This will allow you to encrypt fields while at rest in your database. Data is obfuscated from views but can still be edited.
I've added some hooks to encrypt data for certain fields when a form is created or updated. Works like a charm. See the attachment that shows the form entries. For this, I'm using the following two hooks. frm_add_entry_meta frm_after_update_entry When the information is displayed in a view, the encrypted content is replaced with "Encrypted". Working like a charm. See the attachment with a small view in the form of a list. I'm using the following hook. frmpro_fields_replace_shortcodes However, when I go to edit the form, I need to decrypt the field and present it back to the user. See the attachment with the encrypted blob in the form. I'm sure the hook is there, but I could really use a pointer to which one it is.
