 To do so, Odoo can use the **SHA-256 algorithm** to create a unique fingerprint for each posted
 entry. This fingerprint is called a hash. The hash is generated by taking an entry's essential data

+(the values of the `name`, `date`, `journal_id`, `company_id`, `debit`, `credit`, `account_id`, and

 outputs a fixed size (256-bit) string of characters. The hash function is deterministic (:dfn:`the
