Onion Browser vs GPG Decrypt

Onion Browser is the original free and open-source Tor-powered web browser for iOS. Onion Browser helps you access the internet with more safety and privacy, and no extra cost to you. “The best Tor-related offering on iOS right now is Onion Browser” - The Daily Dot, October 14, 2015. Featured in: The New York Times, The Guardian, Salon, TechCrunch, Gizmodo, Boing Boing, Lifehacker, Macworld, The Daily Dot, & others. FEATURES: • Browse the internet over Tor: - Protect your privacy from website tracking - Secure your traffic from insecure wireless networks and ISPs - Access .onion sites that are only accessible over Tor. • Fight online tracking: block scripts and automatically clear cookies and tabs, based on your preferences. • And more privacy-enhancing features! DISCLAIMERS: - Web browsing is much slower than through a normal web browser or a VPN because your traffic is encrypted and relayed through the Tor network. - Onion Browser might not work on networks with advanced network restrictions. If the app does not connect, try using bridges (or a different type of bridge), force-quit, and then restart the app. - Use of Onion Browser is at your own risk; remember that sensitive data does not always belong on a mobile device. ** Onion Browser is free and open-source software.

This app is designed to allow you to read on your iPhone, files that have been encrypted on your Mac using GPG. The workflow is: 1. Encrypt a file on your Mac using GPG (AEAD - Authenticated Encryption with Associated Data, is not supported at the moment, see support page). 2. Transfer the encrypted file and your private key to your iPhone (using iCloud Drive, Dropbox, Google Drive, or any other cloud storage service) 3. Use this app to decrypt and view the file content on your iPhone This is particularly useful for securely accessing sensitive documents on your iPhone without storing the decrypted content permanently on the device. Features - Decrypt GPG-encrypted files - Support for private key authentication - Secure file handling with security-scoped resources - Display-only decryption (no persistent storage of decrypted content) Usage 1. Select the encrypted file you want to decrypt 2. Select your private key file 3. Enter the passphrase for your private key 4. Tap "Decrypt" to decrypt the file 5. The decrypted content will be displayed on screen. It is not saved to your device. GPG ([GNU Privacy Guard](https://gnupg.org/)) is a widely used open-source implementation of the OpenPGP standard. This app only supports asymmetric encryption (public/private key). It cannot decrypt files that were encrypted using symmetric encryption (password-only encryption). Using GPG on Mac OS - Install GnuPG: brew install gnupg - Generate a new GPG key: gpg --full-generate-key - Choose option 1 (RSA and RSA) - Choose 4096 bits - Choose 0 (key does not expire) - Enter your name and email - Enter a secure passphrase - Export your private key (required for decryption on iPhone): gpg --export-secret-keys --armor your-email@example.com > private_key.asc - Replace `your-email@example.com` with the email you used when creating the key - Enter your passphrase when prompted - The private key will be saved to `private_key.asc` - Transfer this file to your iPhone for use with the app - Encrypting a file: gpg --encrypt --recipient your-email@example.com your_file.txt - This creates `your_file.txt.gpg` - Transfer this encrypted file to your iPhone for decryption with the app Decrypting a file on Mac: gpg --decrypt your_file.txt.gpg > decrypted_file.txt - This will prompt for your private key passphrase - The decrypted content will be saved to `decrypted_file.txt` Transferring files to iPhone You can transfer the encrypted file and private key to your iPhone using various cloud storage services: - iCloud Drive - Dropbox - Google Drive - OneDrive - Or any other cloud storage service that provides iOS file access Security - All file operations use security-scoped resources - Passphrase is never stored - Files are copied to the app's documents directory for processing - Decrypted content is only displayed and not saved to the device - No persistent storage of sensitive information
