• Paranoia File Encryption is a universal file encryption application for iOS (iPhone/iPad/iPod), brought to you by Paranoia Works. It securely encrypts your private and confidential files or entire folders. P.F.E. works like an archiver, creating a new .enc file after encryption. The original file(s) can be deleted or wiped after the encryption process is completed. This can be done manually or set to be done automatically. • The app ensures real security as data is encrypted using the strongest encryption algorithms: Blowfish 448bit, AES 256bit, RC6 256bit, Serpent 256bit, Twofish 256bit, Threefish 1024bit, SHACAL-2 512bit, and Paranoia C4 2048bit ciphers are available. • Steganography: The application offers steganographic features, allowing you to conceal files within a JPEG image. Two algorithms are available: J-UNIWARD and F5. The selected algorithm works with your chosen symmetric cipher to create the final steganogram. • Versions for other systems and platforms are available on the application's homepage (download section - https://paranoiaworks.mobi/download/). • The AES web version is available at: https://pteo.paranoiaworks.mobi/paranoia-file-encryption/ • Free / PRO version differences: The PRO version contains more algorithms - specifically, Threefish 1024bit, SHACAL-2 512bit, and Paranoia C4 2048bit (which is a cascade of Threefish–Serpent–AES–SHACAL2). The free version can decrypt data encrypted by these advanced algorithms, but encryption is exclusive to the PRO version. In addition, the PRO version allows the selection of multiple files and their batch processing. It also provides a key to activate the PRO version of the desktop application: Paranoia File & Text Encryption for PC, Paranoia Text Encryption for PC and S.S.E.
