Encryption standards

Syncfusion’s Essential PDF library offers comprehensive encryption support, spanning from fundamental to advanced standards, including RC4 40-bit, RC4 128-bit, AES 128-bit, AES 256-bit Revision 5, and AES 256-bit Revision 6 (PDF 2.0).

Protect with an owner password

The owner or master password alters the password and defines or limits access rights for the PDF document. The owner password is essential for accessing and viewing a PDF document set with one.

Protect with a user password

The user or open password is necessary to unlock and view PDF documents set with such permissions. PDFs protected by a user password are generally safer from unauthorized access and cracking attempts.

Document permissions

Through customization of permissions settings, you can grant or limit users' ability to carry out specific actions like content copying, printing, editing, and form field filling.
