If the value for a encrypt field is too long the webshop crashed in the decrypt process. This error comes when the field in the table is not big enough. The stored procedure cut the encryption string. Decryption of this value is then not possible. if you change the stored procedure and the  field length the bux is fixed. We use the nopcommerce version 1.6.
Is this bug in nopcommerce 1.7, with new entity Framework, still there?
