Thanks for the help, im going to try to extract this information from
the key stored in the MPIs.
Is there a way to import an RSA key from external source that is not
DER encoded nor KEA?
otherwise im gonna have to build a custom PK11_MakeRSAPubKey to create
a SECKEYPublicKey from raw bytes, filling the
modulusItem.data = modulusData;
modulusItem.len = modulusLen;
exponentItem.data = exponentData;
exponentItem.len = exponentLen;
with the info from the raw bytes.
thanks again!
