[Trustedjava-support] APKI and openssl

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

Dear all,

I am trying to process the EK Certificate created through the APKI PCA 
implementation through openssl.

The creation of the certificate works fine and i am able to output the 
pubic key through the java code.

When I execute the following openssl command i get an error:
openssl -inform PEM -in cert.pem -noout -modulus

The error is:
Modulus=unavailable
4716:error:0D09B0A3:asn1 encoding routines:d2i_PublicKey:unknown public 
key type:d2i_pu.c:125:
4716:error:0B077066:x509 certificate routines:X509_PUBKEY_get:err asn1 
lib:x_pubkey.c:366:

The JAVA code which stores the certificate in the file is:
FileOutputStream fo = new FileOutputStream(filename);
fo.write(iaik.utils.Util.toPemString(cert).getBytes());
fo.close();

It looks like the public key isn't encoded in the right manner.

Has anyone a suggestion?
Thank you in advance!

Kind regards,
Simon Mittelberger
