This encryption includes 128-bit or 256-bit protection to make the document highly encrypted. These algorithms work against the brute force attack to shield the PDF. The purpose of imposing such advanced protection is to disable actions like editing, text copying, and document printing.
  • Complex Password Combination: The encrypted PDFs are created with a strong password. It mainly includes the blend of characters such as uppercase, lowercase, numbers, and special characters. Making a longer password encryption prevents hackers from cracking the decryption key. It helps to secure privileged information like contracts, legal documents, and even financial statements.
