Class DAPBlock

java.lang.Object
  com.ibm.jc.DAPBlock

public class DAPBlock

extends java.lang.Object

Represents a DAP block as defined in Global Platform and as we save it in a CAP-file. In the latter case the X.509 public certificate is included if available.

                int len)
         throws JCException

Constructs a DAP block object based on the DAP information saved in a CAP file.

Parameters:

dapInfo - Info from the CAP file. The format is algorithm | DAP-block | [X.509 cert].

off - offset in dapInfo.

len - length of DAP information.

         throws JCException

Deprecated.

Constructs a DAP block.

Parameters:

aid - AID of the Security Domain to do the DAP verification.

sig - the DAP signature.

cert - optional RSA certificate used to generate the signature, might be null.
