Reliable, strong, safe. This is the iOS version of Guard7. Guard7 is a general purpose cryptography tool that can be used to encrypt, decrypt email and file, sign and verify files. It is the graphical frontend for the GNU Privacy Guard (GnuPG or GPG, http://www.gnupg.org) with additional features. Guard7 is an encryption and decryption system based on industry standard that can ensure the complete security of business negotiations or personal messages. It was developed to make the daily work with GnuPG simple and efficient. Why -------------------- The most difference between "public key cryptography" and normal "password protected cryptography" is that the first approach don't ask you to distribute any password to anyone or any unsafe place, e.g. email, chat app, or internet. And, you need an encryption tool that has industrial strength to protect your confidential information. Additional Features -------------------- Organise contacts in groups, then fast and efficiently organise dozens of recipients to send and receive file or email without setup recipients one by one and answer a bunch of boring questions and input repeat info again and again. Encrypt and decrypt a file just requires several taps, it's very simple, convenient and efficient. Common Tasks -------------------- a. list all contact groups, list all member of a group. b. encrypt and decrypt a file. c. set up recipients and encrypt an email, decrypt an encrypted email. d. sign and verify files. Thousands of people already benefited from the app in 2018 that year, but until today, they still..., what they are, then what they said what they doing. what the intention of the commenter is obvious. more maliciously attack, more affirmation of the app.

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
