aws-sign-v4

Use this crate to generate an AUTHORIZATION header for AWS Signature Version 4 services.

Example

Example usage with reqwest:

```rust const S3ACCESS: &str = "my-access-key"; const S3SECRET: &str = "my-secret-key";

[tokio::main]

async fn main() -> Result<(), reqwest::Error> { let datetime = chrono::Utc::now(); let url = "https://s3-bucket-url"; let mut headers = reqwest::header::HeaderMap::new();

headers.insert(
    "X-Amz-Date",
    datetime
        .format("%Y%m%dT%H%M%SZ")
        .to_string()
        .parse()
        .unwrap(),
);
headers.insert("X-Amz-Content-Sha256", "UNSIGNED-PAYLOAD".parse().unwrap());
headers.insert("host", "my-host".parse().unwrap());

let s = aws_sign_v4::AwsSign::new(
    "GET",
    url,
    &datetime,
    &headers,
    "us-east-1",
    &S3_ACCESS,
    &S3_SECRET,
);
let signature = s.sign();
println!("{:#?}", signature);
headers.insert(reqwest::header::AUTHORIZATION, signature.parse().unwrap());

let client = reqwest::Client::new();
let res = client
    .get(url)
    .headers(headers.to_owned())
    .body("")
    .send()
    .await?;

println!("Status: {}", res.status());
let body = res.text().await?;
println!("Body:\n\n{}", body);
Ok(())

} ```
