Constructor Detail

TPMPubKeyWrapper

public TPMPubKeyWrapper(java.nio.ByteBuffer bb,
                        boolean pcr_present)

Parse a public key from a TPM structure

Parameters:

bb -

pcr_present - whether a PCRInfo field is present in the key

TPMPubKeyWrapper

public TPMPubKeyWrapper(byte[] raw,
                        boolean pcr_present)

Parse a public key from a TPM structure

Parameters:

raw -

pcr_present - whether a PCRInfo field is present in the key

TPMPubKeyWrapper

public TPMPubKeyWrapper()

TPMPubKeyWrapper

public TPMPubKeyWrapper(java.security.PublicKey pk)

Wrap an existing RSA-PublicKey into a TPMPubKey Structure. Note that not all fields are filled, this is mainly a convenience function for Privacy CAs

Parameters:

pk -

Method Detail

buildBuffer

public byte[] buildBuffer(boolean pcr_present)

Create a native TPM structure using the information given in this field

Parameters:

pcr_present - whether a PCRInfo field should be present in the assembled structure

Returns:

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getRSAPubKey

public java.security.PublicKey getRSAPubKey()
