webauthn#

WebAuthn relying-party primitives for Zig.

This package is being built as a full Zig implementation of the server-side pieces needed for passkeys: challenge generation, browser option construction, registration verification, assertion verification, COSE key handling, and counter/flag semantics.

status#

Early library work. The first implemented surface covers challenge generation, base64url helpers, client data parsing, and authenticator data parsing.
