According to https://lapo.it/asn1js/ your private key in PEM encoding is still an encrypted one - directly visible with "-----BEGIN ENCRYPTED PRIVATE KEY-----":

QUESTION

Hot to use mechanisms CKM_ECDH1_DERIVE with pkcs11interop

Asked 2017-Jun-29 at 19:42

I bought a NitroKey HSM and wanted to derive a secret with EC. Previosly question

For this, I want to use the CKM_ECDH1_DERIVE mechanisms. Which is supported by this HSM, see:

Referring to the PKCS#11 specification this must be considered:

The mechanism CKM_ECDH1_DERIVE must be used with the function Derive (Page 188)
The mechanism CKM_ECDH1_DERIVE expects parameter CK_ECDH1_DERIVE_PARAMS (Page 222) with this arguments:
1. kdf: Key derivation function used on the shared secret value (CKD)
2. sharedData: Some data shared between the two parties
3. publicData: Other party's EC public key value
The function DeriveKey expects these arguments:
1. Mechanism CKM.CKM_ECDH1_DERIVE
2. ObjectHandle PrivateKey
3. ObjectAttributes (Page 338)
  1. CKA.CKA_CLASS -> CKO.CKO_SECRET_KEY
  2. CKA.CKA_KEY_TYPE -> CKK.CKK_GENERIC_SECRET
  3. But "However, since these facts are all implicit in the mechanism, there is no need to specify any of them" so these can be null?

Problem

So with this information, I tried to implement a method.

But I get this Error:

Net.Pkcs11Interop.Common.Pkcs11Exception : Method C_DeriveKey returned CKR_TEMPLATE_INCOMPLETE

at Session.DeriveKey.

Explanation of CKR_TEMPLATE_INCOMPLETE (Page 64):

If the attribute values in the supplied template, together with any default attribute values and any attribute values contributed to the object by the object-creation function itself, are insufficient to fully specify the object to create, then the attempt should fail with the error code CKR_TEMPLATE_INCOMPLETE.

and here (Page 98)

CKR_TEMPLATE_INCOMPLETE: The template specified for creating an object is incomplete, and lacks some necessary attributes. See Section 10.1 for more information.

But I used the nesseary attributes:

CKA.CKA_CLASS -> CKO.CKO_SECRET_KEY
CKA.CKA_KEY_TYPE -> CKK.CKK_GENERIC_SECRET

Ideas?

Code ...

That's a very nice and complete description of a problem.

CKR_TEMPLATE_INCOMPLETE is always very painful to deal with because almost every library vendor expect different set of attributes to be provided and this error does not reveal which exact attributes are missing.

After a quick look at OpenSC source code I would try with following template:
