WoW_SRP

A standalone Rust library for the World of Warcraft flavor of SRP6. Has functionality for both the client and server.

Usage

Add the following to Cargo.toml:

[dependencies]
wow_srp = "0.6.0"

Or install with cargo edit:

cargo add wow_srp

Then read the documentation at docs.rs.

Examples

The wow_messages repo has examples that uses the wow_login_messages and wow_vanilla_messages library message definitions to showcase both crates.

Features

Two different arbitrary precision integer libraries can be used, either:

• num_bigint. A slow pure Rust implementation without external dependencies. This is enabled by default, and requires no opt in.

• rug. A fast wrapper around the GMP library with external dependencies, as described in the gmp_mpfr_sys documentation. This is enabled with the srp-fast-math feature and disabling default features. So instead of the above do this:

[dependencies]
wow_srp = { version = "0.6.0", default-features = false, features = ["srp-fast-math", "wrath-header"] }

The srp-fast-math feature leads to a 50% decrease in total time. It is highly recommended to enable this feature for production usage since it also theoretically has better security.

To see the performance difference on your setup you can run cargo bench for the default version, and cargo bench --features srp-fast-math --no-default-features for the srp-fast-math version.

The wrath-header feature gates features and dependencies related to wrath-header.

MSRV

wow_srp has a Minimum Supported Rust Version (MSRV) of 1.65.0. The MSRV may be increased in PATCH versions before wow_srp reaches 1.0.0 (MAJOR.MINOR.PATCH).
