Random::Formatter#alphanumeric

SecureRandom.alphanumeric generates a random alphanumeric string.

The argument _n_ specifies the length, in characters, of the alphanumeric
string to be generated.

If _n_ is not specified or is nil, 16 is assumed.
It may be larger in the future.

The result may contain A-Z, a-z and 0-9.

  p SecureRandom.alphanumeric #=> "2BuBuLf3WfSKyQbR"
  p SecureRandom.alphanumeric(10) #=> "i6K93NdqiH"

If a secure random number generator is not available,
+NotImplementedError+ is raised.
