Passwords, Security & Metadata

Name: IronPDF
Brand: Iron Software
Availability: InStock
Rating: 4.87 (307 reviews)

IronPDF allows the ability to encrypt, decrypt, modify metadata, and set certain permissions regarding annotations, copying and pasting content, form fields, and printing.

To open a password-protected PDF document, use the open method and provide the password as the second parameter. Setting metadata requires creating a new map and inputting key-value pairs corresponding to the metadata information. Pass the new metadata map into the overrideMetadata method to override the old metadata.

The removePasswordsAndEncryption method is used to remove any passwords from the document. The makePdfDocumentReadOnly method will make this PDF document read-only, encrypting content at 128 bits and disallowing copy and paste of content, annotations, and form editing.

Configure permissions by creating a permission object with permission settings and pass it to the setPermission method.

Lastly, the saveAs method can facilitate an object with ownerPassword and userPassword properties to be set respectively.
