我已经设置了attr_encrypted在我的应用程序中，每条记录都有单独的“iv”。
# Fields
User.e_name
User.e_name_iv
我正在尝试在用户表中搜索已知名称。我试过:
User.find_by_name("Joe Bloggs") # undefined method "find_by_name" for Class
User.where("name = ?", "Joe Bloggs").first # column "name" does not exist
User.where(:e_name => User.encrypt_name("Joe Bloggs")) # must specify an iv
如何通过名称查找记录？
最佳答案
虽然可以进行一些搜索，但不是很实用。您可能必须遍历每条记录，尝试每个相应的 IV，直到获得完全匹配为止，这取决于您拥有的记录数量，这不太实用。

搜索、加入等
While choosing to encrypt at the attribute level is the most secure solution, it is not without drawbacks. Namely, you cannot search the encrypted data, and because you can't search it, you can't index it either. You also can't use joins on the encrypted data. Data that is securely encrypted is effectively noise. So any operations that rely on the data not being noise will not work. If you need to do any of the aforementioned operations, please consider using database and file system encryption along with transport encryption as it moves through your stack.
