Method Detail

getFreshness

public Duration getFreshness(ValidationContext validationContext)

Returns the freshness setting for the provided validation context or the default context in milliseconds.

Parameters:

validationContext - the validation context for which to retrieve the freshness setting

Returns:

the freshness setting for the provided validation context or the default context in milliseconds

setFreshness

public final SignatureValidationProperties setFreshness(ValidatorContexts validatorContexts,
                                                        CertificateSources certificateSources,
                                                        TimeBasedContexts timeBasedContexts,
                                                        Duration value)

Sets the freshness setting for the specified validator, time based and certificate source contexts in milliseconds.

This parameter specifies how old revocation data can be, compared to validation time, in order to be trustworthy.

Parameters:

validatorContexts - the validators for which to apply the setting

certificateSources - the certificate sources to

timeBasedContexts - the date comparison context for which to apply the setting

value - the settings value in milliseconds

Returns:

this same SignatureValidationProperties instance.

getContinueAfterFailure

public boolean getContinueAfterFailure(ValidationContext validationContext)

Returns the Continue after failure setting for the provided context or the default context.

Parameters:

validationContext - the context for which to retrieve the Continue after failure setting

Returns:

the Continue after failure setting for the provided context or the default context

setContinueAfterFailure

public final SignatureValidationProperties setContinueAfterFailure(ValidatorContexts validatorContexts,
                                                                   CertificateSources certificateSources,
                                                                   boolean value)

Sets the Continue after failure setting for the provided context.

This parameter specifies if validation is expected to continue after first failure is encountered. Only ValidationReport.ValidationResult.INVALID is considered to be a failure.

Parameters:

validatorContexts - the validators for which to set the Continue after failure setting

certificateSources - the certificateSources for which to set the Continue after failure setting

value - the Continue after failure setting

Returns:

this same SignatureValidationProperties instance.

getRevocationOnlineFetching

public SignatureValidationProperties.OnlineFetching getRevocationOnlineFetching(ValidationContext validationContext)

Sets the onlineFetching property representing possible online fetching permissions.

Parameters:

validationContext - the context for which to retrieve the online fetching setting

Returns:

the online fetching setting.

setRevocationOnlineFetching

public final SignatureValidationProperties setRevocationOnlineFetching(ValidatorContexts validatorContexts,
                                                                       CertificateSources certificateSources,

Returns:

this same SignatureValidationProperties instance.

getRequiredExtensions

public List<CertificateExtension> getRequiredExtensions(ValidationContext validationContext)

Returns required extension for the provided validation context.

Parameters:

validationContext - the validation context for which to retrieve required extensions

Returns:

required extensions for the provided validation context

setRequiredExtensions

public final SignatureValidationProperties setRequiredExtensions(CertificateSources certificateSources,

Adds list of extensions which are required to be set to a certificate depending on certificate source.

By default, required extensions are set to be compliant with common validation norms. Changing those can result in falsely positive validation result.

certificateSources - CertificateSource for extensions to be present

requiredExtensions - list of required CertificateExtension

Returns:

this same SignatureValidationProperties instance
