The encryption systems used by the PDF specification is insecure because it uses symmetrical encryption/decryption the same passphrase/key is used to encrypt as well as fully decrypt the document. If you have to give the encryption/decryption passphrase/key to just read the document contents the reader can insert the passphrase/key into readily available 3rd party software that will remove the encryption entirely and completely unprotect the so called locked PDF document. The PDF encryption scheme is security through ignorance, if you ignore the inerrant weaknesses you FEEL more secure.

TK, Thank you for sharing your concerns about the encryption systems used in the PDF specification and Coolmuster PDF Locker. We appreciate feedback from our users, and we take security seriously.
You are correct that the PDF specification primarily employs symmetrical encryption/decryption, where the same passphrase or key is used for both encryption and decryption. This method, while widely used in PDF encryption, may present certain vulnerabilities if the passphrase/key falls into the wrong hands.
In Coolmuster PDF Locker, our goal is to provide a straightforward and user-friendly encryption solution for protecting PDF documents from unauthorized access. However, we understand that there may be limitations with symmetrical encryption.
To address these concerns, we would like to clarify that Coolmuster PDF Locker is best suited for situations where you trust the recipients with whom you share the encrypted PDF and the passphrase/key. It offers a simple and convenient way to protect sensitive information from casual access and accidental leaks.
For situations where stronger security is required, such as when sharing highly sensitive documents with unknown parties, we recommend considering more robust encryption methods, such as public-key cryptography and digital signatures. These methods can provide an added layer of security, making it significantly harder for unauthorized individuals to gain access to the contents of a locked PDF.
As a software provider, we constantly strive to improve our products and ensure the highest level of security possible. We will take your feedback into consideration for future updates and explore ways to enhance the encryption options in Coolmuster PDF Locker.
If you have any further questions or suggestions, please don't hesitate to reach out to our support team. Your input helps us make our products better and more secure for all users.
Thank you again for your valuable feedback.
