Instance Methods [hide private]
 
__init__(...)
x.__init__(...) initializes x; see help(type(x)) for signature
a new object with type S, a subtype of T
__new__(T, S, ...)
length
get_best_key_length(mechanism)
Return the best key length for this slot and mechanism.
mechanism
get_best_wrap_mechanism()
Find the best key wrap mechanism for this slot.
bool
is_hw()
Finds out whether a slot is implemented in hardware or software.
bool
is_present()
Finds out whether the token for a slot is available.
bool
is_read_only()
Finds out whether a slot is read-only.

Method Details [hide private]

__init__(...)
(Constructor)

 
x.__init__(...) initializes x; see help(type(x)) for signature
Overrides: object.__init__

__new__(T, S, ...)

 
Returns: a new object with type S, a subtype of T
Overrides: object.__new__

get_best_key_length(mechanism)

 
Return the best key length for this slot and mechanism. A zero result means that token knows how long the key should be, the result is typically used with key_gen(), token_key_gen(), or token_key_gen_with_flags()
Parameters:
  • mechanism (int) - key mechanism enumeration constant (CKM_*)
Returns: length

key_gen(...)

 

key_gen(mechanism, sec_param, key_size, [user_data1, ...]) -> PK11SymKey object

Generate a symmetric key.

Parameters:
  • mechanism (int) - key mechanism enumeration constant (CKM_*)
  • key_param (SecItem object or None) - SecItem key parameters. None is also valid.
  • key_size (int) - key length (use get_best_key_length())
  • user_dataN (object ...) - zero or more caller supplied parameters which will be passed to the password callback function
