Overview

hickory-proto is a safe and secure low-level DNS library. This is the foundational DNS protocol library used by the other higher-level Hickory DNS crates.

Unless you want to manipulate the DNS packets directly, it is likely not the library you want. For higher-level interfaces, refer to the hickory-server, hickory-resolver library crates instead.

Cryptography provider

Features requiring cryptography require selecting a specific cryptography provider. See the project README for more information.

DNSSEC

In order to use DNSSEC you must enable a cargo feature corresponding to your desired cryptography provider:

• dnssec-aws-lc-rs
• dnssec-ring

Other crate features

• text-parsing - support for reading text-based zone files.
• serde - enable serde serialization support.
