App: Paranoia Text Encryption PRO
Developer: Frantisek Dvorak
Genres: Dienst­programme, Soziale Netze

• Paranoia Text Encryption PRO is a universal text encryption application for iOS (iPhone/iPad/iPod) by Paranoia Works.
• Paranoia Text Encryption ensures the safety of your notes, SMSs, emails, social networking posts, cryptocurrency keys (seeds, mnemonics), and any other text from all unwanted readers.
• The app offers true security, encrypting data using the strongest encryption algorithms available: Threefish 1024 bits, SHACAL-2 512 bits, Paranoia C4 2048 bits (a cascade of Threefish, Serpent, AES, and SHACAL2), Blowfish 448 bits, AES 256 bits, RC6 256 bits, Serpent 256 bits, and Twofish 256 bits ciphers.
• Simply copy and paste text to and from your favorite applications, or save to a file for future use.
• This app does not function as a "Vault application". Instead, a password is set for the current encryption/decryption session, not to enter the app itself. You may have an unlimited number of passwords for any purpose—different files, tasks, people, etc.
• Steganography: This application offers steganographic features, allowing you to conceal text within a JPEG image. It uses the F5 steganographic algorithm in combination with your chosen symmetric cipher algorithm to create a final steganogram (JPEG image).

◆ Differences between Free and PRO versions: The PRO version offers additional encryption algorithms, specifically Threefish 1024bit, SHACAL-2 512bit, and Paranoia C4 2048bit (which is a cascade of Threefish–Serpent–AES–SHACAL2). While the free version can decrypt data encrypted by these advanced algorithms, the ability to encrypt data using these algorithms is exclusive to the PRO version. The PRO version also provides a key to activate the PRO versions of desktop applications: Paranoia File & Text Encryption for PC, Paranoia Text Encryption for PC and S.S.E. File Encryptor for PC.

• The application is directly compatible with macOS (10.15 and later). Versions for other systems and platforms are available on the application's homepage (download section - https://paranoiaworks.mobi/download/).
• An online (web-based) version, utilizing AES and client-side JavaScript, is available at https://pteo.paranoiaworks.mobi.
