Creates a self-signed certificate with an issuer and subject from email, a subject alternative name of email and the given extensions for the key.
Returns the result of the peer certificates verification. See verify(1) for error values and descriptions.
If no peer certificate was presented X509_V_OK is returned.
Convert klassname to a Class
Extracts the certificate chain from the spec and calls verify to ensure the signatures and certificate chain is valid according to the policy..
@return [Array<Array<Object>>] The different requirement
trees that led to every requirement for the current spec.
Returns a new Array containing only those elements from self that are not found in any of the Arrays other_arrays; items are compared using eql?; order from self is preserved:
[0, 1, 1, 2, 1, 1, 3, 1, 1].difference([1]) # => [0, 2, 3] [0, 1, 2, 3].difference([3, 0], [1, 3]) # => [2] [0, 1, 2].difference([4]) # => [0, 1, 2]
Returns a copy of self if no arguments given.
Related: Array#-.
Returns true if the count of elements in self is zero, false otherwise.
Returns a new Array whose elements are all those from self for which the block returns false or nil:
a = [:foo, 'bar', 2, 'bat'] a1 = a.reject {|element| element.to_s.start_with?('b') } a1 # => [:foo, 2]
Returns a new Enumerator if no block given:
a = [:foo, 'bar', 2] a.reject # => #<Enumerator: [:foo, "bar", 2]:reject>
Removes each element for which the block returns a truthy value.
Returns self if any elements removed:
a = [:foo, 'bar', 2, 'bat'] a.reject! {|element| element.to_s.start_with?('b') } # => [:foo, 2]
Returns nil if no elements removed.
Returns a new Enumerator if no block given:
a = [:foo, 'bar', 2] a.reject! # => #<Enumerator: [:foo, "bar", 2]:reject!>
Replaces the content of self with the content of other_array; returns self:
a = [:foo, 'bar', 2] a.replace(['foo', :bar, 3]) # => ["foo", :bar, 3]
Prepends the given objects to self:
a = [:foo, 'bar', 2] a.unshift(:bam, :bat) # => [:bam, :bat, :foo, "bar", 2]
Array#prepend is an alias for Array#unshift.
Calculates the set of unambiguous abbreviations for the strings in self.
require 'abbrev' %w{ car cone }.abbrev #=> {"car"=>"car", "ca"=>"car", "cone"=>"cone", "con"=>"cone", "co"=>"cone"}
The optional pattern parameter is a pattern or a string. Only input strings that match the pattern or start with the string are included in the output hash.
%w{ fast boat day }.abbrev(/^.a/) #=> {"fast"=>"fast", "fas"=>"fast", "fa"=>"fast", "day"=>"day", "da"=>"day"} Abbrev.abbrev(%w{car box cone}, "ca") #=> {"car"=>"car", "ca"=>"car"}

Prevents further modifications to obj. A FrozenError will be raised if modification is attempted. There is no way to unfreeze a frozen object. See also Object#frozen?.
This method returns self.
a = [ "a", "b", "c" ] a.freeze a << "z"
produces:
prog.rb:3:in `<<': can't modify frozen Array (FrozenError) from prog.rb:3
Objects of the following classes are always frozen: Integer, Float, Symbol.
Returns the predecessor of self (equivalent to self - 1):
1.pred #=> 0 -1.pred #=> -2
Related: Integer#succ (successor value).
Returns self modulo other as a real number.
For integer n and real number r, these expressions are equivalent:
n % r n-r*(n/r).floor n.divmod(r)[1]
See Numeric#divmod.
Examples:
10 % 2 # => 0 10 % 3 # => 1 10 % 4 # => 2 10 % -2 # => 0 10 % -3 # => -2 10 % -4 # => -2 10 % 3.0 # => 1.0 10 % Rational(3, 1) # => (1/1)
Integer#modulo is an alias for Integer#%.
Returns a 2-element array [q, r], where
q = (self/other).floor # Quotient r = self % other # Remainder
Examples:
11.divmod(4) # => [2, 3] 11.divmod(-4) # => [-3, -1] -11.divmod(4) # => [-3, 1] -11.divmod(-4) # => [2, -3] 12.divmod(4) # => [3, 0] 12.divmod(-4) # => [-3, 0] -12.divmod(4) # => [-3, 0] -12.divmod(-4) # => [3, 0] 13.divmod(4.0) # => [3, 1.0] 13.divmod(Rational(4, 1)) # => [3, (1/1)]
Returns true if int is an even number.
Returns a complex object which denotes the given rectangular form.
Complex.rectangular(1, 2) #=> (1+2i)
Returns a complex object which denotes the given rectangular form.
Complex.rectangular(1, 2) #=> (1+2i)
