iOS Image-Text Encryption App
Publicada el 2026-07-14
Descripción de la oferta
The goal is a lightweight iOS app with a clean, minimal interface that performs three core actions: 1. ingest one or more reference images, analyse them, and generate a reproducible mapping table; 2. accept a .txt file (or a .zip that contains one), apply the mapping, then run the data through an encryption layer; 3. save or share the resulting encrypted .txt file back to local storage / Files. I’m fine with Swift, Objective-C, or any cross-compiled framework as long as the final build runs smoothly on current iPhone models. For encryption I’m open-minded—AES, RSA, or a small custom algorithm are all acceptable if they fit the mapping logic and keep performance snappy. Deliverables • Xcode project with readable, well-commented source • Simple two-screen UI: import & mapping / encrypt & export • Mapping stored in-memory or sandboxed file, whatever is fastest • Clear README explaining build steps and how to extend the mapping or swap the cipher Acceptance will be based on: successful mapping creation from supplied sample images, encrypted output matching specification, and ability to decrypt when provided the key. If anything here needs clarification, let me know so we can lock requirements before you dive into code.
