cipher Integer to another Integer, make customer confused with the real number
Add this line to your application's Gemfile:
gem 'id_cipher'
And then execute:
$ bundle
Or install it yourself as:
$ gem install id_cipher
set cipher slat in two ways:
-
if use this in ruby on rails, add config in
settings.yml:Settings.id_cipher_key = 'something.like.this' -
or set IdCipher::KEY direct
module IdCipher KEY = 'something.like.this' end
notice: the key length must be over 16, should not longer than 256.
IdCipher.encrypt(1) # puts 42491238512
IdCipher.decrypt(42491238512) # puts 1
the result about encrypt is depend on key
IdCipher has two method, most of time, result of two method will be same. but DO NOT use them obscurely.
ID cipher use C pack function, so it has up limmit for id,
pack function use 'L' type pack id, it's a unsigned long type,
value range is 0~(2**32 - 1), means it must less than 4294967295
