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>
    main()
  File "pkcs11-key-generation", line 115, in main
    kg = KeyGenerator()
  File "pkcs11-key-generation", line 38, in __init__
    ffi=ffi
  File "/root/barbican/barbican/plugin/crypto/pkcs11.py", line 315, in __init__
    self.lib = self.ffi.dlopen(library_path)
  File "/usr/lib64/python2.7/site-packages/cffi/api.py", line 127, in dlopen
    lib, function_cache = _make_ffi_library(self, name, flags)
  File "/usr/lib64/python2.7/site-packages/cffi/api.py", line 572, in _make_ffi_library
    backendlib = _load_backend_lib(backend, libname, flags)
  File "/usr/lib64/python2.7/site-packages/cffi/api.py", line 561, in _load_backend_lib
    return backend.load_library(name, flags)
OSError: cannot load library {/usr/lib/libCryptoki2_64.so}: {/usr/lib/libCryptoki2_64.so}: cannot open shared object file: No such file or directory

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
{"code": 500, "description": "Secret creation failure seen - please contact site administrator.", "title": "Internal Server Error"}[root at HSM-Client crypto]#

(I am not sure why we are geting CryptoPluginNotFound: Crypto plugin not found. Exception since the changes is able to hit the p11_crypto.py code)

2015-07-18 17:15:32.643 29838 ERROR barbican.api.controllers CryptoPluginNotFound: Crypto plugin not found.

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.
