use of org.openecard.common.apdu.common.CardCommandTemplate in project open-ecard by ecsec.

the class SignStep method performLegacySignature.

/**
 * The method performs the SignatureCreation if no standard commands are possible.
 * This method creates a signature with APDUs which are not covered by the methods defined in TR-03112 part 7.
 *
 * @param cryptoMarker A {@link CryptoMarkerType} object containing the information about the creation of a signature
 *   in a legacy way.
 * @param slotHandle A slotHandle identifying the current card.
 * @param templateCTX A Map containing the context data for the evaluation of the template variables. This object
 *   contains per default the message to sign and the {@link TLVFunction}.
 * @return A {@link SignResponse} object containing the signature of the <b>message</b>.
 * @throws APDUTemplateException Thrown if the evaluation of the {@link CardCommandTemplate} failed.
 * @throws APDUException Thrown if one of the commands to execute failed.
 * @throws WSHelper.WSException Thrown if the checkResult method of WSHelper failed.
