getPcrValue

public TcBlobData getPcrValue(long pcrIndex)
                       throws TcTssException

Description copied from interface: TcIPcrComposite

This method returns the digest value of a given PCR index inside a PCR composite object. Multiple PCR values for different indices can be retrieved by calling this method multiple times on a PCR composite object.
This method may be used to get PCR values in a PCR composite object regardless of the PCR structure type (TcTpmPcrInfo, TcTpmPcrInfoShort or TcTpmPcrInfoLong).
If a TcTpmPcrInfoLong is used, this method returns the digestAtRelease.

Specified by:

getPcrValue in interface TcIPcrComposite

Parameters:

pcrIndex - The index of the PCR to read.

Returns:

The contents of PCR specified by pcrIndex.

Throws:

TcTssException

setAttribPcrStruct

public void setAttribPcrStruct(long subFlag,
                               long attrib)
                        throws TcTssException

This method is used to set PCR composite attributes. The only attribute defined in the TSS specification is the PCR composite structure attribute. Since it makes little sense to change the underlying structure after the PCR composite object was created, this attribute is not supported. To specify the underlying struct version, use the init flags upon object creation. Note that this method is not standardized as part of the TSP Interface (TSPI).

Throws:

{@link - TcTssException}

TcTssException

getAttribPcrStruct

public long getAttribPcrStruct(long subFlag)
                        throws TcTssException

This method is used to get PCR composite attributes. Note that this method is not standardized as part of the TSP Interface (TSPI).

Parameters:

subFlag - Valid subFlags are:

• TcTssConstants.TSS_TSPATTRIB_PCRSINFO_PCRSTRUCT

Returns:

The type of internal PCR data structure. This can be of type TcTssConstants.TSS_PCRS_STRUCT_INFO, TcTssConstants.TSS_PCRS_STRUCT_INFO_SHORT or TcTssConstants.TSS_PCRS_STRUCT_INFO_LONG.

Throws:

{@link - TcTssException}

TcTssException
