials, including the peer name

Returns
  true the name check succeeds, false if not

## getPKIXValidationInfoIterator()

virtual PKIXValidationInfoIterator * xmltooling::AbstractPKIXTrustEngine::getPKIXValidationInfoIterator | ( | const CredentialResolver & | pkixSource,
|  | CredentialCriteria * | criteria = 0 ) const

pure virtual

Provides access to the information necessary, for the given credential source, for PKIX validation of credentials.

Each set of validation information returned will be tried, in turn, until one succeeds or no more remain. The caller must free the returned interface when finished with it.

Parameters

  pkixSource | the peer for which validation rules are required
  criteria | criteria for selecting validation rules

Returns
  interface for obtaining validation data

## validate() [1/4]

bool xmltooling::AbstractPKIXTrustEngine::validate | ( | const XMLCh * | sigAlgorithm,
|  | const char * | sig,
|  | xmlsignature::KeyInfo * | keyInfo,
|  | const char * | in,
|  | unsigned int | in_len,
|  | const CredentialResolver & | credResolver,
|  | CredentialCriteria * | criteria = 0 ) const

virtual

Determines whether a raw signature is correct and valid with respect to the source of credentials supplied.

It is the responsibility of the application to ensure that the Credentials supplied are in fact associated with the peer who created the signature.

If criteria with a peer name are supplied, the "name" of the Credential that verifies the signature may also be checked to ensure that it identifies the intended peer. The peer name itself or implementation-specific rules based on the content of the peer credentials may be applied. Implementations may omit this check if they deem it unnecessary.

Note that the keyInfo parameter is not part of the implicitly trusted set of information supplied via the CredentialResolver, but rather advisory data that may have accompanied the signature itself.

Parameters

  sigAlgorithm | XML Signature identifier for the algorithm used
  sig | null-terminated base64-encoded signature value
  keyInfo | KeyInfo object accompanying the signature, if any
  in | the input data over which the signature was created
  in_len | size of input data in bytes
  credResolver | a locked resolver to supply trusted peer credentials to the TrustEngine
  criteria | criteria for selecting peer credentials

Returns
  true iff the signature validates

Implements xmltooling::SignatureTrustEngine.

## validate() [2/4]

bool xmltooling::AbstractPKIXTrustEngine::validate | ( | X509 * | certEE,
|  | STACK_OF(X509) * | certChain,
|  | const CredentialResolver & | credResolver,
|  | CredentialCriteria * | criteria = 0 ) const

virtual

Determines whether an X.509 credential is valid with respect to the source of credentials supplied.

It is the responsibility of the application to ensure that the credentials supplied are in fact associated with the peer who presented the credential.

If criteria with a peer name are supplied, the "name" of the EE certificate may also be checked to ensure that it identifies the intended peer. The peer name itself or implementation-specific rules based on the content of the peer credentials may be applied. Implementations may omit this check if they deem it unnecessary.

Parameters

  certEE | end-entity certificate to validate
  certChain | the complete set of certificates presented for validation (includes certEE)
  credResolver | a locked resolver to supply trusted peer credentials to the TrustEngine
  criteria | criteria for selecting peer credentials

Implements xmltooling::OpenSSLTrustEngine.

## validate() [3/4]

bool xmltooling::AbstractPKIXTrustEngine::validate | ( | xmlsignature::Signature & | sig,
|  | const CredentialResolver & | credResolver,
|  | CredentialCriteria * | criteria = 0 ) const

virtual

Determines whether an XML signature is correct and valid with respect to the source of credentials supplied.

It is the responsibility of the application to ensure that the credentials supplied are in fact associated with the peer who created the signature.

If criteria with a peer name are supplied, the "name" of the Credential that verifies the signature may also be checked to ensure that it identifies the intended peer. The peer name itself or implementation-specific rules based on the content of the peer credentials may be applied. Implementations may omit this check if they deem it unnecessary.

Parameters

  sig | reference to a signature object to validate
  credResolver | a locked resolver to supply trusted peer credentials to the TrustEngine
  criteria | criteria for selecting peer credentials

Returns
  true iff the signature validates

Implements xmltooling::SignatureTrustEngine.

## validate() [4/4]

bool xmltooling::AbstractPKIXTrustEngine::validate | ( | XSECCryptoX509 * | certEE,
|  | const std::vector< XSECCryptoX509 * > & | certChain,
|  | const CredentialResolver & | credResolver,
|  | CredentialCriteria * | criteria = 0 ) const

virtual

Determines whether an X.509 credential is valid with respect to the source of credentials supplied.

It is the responsibility of the application to ensure that the credentials supplied are in fact associated with the peer who presented the credential.

If criteria with a peer name are supplied, the "name" of the EE certificate may also be checked to ensure that it identifies the intended peer. The peer name itself or implementation-specific rules based on the content of the peer credentials may be applied. Implementations may omit this check if they deem it unnecessary.

Parameters

  certEE | end-entity certificate to validate
  certChain | the complete set of certificates presented for validation (includes certEE)
  credResolver | a locked resolver to supply trusted peer credentials to the TrustEngine
  criteria | criteria for selecting peer credentials

Implements xmltooling::X509TrustEngine.
