iCryptr

An iOS app that performs AES256 encryption on device utilizing Apple's CommonCrypto encryption library written in C.

The app allows users to pick files from the Files app or photos/videos from the Photos app and encrypts them in custom file format.

Note

This is a complete overhaul of my original iCryptr project which was a document-based app that could not handle large files.

RoadMap

• Get basic UI set up
• Rework original in-memory encryption service to work with streams
• Get file encryption/decryption working
• Add file thumbnail to encryption/decyption view
• Write README
• Get photo encryption working
  • (I need to see if I can get the Swift UI photo picker to not load large files into memory)
• Document the current file format in the README (rather than just in the comments)
• Add functionality to save (really move) the encrypted file to a different folder
• Add a progress indicator to the encyption/decryption page
• Consider adding a checksum of the original file to encrypted file format to verify that decryption was performed successfully
• Add a F.A.Q page that pops up when the ? button is tapped on the home page.
