Top Secret PDF Alternative Software for Enhanced Document Security
Secret PDF is a specialized software designed to enforce robust DRM controls on PDF documents, utilizing AES, random encryption algorithms, and public key technology. Its primary goal is to prevent unauthorized redistribution and access, addressing the common vulnerability of open and owner passwords being easily cracked. Secret PDF achieves this by creating a unique key-based system where users generate a local key, the owner produces a new key based on it, and the document can only be opened on the authorized device with the owner's public key. While highly effective, users often seek Secret PDF alternative solutions that offer different features, platforms, or pricing models. This article explores some of the best alternatives available for securing your PDF documents.
