By default, data in the data file is not encrypted in v15 or v17. You can open a data file with a text editor and read some of the data. It’s stored as UTF-16 so it’s not clearly readable as each character takes 2 bytes so my name would look like “T?i?m ?N?e?v?e?l?s?”. You could implement your own encryption at a field level using some of the tools 4D provides for encrypting blobs. But v18 is going to provide strong data file encryption systems that can be applied on a table-by-table basis. The record data is encrypted with a strong key. Even index data and data written to journal files are encrypted. And of course 4D backup have the encrypted data. 4D is doing their first presentation of table level data file encryption at the 4D World Tour. So it’s all very new, and not yet available. It’s a v18 feature. I think they are releasing it in a v17 R release too.
