All Implemented Interfaces:

Closeable, AutoCloseable
```
public class Tpm
extends TpmBase
```
The Tpm class provides Java functions to program a TPM.
TPM-defined functions have names like TPM2_PCR_Read(): the TPM2_ prefix is dropped in the Java definition of these functions: e.g. PCR_Read().
The Tpm and TpmBase classes also provide a few helper-functions: for example, the command _allowErrors() tells Tpm to not throw an exception if the Next TPM command returns an error.
Tpm objects must be "connected" to a physical TPM or simulator using the _setDevice() method. Some devices (like the TPM simulator) need to be configured before they can be used. See the sample code that is part of the TSS.Java distribution for more information.

  - Startup
```
public void Startup(TPM_SU startupType)
```
    TPM2_Startup() is always preceded by _TPM_Init, which is the physical indication that TPM initialization is necessary because of a system-wide reset. TPM2_Startup() is only valid after _TPM_Init. Additional TPM2_Startup() commands are not allowed after it has completed successfully. If a TPM requires TPM2_Startup() and another command is received, or if the TPM receives TPM2_Startup() when it is not required, the TPM shall return TPM_RC_INITIALIZE.
    
    Parameters:
    
    startupType - TPM_SU_CLEAR or TPM_SU_STATE
  - Shutdown
```
public void Shutdown(TPM_SU shutdownType)

                                                 TPM_ALG_ID authHash)
```
    This command is used to start an authorization session using alternative methods of establishing the session key (sessionKey). The session key is then used to derive values used for authorization and for encrypting parameters.
    
    Parameters:
    
    tpmKey - handle of a loaded decrypt key used to encrypt salt may be TPM_RH_NULL Auth Index: None
    
    bind - entity providing the authValue may be TPM_RH_NULL Auth Index: None
    
    nonceCaller - initial nonceCaller, sets nonceTPM size for the session shall be at least 16 octets
    
    encryptedSalt - value encrypted according to the type of tpmKey If tpmKey is TPM_RH_NULL, this shall be the Empty Buffer.
    
    sessionType - indicates the type of the session; simple HMAC or policy (including a trial policy)
    
    symmetric - the algorithm and key size for parameter encryption may select TPM_ALG_NULL
    
    authHash - hash algorithm to use for the session Shall be a hash algorithm supported by the TPM and not TPM_ALG_NULL
    
    Returns:
    
    TPM2_StartAuthSession_RESPONSE{(ul)(li)(code)handle(/code) - handle for the newly created session(/li)(li)(code)nonceTPM(/code) - the initial nonce from the TPM, used in the computation of the sessionKey(/li)(/ul)}
  - PolicyRestart
```
public void PolicyRestart(TPM_HANDLE sessionHandle)
```
    This command allows a policy authorization session to be returned to its initial state. This command is used after the TPM returns TPM_RC_PCR_CHANGED. That response code indicates that a policy will fail because the PCR have changed after TPM2_PolicyPCR() was executed. Restarting the session allows the authorizations to be replayed because the session restarts with the same nonceTPM. If the PCR are valid for the policy, the policy may then succeed.
    
    Parameters:
    
    sessionHandle - the handle for the policy session
  - Create
```
public CreateResponse Create(TPM_HANDLE parentHandle,
                             TPMS_SENSITIVE_CREATE inSensitive,

                             TPMS_PCR_SELECTION[] creationPCR)
```
    This command is used to create an object that can be loaded into a TPM using TPM2_Load(). If the command completes successfully, the TPM will create the new object and return the objects creation data (creationData), its public area (outPublic), and its encrypted sensitive area (outPrivate). Preservation of the returned data is the responsibility of the caller. The object will need to be loaded (TPM2_Load()) before it may be used. The only difference between the inPublic TPMT_PUBLIC template and the outPublic TPMT_PUBLIC object is in the unique field.
    
    Parameters:
    
    parentHandle - handle of parent for new object Auth Index: 1 Auth Role: USER
    
    inSensitive - the sensitive data
    
    inPublic - the public template
    
    outsideInfo - data that will be included in the creation data for this object to provide permanent, verifiable linkage between this object and some object owner data

  - PolicyTicket
```
public void PolicyTicket(TPM_HANDLE policySession,
                         byte[] timeout,
                         byte[] cpHashA,
                         byte[] policyRef,
                         byte[] authName,
                         TPMT_TK_AUTH ticket)
```
    This command is similar to TPM2_PolicySigned() except that it takes a ticket instead of a signed authorization. The ticket represents a validated authorization that had an expiration time associated with it.
    
    Parameters:
    
    policySession - handle for the policy session being extended Auth Index: None
    
    timeout - time when authorization will expire The contents are TPM specific. This shall be the value returned when ticket was produced.
    
    cpHashA - digest of the command parameters to which this authorization is limited If it is not limited, the parameter will be the Empty Buffer.
    
    policyRef - reference to a qualifier for the policy may be the Empty Buffer
    
    authName - name of the object that provided the authorization
    
    ticket - an authorization ticket returned by the TPM in response to a TPM2_PolicySigned() or TPM2_PolicySecret()
  - PolicyOR
```
public void PolicyOR(TPM_HANDLE policySession,
                     TPM2B_DIGEST[] pHashList)
```
    This command allows options in authorizations without requiring that the TPM evaluate all of the options. If a policy may be satisfied by different sets of conditions, the TPM need only evaluate one set that satisfies the policy. This command will indicate that one of the required sets of conditions has been satisfied.
    
    Parameters:
    
    policySession - handle for the policy session being extended Auth Index: None
    
    pHashList - the list of hashes to check for a match
  - PolicyPCR
```
public void PolicyPCR(TPM_HANDLE policySession,
                      byte[] pcrDigest,
                      TPMS_PCR_SELECTION[] pcrs)
```
    This command is used to cause conditional gating of a policy based on PCR. This command together with TPM2_PolicyOR() allows one group of authorizations to occur when PCR are in one state and a different set of authorizations when the PCR are in a different state.
    
    Parameters:
    
    policySession - handle for the policy session being extended Auth Index: None
    
    pcrDigest - expected digest value of the selected PCR using the hash algorithm of the session; may be zero length
    
    pcrs - the PCR to include in the check digest
  - PolicyLocality
```
public void PolicyLocality(TPM_HANDLE policySession,
                           TPMA_LOCALITY locality)

                     byte[] operandB,
                     int offset,
                     TPM_EO operation)
```
    This command is used to cause conditional gating of a policy based on the contents of an NV Index. It is an immediate assertion. The NV index is validated during the TPM2_PolicyNV() command, not when the session is used for authorization.
    
    Parameters:
    
    authHandle - handle indicating the source of the authorization value Auth Index: 1 Auth Role: USER
    
    nvIndex - the NV Index of the area to read Auth Index: None

```
public void PolicyCommandCode(TPM_HANDLE policySession,
                              TPM_CC code)
```
    This command indicates that the authorization will be limited to a specific command code.
    
    Parameters:
    
    policySession - handle for the policy session being extended Auth Index: None
    
    code - the allowed commandCode

```
public void PolicyNameHash(TPM_HANDLE policySession,
                           byte[] nameHash)
```
    This command allows a policy to be bound to a specific set of TPM entities without being bound to the parameters of the command. This is most useful for commands such as TPM2_Duplicate() and for TPM2_PCR_Event() when the referenced PCR requires a policy.
    
    Parameters:
    
    policySession - handle for the policy session being extended Auth Index: None
    
    nameHash - the digest to be added to the policy
  - PolicyDuplicationSelect

                            TPMT_TK_VERIFIED checkTicket)
```
    This command allows policies to change. If a policy were static, then it would be difficult to add users to a policy. This command lets a policy authority sign a new policy so that it may be used in an existing policy.
    
    Parameters:
    
    policySession - handle for the policy session being extended Auth Index: None

public void PolicyNvWritten(TPM_HANDLE policySession,
                            byte writtenSet)
```
    This command allows a policy to be bound to the TPMA_NV_WRITTEN attributes. This is a deferred assertion. Values are stored in the policy session context and checked when the policy is used for authorization.
    
    Parameters:
    
    policySession - handle for the policy session being extended Auth Index: None
    
    writtenSet - YES if NV Index is required to have been written NO if NV Index is required not to have been written

                              TPM_HANDLE policySession)
```
    This command provides a capability that is the equivalent of a revocable policy. With TPM2_PolicyAuthorize(), the authorization ticket never expires, so the authorization may not be withdrawn. With this command, the approved policy is kept in an NV Index location so that the policy may be changed as needed to render the old policy unusable.
    
    Parameters:
    
    authHandle - handle indicating the source of the authorization value Auth Index: 1 Auth Role: USER
    
    nvIndex - the NV Index of the area to read Auth Index: None
    
    policySession - handle for the policy session being extended Auth Index: None

```
    This command is used to create a Primary Object under one of the Primary Seeds or a Temporary Object under TPM_RH_NULL. The command uses a TPM2B_PUBLIC as a template for the object to be created. The size of the unique field shall not be checked for consistency with the other object parameters. The command will create and load a Primary Object. The sensitive area is not returned.
    
    Parameters:
    
    primaryHandle - TPM_RH_ENDORSEMENT, TPM_RH_OWNER, TPM_RH_PLATFORM+{PP}, or TPM_RH_NULL Auth Index: 1 Auth Role: USER
