# SecureRandom.base36 generates a random base36 string in lowercase.
#
# The argument _n_ specifies the length of the random string to be generated.
#
# If _n_ is not specified or is +nil+, 16 is assumed. It may be larger in the future.
# This method can be used over +base58+ if a deterministic case key is necessary.
#
# The result will contain alphanumeric characters in lowercase.
