Re: [Trustedjava-support] Load SRK encrypted key pair from disc

[Ronald T. <ron...@ia...>]

Hi Gianfranco,

With jTSS you can load keys from a byte array, which contains a TCG 
specified TPM_KEY repectively a TPM_KEY12 structure. In the 
loadKeyByBlob method you can also specify the SRK as parent.

However, I do not have the faintest idea how libengine-tpm-openssl keys 
are formatted and therefore I cannot tell you the details of how to 
import them to jTSS.

hth, Ronald
