Subject: RE: [pkcs11] Key Import proposal update


Hi Doron -

Thanks! We'll review in our call today and see if we are ready to initiate a ballot accepting the proposal. 

Please upload the docs into the ''documents" folder in the PCKS 11 TC doc repository.

Regards,

Bob

Subject: [pkcs11] Key Import proposal update

I am attaching two documents with the new mechanisms proposal for the secure key import . 

The first is an updated description for key import using an RSA key . This copy only includes minor and typo  fixes - it updates the unwrapping description to indicate the use of CKM_AES_KEY_WRAP_PAD  (rather than CKM_AES_KEY_WRAP) . 

The second is a first cut of the ECC variant  .

Here is an update to the proposal  taking into account additional input from Mike .

Attached is the first draft of the proposed mechanism for secure key import using an RSA key.   
Assuming this is acceptable, I will provide the elliptic curve equivalent so both merged with the 2.4 new mechanisms document .
