Constructor Detail

CertPathValidator

protected CertPathValidator(CertPathValidatorSpi validatorSpi,
                            Provider provider,
                            String algorithm)

Creates a new CertPathValidator instance.

Parameters:

validatorSpi - the implementation delegate.

provider - the security provider.

algorithm - the name of the algorithm.

Method Detail

getAlgorithm

public final String getAlgorithm()

Returns the certification path algorithm name.

Returns:

the certification path algorithm name.

getProvider

public final Provider getProvider()

Returns the security provider.

Returns:

the provider.

getInstance

public static CertPathValidator getInstance(String algorithm)
                                     throws NoSuchAlgorithmException

Returns a new certification path validator for the specified algorithm.

Parameters:

algorithm - the algorithm name.

Returns:

a certification path validator for the requested algorithm.

Throws:

NoSuchAlgorithmException - if no installed provider provides the specified algorithm.

NullPointerException - if algorithm is null.

getInstance

public static CertPathValidator getInstance(String algorithm,
                                            String provider)
                                     throws NoSuchAlgorithmException,
                                            NoSuchProviderException

Returns a new certification path validator for the specified algorithm from the specified provider.

Parameters:

algorithm - the algorithm name.

provider - the security provider name.

Returns:

a certification path validator for the requested algorithm.

Throws:

NoSuchAlgorithmException - if the specified security provider cannot provide the requested algorithm.

NoSuchProviderException - if no provider with the specified name can be found.

NullPointerException - if algorithm is null.

IllegalArgumentException - if provider == null || provider.isEmpty()

getInstance

public static CertPathValidator getInstance(String algorithm,
                                            Provider provider)
                                     throws NoSuchAlgorithmException

Returns a new certification path validator for the specified algorithm from the specified provider. The provider supplied does not have to be registered.

Parameters:

algorithm - the algorithm name.

provider - the security provider name.

Returns:

a certification path validator for the requested algorithm.

Throws:

NoSuchAlgorithmException - if the specified provider cannot provide the requested algorithm.

IllegalArgumentException - if provider == null

NullPointerException - if algorithm is null.

validate

public final CertPathValidatorResult validate(CertPath certPath,
                                              CertPathParameters params)
                                       throws CertPathValidatorException,
                                              InvalidAlgorithmParameterException

Validates the CertPath with the algorithm of this CertPathValidator using the specified algorithm parameters.

Parameters:

certPath - the certification path to be validated.

params - the certification path validator algorithm parameters.

Returns:

the validation result.

Throws:

CertPathValidatorException - if the validation fails, or the algorithm of the specified certification path cannot be validated using the algorithm of this instance.
