Safe-Docs protects your sensitive documents and files with secure encryption. Documents protected by Safe-Docs cannot be opened, viewed, or printed. A password-protected login is required to encrypt or decrypt files. You decide which files to protect, and who can decrypt them. It protects any type of file. Word documents, Excel spreadsheets, even pictures, music, and video files; Just login and drag-and-drop files to encrypt or decrypt them. One process does both. Safe-Docs determines weather your file is already encrypted or not, and automatically encrypts or decrypts it. Permit or deny users the ability to encrypt or decrypt files independently. Keep track of which users are encrypting and decrypting files.
