Best way to validate unique value on encrypted data? |
Hello,
What is the best way to validate unique value on encrypted data column(e.g. Phone number)? I found this thread ( https://forum.codeigniter.com/thread-67598.html ) But, I don't think it's correct way beacuase even if you add the same string you will get another value. What is the best way? Please help me. |
