NguyenKey vs Paranoia File Encryption PRO

■ Background of the App NguyenKey is a new Vietnamese keyboard app designed to overcome the challenges of traditional Telex and VNI methods — such as the hassle of memorizing key combinations and the number of taps required. By separating the keyboard into dedicated Consonant and Vowel screens with automatic switching and multi-letter keys, NguyenKey enables a natural typing rhythm with significantly fewer taps. ■ Key Features • Automatic Screen Switching for Rhythmic Typing Consonant and vowel screens are separated and switch automatically as you type, allowing for a seamless, rhythmic input experience. • Multi-Letter Keys to Reduce Taps Consonant keys combining up to 3 letters and diphthongs available with a single tap greatly reduce the number of taps needed per word. • Intuitive Tone Input — No Memorization Required Simply select one of the 6 tone shift keys before choosing a vowel. There is no need to memorize complex key combinations. • Compact 6×7 Layout Optimized for One-Handed Use Specifically designed for smartphones, the compact 6×7 grid makes one-handed typing easy and comfortable. • Convenient Shift Key Options Includes a White Shift Key (capitalizes the next character) and a Black Shift Key (Caps Lock). • Phonetic Symbols (IPA) Display Optionally display International Phonetic Alphabet (IPA) symbols on consonant and vowel keys. Supports both Northern (Standard) and Southern dialects. It can also display pronunciation conditions, such as when the mouth needs to be closed after a final consonant. • 4 Typing Modes Easily switch between Vietnamese, English, Numbers, and Symbols modes. ■ Typing Example: "Việt" 1. On the consonant screen, tap the White Shift Key to capitalize, then tap "V". 2. The app automatically switches to the vowel screen. Select the underdot tone. 3. Tap the tone-marked diphthong "iệ". 4. The screen automatically switches back to the consonant screen. Tap "t" to finish. ■ Initial Setup 1. Go to iOS "Settings" > "General" > "Keyboard" > "Keyboards" > "Add New Keyboard…". 2. Select "NguyenKey" to enable it. 3. While typing in any app, press and hold the Globe icon on the keyboard and select "NguyenKey". ■ Compatibility • Requires iOS 15.6 or later / iPadOS 15.6 or later • Compatible with iPhone and iPad ■ Privacy & Security NguyenKey does not transmit or collect what you type through external servers. ■ Support & Contact Support Site: https://superscript.sakura.ne.jp/ Email: [snowysap@gmail.com](mailto:snowysap@gmail.com) Created by: Takayuki Imai

• 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.
