Creates an unsigned certificate for subject and key. The lifetime of the key is from the current time to age which defaults to one year.

The extensions restrict the key to the indicated uses.

Creates a new key pair of the specified length and algorithm. The default is a 3072 bit RSA key.

Enumerates the trusted certificates via Gem::Security::TrustDir.

Wraps text to wrap characters and optionally indents by indent characters

This code is based directly on the Text gem implementation Returns a value representing the “cost” of transforming str1 into str2

Terminates the RubyGems process with the given exit_code

Normalizes a request path. Raises an exception if the path cannot be normalized.

Normalizes a request path. Raises an exception if the path cannot be normalized.

Escapes path str

Creates TCP server sockets bound to address:port and returns them.

Processes the topmost available {RequirementState} on the stack @return [void]

@return [ResolutionState] the state whose ‘requirement` is the given

`requirement`.

Attempts to activate the current {#possibility} @return [void]

Generates a valid JSON document from object obj and returns the result. If no valid JSON document can be created this method raises a GeneratorError exception.

Returns the generator of the group.

See the OpenSSL documentation for EC_GROUP_get0_generator()

Tags the current state of the dependency as the given tag @param [Object] tag an opaque tag for the current state of the graph @return [Void]

Returns the value of the given instance variable, or nil if the instance variable is not set. The @ part of the variable name should be included for regular instance variables. Throws a NameError exception if the supplied symbol is not valid as an instance variable name. String arguments are converted to symbols.

class Fred
  def initialize(p1, p2)
    @a, @b = p1, p2
  end
end
fred = Fred.new('cat', 99)
fred.instance_variable_get(:@a)    #=> "cat"
fred.instance_variable_get("@b")   #=> 99

Sets the instance variable named by symbol to the given object, thereby frustrating the efforts of the class’s author to attempt to provide proper encapsulation. The variable does not have to exist prior to this call. If the instance variable name is passed as a string, that string is converted to a symbol.

class Fred
  def initialize(p1, p2)
    @a, @b = p1, p2
  end
end
fred = Fred.new('cat', 99)
fred.instance_variable_set(:@a, 'dog')   #=> "dog"
fred.instance_variable_set(:@c, 'cat')   #=> "cat"
fred.inspect                             #=> "#<Fred:0x401b3da8 @a=\"dog\", @b=99, @c=\"cat\">"

Returns true if the given instance variable is defined in obj. String arguments are converted to symbols.

class Fred
  def initialize(p1, p2)
    @a, @b = p1, p2
  end
end
fred = Fred.new('cat', 99)
fred.instance_variable_defined?(:@a)    #=> true
fred.instance_variable_defined?("@b")   #=> true
fred.instance_variable_defined?("@c")   #=> false

Removes the named instance variable from obj, returning that variable’s value. String arguments are converted to symbols.

class Dummy
  attr_reader :var
  def initialize
    @var = 99
  end
  def remove
    remove_instance_variable(:@var)
  end
end
d = Dummy.new
d.var      #=> 99
d.remove   #=> 99
d.var      #=> nil
