@suaveplan/crypto-cipher - AEAD cipher primitives with per-primitive selector layout: aes-256-gcm, chacha20-poly1305, xchacha20-poly1305. Noble + native impls selected at build time via crypto.config.ts. Nonces are caller-supplied; primitives never generate them internally.

Summary

Low-level AEAD (Authenticated Encryption with Associated Data) cipher primitives for the @suaveplan/crypto stack. Provides three algorithms — AES-256-GCM, ChaCha20-Poly1305, and XChaCha20-Poly1305 — each as a standalone subpath export for tree-shaking. Nonces are always caller-supplied: the package validates nonce length but never generates randomness internally, keeping the CSPRNG boundary in the caller's control. Implementation flavour ('noble' vs 'native') is selected at build time via crypto.config.ts; all Phase 0 implementations route to @noble/ciphers. Use @suaveplan/crypto for the high-level façade that combines nonce generation, engine selection, and structured error handling; use this package only when you need to supply your own cipher engine implementation.
