HTTP Signature Normaliztion Reqwest

An HTTP Signatures library that leaves the signing to you

Http Signature Normalization is a minimal-dependency crate for producing HTTP Signatures with user-provided signing and verification. The API is simple; there's a series of steps for creation and verification with types that ensure reasonable usage.

Usage

This crate provides extensions the RequestBuilder type from reqwest

First, add this crate to your dependencies

http-signature-normalization-reqwest = { version = "0.2.0", default-features = false, features = ["sha-2"] }
reqwest = "0.11"
sha2 = "0.9"
thiserror = "0.1"
tokio = "1"

Then, use it in your client

use http_signature_normalization_reqwest::prelude::*;
use reqwest::{header::DATE, Client};
use sha2::{Digest, Sha256};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let config = Config::default().require_header("accept");

    let digest = Sha256::new();

    let response = Client::new()
        .post("http://127.0.0.1:8010/")
        .header("User-Agent", "Reqwest")
        .header("Accept", "text/plain")
        .signature_with_digest(config, "my-key-id", digest, "my request body", |s| {
            println!("Signing String\n{}", s);
            Ok(base64::encode(s)) as Result<_, MyError>
        })
        .await?;

    let body = response.bytes().await.map_err(MyError::Body)?;

    println!("{:?}", body);
    Ok(())
}

#[derive(Debug, thiserror::Error)]
pub enum MyError {
    #[error("Failed to create signing string, {0}")]
    Convert(#[from] SignError),

    #[error("Failed to send request")]
    SendRequest(#[from] reqwest::Error),

    #[error("Failed to retrieve request body")]
    Body(reqwest::Error),
}
