Example 1 with UpdateBinary

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

the class TinySAL method dsiWrite.

/**
 * The DSIWrite function changes the content of a DSI (Data Structure for Interoperability).
 * See BSI-TR-03112-4, version 1.1.2, section 3.4.8.
 * For clarification this method updates an existing DSI and does not create a new one.
 *
 * The precondition for this method is that a connection to a card application was established and a data set was
 * selected. Furthermore the DSI exists already.
 *
 * @param request DSIWrite
 * @return DSIWriteResponse
