Method Detail

prepareBase64Content

public static String prepareBase64Content(SignatureData data)

Encodes the given SignatureData to a valid Base64Content.

The data is Base64 encoded. If the mime-type suggests that the data is binary, it is Base64 encoded for a second time.

Parameters:

data - The data to be converted to a valid Base64 content.

Returns:

Returns the Base64 content.

prepareEnvelopingData

public static byte[] prepareEnvelopingData(SignatureData data)

Prepares the enveloping data.

This is useful for building the hash.

Parameters:

data - The data to be prepared.

Returns:

Returns the prepared data.

checkResponseForError

public static void checkResponseForError(String response_string)
                                  throws ConnectorException

Checks the response xml for an error description and if found throws an appropriate exception.

Parameters:

response_string - The response xml.

Throws:

ConnectorException - f.e.

parseCreateXMLResponse

public static SignSignatureObject parseCreateXMLResponse(String xmlResponse,
                                                         IdFormatter id_formatter,
                                                         ConnectorEnvironment environment)
                                                  throws ConnectorException

This method parses the BKU-Response string.

It separates the SignatureValue, X509IssuerName, SigningTime, X509SerialNumber, X509Certificate, CertDigest, DigestValue and the signation id-s. If the X509Certificate is extracted it would be stored in the certificates directory.

Parameters:

xmlResponse - The response string.

Returns:

Returns the parsed signature object holding the data.

Throws:

ConnectorException - ErrorCode (303, 304)

SignatureObject, CodingHelper, X509Cert

removeAllWhitespace

public static String removeAllWhitespace(String str)

Removes all whitespaces ("\\s") from the String.

Parameters:

str - The String.

Returns:

The String with all whitespaces removed.

parseVerifyXMLResponse

public static SignatureResponse parseVerifyXMLResponse(String xmlResponse)

This method parses the verify response string and return a SignatureResponse object. The SignatureResponse object is filled out by the response values from the BKU-response.

Parameters:

xmlResponse - the response values from the BKU-verify request

Returns:

SignatureResponse object
