AI Analysis

●●SolidDark HorseBig Brain

Byte-identical Kyber interop tests with Apple CryptoKit prove this isn't snake oil.

Strengths
  • FIPS-203 interop tests against Apple CryptoKit prove byte-identical Kyber implementation
  • Pure Swift with no C dependencies means easier audit and iOS integration
  • Honest about no third-party audit yet, invites scrutiny instead of hiding it
Weaknesses
  • Source-available license blocks reuse, limiting community security review and adoption
  • Post-quantum messaging already has Signal, Element, and other established competitors
