AI Analysis

MidShip ItBold Bet

Pure Swift Argon2 avoids FFI, but lacks libsodium's battle-tested audit history.

Strengths
  • Eliminates FFI boundary bugs like buffer overruns and use-after-free entirely.
  • RFC 9106 compliant ensures interoperability with existing standard verifiers today.
  • Swift 6 structured concurrency support enables modern async/await workflows natively.
Weaknesses
  • New implementation lacks the battle-tested audit history of libsodium wrappers.
  • Only three commits suggests early stage despite the production-ready claims.
