Paranoia Text Encryption Lite vs AEStego

• 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

AEStego — Secure Image Steganography AEStego allows you to securely embed data inside images using advanced steganographic techniques and AES-256 encryption. Keep sensitive information concealed within ordinary photos while maintaining image quality and full offline privacy. Unlike simple “hide text” apps, AEStego is built for serious privacy. It combines authenticated AES encryption, compression, and structured data integrity verification to ensure your embedded content remains secure and tamper-resistant. Advanced Encryption • AES-256-GCM authenticated encryption • Optional hardware-bound Secure Enclave mode • Hybrid key derivation for strong password protection • Integrity verification with SHA-256 validation Your data remains encrypted and authenticated before being embedded. Professional Steganography • Pseudorandom bit distribution • Lossless PNG and TIFF support • Automatic JPEG conversion to lossless format • Capacity validation before embedding • No visible image distortion The carrier image remains visually unchanged while securely holding your data. Smart Compression • Compression applied before embedding • Works with encrypted and unencrypted payloads • Reduces detectable patterns • Efficient storage inside images Embed Text or Files AEStego supports embedding: • Text messages • Documents • PDFs • Images • JSON • ZIP files • Any binary file Extracted payloads are restored byte-for-byte with integrity verification. Secure Extraction • Detect embedded payloads • Automatic structure validation • Password-protected extraction (if encrypted) • Save or share recovered data • Integrity and authentication verification If an image does not contain valid embedded data, AEStego safely reports it. Privacy First • 100% offline operation • No tracking • No analytics • No cloud dependency • No account required Your data never leaves your device. Designed for Professionals AEStego is ideal for: • Privacy-conscious users • Security researchers • Journalists • Developers • Digital security enthusiasts Clean interface. Technical accuracy. No gimmicks. How It Works Select an image Select text or file Enable encryption (optional) Embed data Extract when needed Simple workflow, powerful protection. AEStego combines modern encryption with advanced steganography to provide a secure, professional-grade tool for discreet data concealment. Stay private. Stay secure.
