Could you build this?
Partial The UI and basic file management can be vibe-coded, but implementing custom cryptographic ratchets for Perfect Forward Secrecy alongside iOS Secure Enclave key attestation requires deep cryptographic rigor.
What it would actually take: Building this requires Swift/Objective-C integrating deeply with Apple's CryptoKit and Security framework (LocalAuthentication with `kSecAccessControlPrivateKeyUsage`). The hardest part is correctly implementing the Perfect Forward Secrecy (PFS) key derivation/ratcheting protocol without side-channel leaks or edge-case key loss. It demands strong applied cryptography expertise to avoid fatal security flaws.
