object --+
         |
        BasicConstraints

An object representing X509 Basic Constraints Extension
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, ...)
 
__str__(x)
str(x)
string)
format(level=0, indent=' ')
This is equivalent to: indented_format(obj.format_lines()) on an object providing a format_lines() method.
[(level, string),...]
format_lines(level=0)
Formats the object into a sequence of lines with indent level information.
Properties [hide private]
  is_ca
returns boolean, True if certificate is a certificate authority (i.e.
  path_len
returns max path length constraint as an integer

__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__

__str__(x)
(Informal representation operator)

 
str(x)
Overrides: object.__str__

format(level=0, indent=' ')

 
This is equivalent to: indented_format(obj.format_lines()) on an object providing a format_lines() method.
Parameters:
  • level (integer) - Initial indentation level, all subsequent indents are relative to this starting level.
  • indent (string) - string replicated once for each indent level then prepended to output line
Returns: string)

format_lines(level=0)

 

Formats the object into a sequence of lines with indent level information. The return value is a list where each list item is a tuple. The first item in the tuple is an integer representing the indentation level for that line. Any remaining items in the tuple are strings to be output on that line.

The output of this function can be formatted into a single string by calling nss.nss.indented\_format(), e.g.:

print indented_format(obj.format_lines())

The reason this function returns a tuple as opposed to an single indented string is to support other text formatting systems such as GUI's with indentation controls. See nss.nss.indented\_format() for a complete explanation.

Parameters:
  • level (integer) - Initial indentation level, all subsequent indents are relative to this starting level.
Returns: [(level, string),...]

is_ca

returns boolean, True if certificate is a certificate authority (i.e. CA)
