How to Encrypt a PDF Without Acrobat | Secure PDF Encryption | PDF Protection

Secure Alternatives to Acrobat PDF Encryption Software

Adobe Acrobat encryption has long been known to have security flaws. Fortunately, there are better alternatives available, such as VeryPDF DRM Protector, which provides a much more robust solution for protecting your PDF documents from unauthorized sharing and misuse.

Why Adobe Acrobat Encryption is Not Secure

Adobe Acrobat has had encryption since the 1990s, but its implementation has often been weak. Early versions were quickly cracked, and even today, Acrobat’s encryption can be bypassed with various tools, making it unsuitable for true document security.

Better PDF Encryption Methods

Common Free PDF Encryption Websites

Many free online PDF encryption tools provide protection similar to Adobe Acrobat. However, they typically rely on password-based security, which is easily cracked. Since passwords can be shared, these methods do not effectively prevent unauthorized access.

PDF Certificate Encryption

Certificate-based encryption is an improvement over passwords because private keys are harder to share. However, once a document is decrypted, there is nothing stopping users from copying or distributing it. Managing certificates can also be time-consuming and impractical for many organizations.

AES PDF Encryption Algorithms

AES (Advanced Encryption Standard) is the gold standard for PDF encryption. AES encryption is widely used because of its high level of security and efficiency. There are two commonly used AES key lengths for PDF encryption:

AES 128-bit: This encryption level provides a strong balance between security and performance. Cracking a 128-bit AES encrypted document would take longer than the current age of the universe using brute-force attacks.
AES 256-bit: This is an even stronger encryption method, offering additional resistance against brute-force attacks and quantum computing threats. While slightly slower than AES 128-bit, it provides higher security assurance.

VeryPDF DRM Protector uses AES encryption in combination with DRM controls to ensure that PDF files remain protected even after they have been opened.

Why Choose VeryPDF DRM Protector?

Unlike traditional encryption, VeryPDF DRM Protector offers true security by using encryption combined with DRM (Digital Rights Management) controls. It protects PDFs not just during transmission and storage but even after they are opened.

How to Encrypt a PDF File Using VeryPDF DRM Protector

Encrypting your PDF with VeryPDF DRM Protector is simple and highly secure. Follow these steps:

Go to VeryPDF DRM Protector Online.
Upload your PDF file and select “Make Secure PDF”.
Choose restrictions such as preventing copying, printing, or screenshots.
Press “Publish” to encrypt and apply DRM protections.
Add users and control document access via the Safeguard Admin System.
Distribute your protected PDF securely—only authorized users can view it.

Why VeryPDF DRM Protector is the Best PDF Encryption Software

VeryPDF DRM Protector goes beyond basic encryption by adding strong DRM controls:

Prevents unauthorized copying, editing, and printing.
Blocks screenshots and screen recording.
Allows remote document access management.
Works even after a PDF has been downloaded.
Protects confidential documents from leaks.

FAQs

What is the best encryption algorithm for PDFs?

AES (Advanced Encryption Standard) is the best encryption algorithm for PDFs. It is used globally for securing sensitive data and is recommended by security experts.

Is AES 128-bit encryption secure enough?

Yes, AES 128-bit encryption is extremely secure for most purposes. It is virtually impossible to crack using brute-force attacks within a realistic timeframe.

Should I use AES 256-bit instead of AES 128-bit?

If you need the highest level of security, AES 256-bit encryption is preferable. It offers better protection against potential future quantum computing threats.

How does VeryPDF DRM Protector prevent unauthorized sharing?

VeryPDF DRM Protector not only encrypts your PDF but also applies DRM restrictions, preventing unauthorized users from accessing, copying, printing, or sharing your documents.
