Yes, DESelect works with Data Extensions that contain encrypted fields, and this reflects in 3 places.
In the Available Fields sections, encrypted fields will be marked with a lock icon.
Creating a Target Data Extension
When creating a new target data extension, an additional option appears on newly created fields to mark a field as encrypted.
Note that when creating a new field from an existing encrypted field, this new field will also be encrypted.
When running a preview with encrypted fields, the preview screen in DESelect will show the columns of these encrypted fields not in plain values, but encrypted unreadable values.
