Hmm... This error is usually because one of the parameters is an incorrect type. I'm wondering if the length is coming through as a string instead of an integer. As the length defaults to 32, try not specifying the length parameter. If that works, we need to report a defect to make sure that it's properly converted to an integer.

Hi John ,
Thanks a lot John for your response.
I tried executing the script with the following options before , but it seems it did not work .Hence tried with the curly baraces .
Please find other options below :
[root at HSM-Client bin]# python pkcs11-key-generation --library-path '/usr/lib/libCryptoki2_64.so' --passphrase 'test123' --slot-id 1 mkek --length 32 --label 'an_mkek'
HSM returned response code: 0x13L CKR_ATTRIBUTE_VALUE_INVALID
[root at HSM-Client bin]# python pkcs11-key-generation --library-path /usr/lib/libCryptoki2_64.so --passphrase test123 --slot-id 1 mkek --length 32 --label an_mkek
HSM returned response code: 0x13L CKR_ATTRIBUTE_VALUE_INVALID
Would be of great help if l could the syntax for running the script
Thanks and Regards,
Asha Seshagiri

Don't include the curly brackets on the script arguments. The documentation is just using them to indicate that those are placeholders for real values.

Hi John ,
Thanks for pointing me to the right script.
I appreciate your help .
I tried running the script with the following command :
[root at HSM-Client bin]# python pkcs11-key-generation --library-path {/usr/lib/libCryptoki2_64.so} --passphrase {test123} --slot-id 1 mkek --length 32 --label 'an_mkek'
Traceback (most recent call last):
File "pkcs11-key-generation", line 120, in <module>

Unable to run the script since the library libCryptoki2_64.so cannot be opened.
Tried the following solution :
* vi /etc/ld.so.conf
* Added both the paths of ld.so.conf in the /etc/ld.so.conf file got from the command find / -name libCryptoki2_64.so
* /usr/safenet/lunaclient/lib/libCryptoki2_64.so
* /usr/lib/libCryptoki2_64.so
* sudo ldconfig
* ldconfig -p
But the above solution failed and am geting the same error.
Any help would highly be apprecited.
Thanks in advance!
Thanks and Regards,
Asha Seshagiri

Asha,
It looks like you don't have your mkek label correctly configured. Make sure that the mkek_label and hmac_label values in your config correctly reflect the keys that you've generated on your HSM.
The plugin will cache the key handle to the mkek and hmac when the plugin starts, so if it cannot find them, it'll fail to load the plugin altogether.
If you need help generating your mkek and hmac, refer to http://docs.openstack.org/developer/barbican/api/quickstart/pkcs11keygeneration.html for instructions on how to create them using a script.
As far as who uses HSMs, I know we (Rackspace) use them with Barbican.

Subject: [openstack-dev] Barbican : Unable to store the secret when Barbican was Integrated with SafeNet HSM
Hi All ,
I have configured Barbican to integrate with SafeNet HSM.
Installed safenet client libraries , registered the barbican machine to point to HSM server and also assigned HSM partition.
The following were the changes done in barbican.conf file
# ================= Secret Store Plugin ===================
[secretstore]
namespace = barbican.secretstore.plugin
enabled_secretstore_plugins = store_crypto
# ================= Crypto plugin ===================
[crypto]
namespace = barbican.crypto.plugin
enabled_crypto_plugins = p11_crypto
[p11_crypto_plugin]
# Path to vendor PKCS11 library
library_path = '/usr/lib/libCryptoki2_64.so'
# Password to login to PKCS11 session
login = 'test123'
# Label to identify master KEK in the HSM (must not be the same as HMAC label)
mkek_label = 'an_mkek'
# Length in bytes of master KEK
mkek_length = 32
# Label to identify HMAC key in the HSM (must not be the same as MKEK label)
hmac_label = 'my_hmac_label'
# HSM Slot id (Should correspond to a configured PKCS11 slot). Default: 1
slot_id = 1
Unable to store the secret when Barbican was integrated with HSM.
[root at HSM-Client crypto]# curl -X POST -H 'content-type:application/json' -H 'X-Project-Id:12345' -d '{"payload": "my-secret-here", "payload_content_type": "text/plain"}' http://localhost:9311/v1/secrets

Had chance to go though the code as to why are we geting the exception : P11CryptoKeyHandleException: No key handle was found .
It is because returned_count[0] == 0 .It needs to be 0 in order for the mkek to be created .From what I understand is that by default all the ffi variables would have the value 0 . I am not sure why the check returned_count[0] == 1: has been put .
if returned_count[0] == 1:
key = object_handle_ptr[0]
rv = self.lib.C_FindObjectsFinal(session)
self.check_error(rv)
if returned_count[0] == 1:
return key
elif returned_count[0] == 0:
return None
Need Help .Any help would highly be appreciated .It is very critical for us to integrate with Barbican
Also would like to know if any one has integrated Barbican with HSM.
