Results for: "Array.new"

Comes from ripper, called on every parse error, msg is a string

Returns URL-unescaped string following RFC 3986.

Generates a private and public key unless a private key already exists. If this DH instance was generated from public DH parameters (e.g. by encoding the result of DH#public_key), then this method needs to be called first in order to generate the per-session keys before performing the actual key exchange.

Deprecated in version 3.0. This method is incompatible with OpenSSL 3.0.0 or later.

See also OpenSSL::PKey.generate_key.

Example:

# DEPRECATED USAGE: This will not work on OpenSSL 3.0 or later
dh0 = OpenSSL::PKey::DH.new(2048)
dh = dh0.public_key # #public_key only copies the DH parameters (contrary to the name)
dh.generate_key!
puts dh.private? # => true
puts dh0.pub_key == dh.pub_key #=> false

# With OpenSSL::PKey.generate_key
dh0 = OpenSSL::PKey::DH.new(2048)
dh = OpenSSL::PKey.generate_key(dh0)
puts dh0.pub_key == dh.pub_key #=> false

Validates the Diffie-Hellman parameters associated with this instance. It checks whether a safe prime and a suitable generator are used. If this is not the case, false is returned.

See also the man page EVP_PKEY_param_check(3).

Generates a new random private and public key.

See also the OpenSSL documentation for EC_KEY_generate_key()

Example

ec = OpenSSL::PKey::EC.new("prime256v1")
p ec.private_key # => nil
ec.generate_key!
p ec.private_key # => #<OpenSSL::BN XXXXXX>

Generates a new random private and public key.

See also the OpenSSL documentation for EC_KEY_generate_key()

Example

ec = OpenSSL::PKey::EC.new("prime256v1")
p ec.private_key # => nil
ec.generate_key!
p ec.private_key # => #<OpenSSL::BN XXXXXX>

Sets saner defaults optimized for the use with HTTP-like protocols.

If a Hash params is given, the parameters are overridden with it. The keys in params must be assignment methods on SSLContext.

If the verify_mode is not VERIFY_NONE and ca_file, ca_path and cert_store are not set then the system default certificate store is used.

Returns the successor integer of self (equivalent to self + 1):

1.succ  #=> 2
-1.succ #=> 0

Related: Integer#pred (predecessor value).

Returns self.

Returns the value as a rational. The optional argument eps is always ignored.

Return the class or module refined by the receiver.

module M
  refine String do
  end
end

M.refinements[0].target # => String

Returns a new Complex object formed from the arguments, each of which must be an instance of Numeric, or an instance of one of its subclasses: Complex, Float, Integer, Rational; see Rectangular Coordinates:

Complex.rect(3)             # => (3+0i)
Complex.rect(3, Math::PI)   # => (3+3.141592653589793i)
Complex.rect(-3, -Math::PI) # => (-3-3.141592653589793i)

Complex.rectangular is an alias for Complex.rect.

Returns a new Complex object formed from the arguments, each of which must be an instance of Numeric, or an instance of one of its subclasses: Complex, Float, Integer, Rational. Argument arg is given in radians; see Polar Coordinates:

Complex.polar(3)        # => (3+0i)
Complex.polar(3, 2.0)   # => (-1.2484405096414273+2.727892280477045i)
Complex.polar(-3, -2.0) # => (1.2484405096414273+2.727892280477045i)

Returns the imaginary value for self:

Complex(7).imaginary      #=> 0
Complex(9, -4).imaginary  #=> -4

If self was created with polar coordinates, the returned value is computed, and may be inexact:

Complex.polar(1, Math::PI/4).imag # => 0.7071067811865476 # Square root of 2.

Returns the argument (angle) for self in radians; see polar coordinates:

Complex.polar(3, Math::PI/2).arg  # => 1.57079632679489660

If self was created with rectangular coordinates, the returned value is computed, and may be inexact:

Complex.polar(1, 1.0/3).arg # => 0.33333333333333326

Returns the array [self.real, self.imag]:

Complex.rect(1, 2).rect # => [1, 2]

See Rectangular Coordinates.

If self was created with polar coordinates, the returned value is computed, and may be inexact:

Complex.polar(1.0, 1.0).rect # => [0.5403023058681398, 0.8414709848078965]

Complex#rectangular is an alias for Complex#rect.
