# Peer Identity Trust
#
# Validates downstream mTLS peer identity against a
# set of trusted peers. Requests without a verified
# peer identity or with an untrusted identity are
# rejected with 403.
#
# Requires mTLS on the listener. Each trusted peer
# entry matches on certificate digest, organization,
# or serial number. All configured fields on an entry
# must match.
#
# ⚠️  EXPERIMENTAL: This example uses the `spiffe` experimental feature.
# Not recommended for production use. Build with --features spiffe.
#
# Usage:
#   cargo run -p praxis-proxy --features spiffe -- \
#     -c examples/configs/security/peer-identity-trust.yaml
