Set ASE_BINARY_DISPLAY to preserve ciphertext integrity.
SET OPTION ASE_BINARY_DISPLAY = 'OFF'
When ASE_BINARY_DISPLAY is OFF (the default), the system leaves binary data unmodified, and in its raw binary form.
When ASE_BINARY_DISPLAY is ON, the system converts binary data into its hexadecimal string display representation. Temporarily set the option ON only if you need to show data to an end user, or if you need to export the data to another external system, where raw binary may become altered in transit.
