Error when saving Data

[MuhammadShahryiar]

Unsupported lookup 'exact' for EncryptedCharField or join on the field not permitted, perhaps you meant exact or iexact?

Please see #10

Given the nature of data encryption, anything other than isnull is not query-able. This is a side affect of encrypting the data in the first place, as the output will change even when the input does not.
