Constructor Details

CertificateExtension

             public CertificateExtension
             (String extensionOid, IASN1Primitive extensionValue)
            

Create new instance of CertificateExtension using provided extension OID and value.

Parameters:

extensionOid - String, which represents extension OID

extensionValue - IASN1Primitive, which represents extension value

Method Details

getExtensionValue

             public IASN1Primitive getExtensionValue()
            

Get extension value

Returns:

IASN1Primitive, which represents extension value

getExtensionOid

             public String getExtensionOid()
            

Get extension OID

Returns:

String, which represents extension OID

getMessage

             public String getMessage()
            

Returns a message with extra information about the check.

Returns:

a message with extra information about the check.

existsInCertificate

             public boolean existsInCertificate
             (X509Certificate certificate)
            

Check if this extension is present in the provided certificate.

This method doesn't always require complete extension value equality, instead whenever possible it checks that this extension is present in the certificate.

Parameters:

certificate - X509Certificate in which this extension shall be present

Returns:

true if extension if present, false otherwise
