Features
Read full description

Please run ShredIt Mobile for iOS in the foreground. Running it in the background will take a *very* long time even if you don't have a lot of free space. If speed is important, make sure to choose no government standards and only a single overwrite of a fixed pattern. Following these steps will give you the best performance experience with the ShredIt App. ShredIt Mobile for iOS will write a large file to internal storage of your iOS device. This large file will fill up all the free space on your device and then it will be deleted to free up all the space again. You can configure ShredIt for iOS to perform this multiple times with different patterns. Because the file is unlinked when it is created, if something happens, like your device runs out of battery, the space is automatically returned by iOS. ShredIt Mobile will report both the size of the file it has created and how long it takes to fill it up.

• 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. File Encryptor for PC • We greatly appreciate your feedback, including suggestions for improvement and reports of technical problems.
