Issues with RSA public key

[christopherL91]

Hi,

Thank yoy soo much for your time spent on this project, looking forward exploring it some more.

I had a quick question regarding the use of this library and it's something I've been struggeling with for a while now.

        let rsa_pub = RsaPublicKey::from_public_key_pem(&response.pem)
            .map_err(|e| format!("RSA PEM parse error: {:?}", e))
            .unwrap();

        let pkcs1_der_document = rsa_pub
            .to_pkcs1_der()
            .map_err(|e| anyhow::anyhow!("PKCS#1 DER encode error: {}", e))?;

        let result = KSMPublicKey {
            id: Sha256::digest(response.name.as_bytes()).to_vec(),
            label: response.name,
            algorithm: KeyAlgorithm::Rsa,
            der: pkcs1_der_document.into_vec(),
        };

Is this correct?

Getting weird error message when using pkcs11-tool

warning: PKCS11 function C_GetAttributeValue(MODULUS_BITS) failed: rv = CKR_ATTRIBUTE_TYPE_INVALID (0x12)
warning: PKCS11 function C_GetAttributeValue(ENCRYPT) failed: rv = CKR_ATTRIBUTE_TYPE_INVALID (0x12)
warning: PKCS11 function C_GetAttributeValue(VERIFY) failed: rv = CKR_ATTRIBUTE_TYPE_INVALID (0x12)
warning: PKCS11 function C_GetAttributeValue(VERIFY_RECOVER) failed: rv = CKR_ATTRIBUTE_TYPE_INVALID (0x12)
warning: PKCS11 function C_GetAttributeValue(WRAP) failed: rv = CKR_ATTRIBUTE_TYPE_INVALID (0x12)

Based on the info I can see in the attributes.rs file these values should be injected automatically but maybe I'm missing something?

Should I also implement any more C_* functions other than C_GetFunctionList ?

Currently building a GCP KMS module that is mostly working but there are still some weird edge cases I need to solve.

Thank you

Using library versions:

native-pkcs11 = "0.2.27"
native-pkcs11-traits = "0.2.27"

Are you able to post a small reproduction repository by chance?
