Multikey Patched Jun 2026

✅ Clean abstraction for entity lookup by alternate IDs ✅ Avoids nested maps or manual tuple hashing

A single hardware token that can store and use multiple independent key pairs (e.g., PIV slots, GPG keys for different purposes, FIDO2 resident keys). multikey

e.g., map["id"] = user; map["email"] = same user – usually implemented as separate hash tables under the hood. ✅ Clean abstraction for entity lookup by alternate

The use of multikeys provides several advantages and benefits, including: GPG keys for different purposes

✅ One device for many services/identities ✅ Reduces hardware cost and physical clutter ✅ Still tamper-resistant per key slot
