The Apryse CLI streamlines secure document pr If the output document is protected with an owner password (also known as master or permission password), it is possible to adjust standard PDF permissions using the following options: {% tabs %} {% tab title="Shell" %} {% code lineNumbers="true" %} ```sh +-----------------------+-----------------------+-----------------------+ | Option | Parameter | Description | +=======================+=======================+=======================+ | -d or \--disable | e.g. to disable any | This option accepts a | | | changes to the | string of permissions | | | document specify --d | flags that should be | | | m | disabled. | | | | | | | e.g. to disable | The permission string | | | printing and content | may include the | | | extraction specify | following flags: | | | --d phxdcm | | | | | - a - All | | | | permissions. | | | | | | | | - p - Printing. | | | | | | | | - m - Changing the | | | | document. | | | | | | | | - c - Content | | | | copying or | | | | extraction. | | | | | | | | - o - Commenting. | | | | | | | | - f - Filling of | | | | form fields. | | | | | | | | - x - Content | | | | extraction for | | | | accessibility. | | | | | | | | - s - Document | | | | assembly. | | | | | | | | - h - High quality | | | | printing. | +-----------------------+-----------------------+-----------------------+ | -e or --enable | e.g. to enable | A string of | | | commenting: -e o | permissions flags | | | | (see \--disable | | | | option above) that | | | | can be enabled. If | | | | there is a conflict | | | | with one of the flags | | | | in the \'disable\' | | | | option, the | | | | permission is not | | | | granted. | +-----------------------+-----------------------+-----------------------+ ``` {% endcode %} {% endtab %} {% endtabs %} Permissions for the document can be set separately from access to the document which is controlled using the user password. With password security, it is possible to require different passwords to open (i.e. user password) and modify (i.e. owner password) the document. This means that you can allow one set of users to open the document, and another, possibly smaller set, to make unrestricted changes. Users without the owner password can only make the changes allowed when the document was prepared.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.apryse.com/cli/pdfsecure/options/permission.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
