This is an example project demonstrating how to use PGP encryption and decryption in an iOS app. It uses the Objective-C implementation of the OpenPGP standard, OpenPGP.framework.

• Manage Keychain:
  • Generate new keys: public and private keys
  • Import key from local file url
  • Import key from clipboard
• Signing the message with private key, output with the signature
• Verify if signature was signed with one of the given keys.
• Get the plain text from the signed message
• Encrypt data
• Decrypt PGP encrypted data
• Others:
  • Export keys to local files (*.gpg)

List Keys	Generate New Key	Key Detail
Signing	Verify Signing
Encryption	Decryption	Settings

• Save keys to Core Data
• Optimize UI: Add empty background UI for List Keys screen if it have no key in the app
• Delete specific Key in List Keys screen
• Delete all keys

• iOS 15.0+
• Xcode 11+

• To install the app, clone the repository and open the PGP-example.xcworkspace file in Xcode.

The cryptographic library used by PGPro, ObjectivePGP, has undergone a complete security audit from Cure53.

This project uses the ObjectivePGP library developed by Marcin Krzyżanowski. Thereby it uses software developed by the OpenSSL Project for use in the OpenSSL Toolkit.
