• Paranoia Text Encryption is a comprehensive text encryption application for iOS devices (iPhone/iPad/iPod) and macOS, developed by Paranoia Works. • Paranoia Text Encryption safeguards your notes, SMS messages, emails, social networking posts, cryptocurrency keys (seeds, mnemonics), and any other text from unwanted readers. • Simply copy and paste text to and from your favorite applications, or save it 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 use an unlimited number of passwords for any purpose—different files, tasks, people, etc. • The app guarantees robust security by encrypting data using strong encryption algorithms: Blowfish (448-bit), AES (256-bit), RC6 (256-bit), Serpent (256-bit), and Twofish (256-bit) ciphers. • Steganography: The application includes steganographic features, allowing you to conceal text or files within a JPEG image. Two algorithms are available: J-UNIWARD (content-adaptive, minimizes visual distortion, harder to detect) and F5 (matrix encoding, efficient embedding). The selected algorithm works with the chosen symmetric cipher to produce the final steganogram. • Key Encapsulation (KEM): Securely exchange encryption passwords using the post-quantum ML-KEM mechanism (NIST FIPS 203). Two parties can establish a shared password without ever transmitting it directly, with protection against future quantum computer attacks. ◆ Differences between Free and PRO versions: The PRO version offers additional encryption algorithms, specifically Threefish (1024-bit), SHACAL-2 (512-bit), and Paranoia C4 (2048-bit), which is a cascade of Threefish–Serpent–AES–SHACAL-2. 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 natively compatible with macOS (10.15 and later). Versions for other systems and platforms can be downloaded from the application homepage: https://paranoiaworks.mobi/download/. • An online (web-based) version, utilizing AES and client-side JavaScript, and other utilities are available at https://pteo.paranoiaworks.mobi
