[Trustedjava-support] Creating EKCertificate

[Simon M. <sim...@in...>]

Hello,

i am currently trying to create an EKCertificate, but i get this exception:

Exception in thread "main" java.lang.RuntimeException: BUG? cannot 
convert key to OAEP
    at iaik.tc.cert.common.Common.publicRSAtoPublicRSAOAEP(Common.java:352)
    at iaik.tc.cert.EKCertificate.create(EKCertificate.java:150)
    ....

The code which generates this is the following:

X509Certificate ekCertificate = EKCertificate.create(prop, 
privacyCACertificate, privKeyPrivacyCa_, ekPubKey);

If i create the ekPubKey by myself, using KeyPairGenerator it all works 
fine.
But when i want to use the PublicEK from the TPM it fails with the above 
described error message.

I get the EK from the TPM with the following Code:

TcTpmPubkey pubTPMEK = new 
TcTpmPubkey(tpm.getPubEndorsementKeyOwner().getPubKey());
RSAPublicKey ekPubKey =  TcCrypto.pubTpmKeyToJava(pubTPMEK);

I hope for some advice.

Thank you,
best regards
