Read full description

• Paranoia Text Encryption PRO is a universal text encryption application for iOS (iPhone/iPad/iPod) and macOS by Paranoia Works. • Paranoia Text Encryption ensures the safety of your notes, SMS messages, 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-bit, SHACAL-2 512-bit, Paranoia C4 2048-bit (a cascade of Threefish, Serpent, AES, and SHACAL-2), Blowfish 448-bit, AES 256-bit, RC6 256-bit, Serpent 256-bit, and Twofish 256-bit ciphers. • 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 for entering the app itself. You may have an unlimited number of passwords for any purpose—different files, tasks, people, etc. • Steganography: The application offers 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 your chosen symmetric cipher to create 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 (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 them is exclusive to the PRO version. The PRO version also provides a key to activate the PRO versions of our 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, and other utilities are available at https://pteo.paranoiaworks.mobi

Verdict

The call

The clearest difference is price: DXCaptcha at Free against Paranoia Text Encryption PRO's $3.99. DXCaptcha also leads on iOS requirement (8.0 vs 14.5). Paranoia Text Encryption PRO's advantage is device support. On in-app purchases there is nothing between them.
