| For example, fn_n_initkey or fn_n_setkey may return zero (0), or fn_n_encrypt may return the input value unchanged. In addition, the sample SQL scripts will have no affect and will appear to not encrypt any data. This is not accompanied by an error message.
The most likely cause for this is a missing DLL.

Try reinstalling Encryptionizer and rebooting. TIP: You can use the Stored Procedure sp_n_ready, defined in add_sp.sql, to determine whether the APIs are present and active. E.g., declare @nResult Int exec @nResult = sp_n_ready if @nResult >= 0 -- APIs active and available else -- APIs not available |
