pycontrol 2 and key_generate

Ok, this should get you working. Notice a few things - if a kwarg is singular, it's not a list. So 'mode' here doesn't expect to be a list. Also, for simply 'Sequence' types like these, you don't have to create that type explicitly. Just wrap it in a list bracket and you're off and rolling. Anyhow, here's the way to generate this, with some notes added.

In [58]: km.key_generate.params  Let's check out the params we expect to pass in. Notice that the "mode" param isn't a sequence, so it's not a list...
Out[58]:
[(mode, u'Management.KeyCertificate.ManagementModeType'),
 (keys, u'Management.KeyCertificate.KeySequence'),
 (x509_data, u'Management.KeyCertificate.X509DataSequence'),
 (create_optional_cert_csr, u'boolean'),
 (overwrite, u'boolean')]
 Cool, now let's start creating some objects to pass into the keys, x509_data kwargs.
In [62]: key = km.typefactory.create('Management.KeyCertificate.Key')  NOTE: I didn't create the sequence. If you do a dir() on this key object, you'll see all of the attributes listed in the SDK. Let's set them now.
In [63]: key.id = 'tetkey.domain.com'
In [65]: key.key_type = 'KTYPE_RSA_PRIVATE'
In [66]: key.bit_length = 1024
In [67]: key.security = 'STYPE_NORMAL'

 Same routine exactly for the x509 stuff. Notice I didn't create the 'Sequence' object here either...The actual XML data is marshalled into the object below as attributes.
In [68]: x509data = km.typefactory.create('Management.KeyCertificate.X509Data')
In [69]: x509data.common_name = 'testkey.deloitte.com'
In [70]: x509data.country_name = 'US'
In [71]: x509data.state_name = 'New York'
In [72]: x509data.locality_name = 'New York'
In [73]: x509data.organization_name = 'Company'
In [75]: x509data.division_name = 'Team'

 Let's see what happens with the generation now!
In [76]:  km.key_generate(mode = 'MANAGEMENT_MODE_DEFAULT',keys = [key],x509_data = [x509data],create_optional_cert_csr = True,overwrite = False)

 Let's confirm:
In [79]: km.get_certificate_request_list(mode = 'MANAGEMENT_MODE_DEFAULT')
Out[79]:[(Management.KeyCertificate.CertificateRequestInformation){
   csr_info =
      (Management.KeyCertificate.CertificateRequest){
         id = "default"
         email = None
         challenge_password = None
      }
   title = None
   serial_number = None
   file_name = "/config/ssl/ssl.csr/default.csr"
   key_type = "KTYPE_RSA_PUBLIC"
   bit_length = 1024
   subject =
      (Management.KeyCertificate.X509Data){
         common_name = "localhost.localdomain"
         country_name = "US"
         state_name = "WA"
         locality_name = "Seattle"
         organization_name = "MyCompany"
         division_name = "IT"
      }
 },
 (Management.KeyCertificate.CertificateRequestInformation){
   csr_info =
      (Management.KeyCertificate.CertificateRequest){
         id = "tetkey.domain.com"
         email = None
         challenge_password = None
      }
   title = None
   serial_number = None
   file_name = "/config/ssl/ssl.csr/tetkey.domain.com.csr"
   key_type = "KTYPE_RSA_PUBLIC"
   bit_length = 1024
   subject =
      (Management.KeyCertificate.X509Data){
         common_name = "testkey.deloitte.com"
         country_name = "US"
         state_name = "New York"
         locality_name = "New York"
         organization_name = "Company"
         division_name = "Team"
      }
 }]
 Ding!

Hope this helps. Please post back any questions you've got as it relates to the types. Also, if you've not had a look at the pycontrol tutorial videos it may be worth looking; I go into a little bit of how the types work, as well as the SDK's semantics.
