A standalone implementation of the AWS Signature V4 request signing algorithm
@aws-sdk/signature-v4 is a package from the AWS SDK for JavaScript that provides functionality to sign AWS requests using the Signature Version 4 signing process. This is essential for securely making authenticated requests to AWS services.
Signing HTTP Requests
This feature allows you to sign HTTP requests to AWS services using the Signature Version 4 signing process. The code sample demonstrates how to sign a GET request to an S3 bucket.
const { SignatureV4 } = require('@aws-sdk/signature-v4');
const { Sha256 } = require('@aws-crypto/sha256-js');
const { HttpRequest } = require('@aws-sdk/protocol-http');
const signer = new SignatureV4({
service: 's3',
region: 'us-east-1',
credentials: {
accessKeyId: 'AKID',
secretAccessKey: 'SECRET'
},
sha256: Sha256
});
const request = new HttpRequest({
method: 'GET',
hostname: 'examplebucket.s3.amazonaws.com',
path: '/exampleobject'
});
signer.sign(request).then(signedRequest => {
console.log(signedRequest);
});Presigning URLs
This feature allows you to generate presigned URLs for AWS services, which can be used to grant temporary access to resources. The code sample demonstrates how to presign a URL for an S3 object.
const { S3RequestPresigner } = require('@aws-sdk/s3-request-presigner');
const { HttpRequest } = require('@aws-sdk/protocol-http');
const { Hash } = require('@aws-sdk/hash-node');
const { formatUrl } = require('@aws-sdk/util-format-url');
const presigner = new S3RequestPresigner({
credentials: {
accessKeyId: 'AKID',
secretAccessKey: 'SECRET'
},
region: 'us-east-1',
sha256: Hash.bind(null, 'sha256')
});
const request = new HttpRequest({
method: 'GET',
hostname: 'examplebucket.s3.amazonaws.com',
path: '/exampleobject'
});
presigner.presign(request).then(presignedUrl => {
console.log(formatUrl(presignedUrl));
});The aws4 package is a lightweight library for signing AWS requests with Signature Version 4. It is simpler and has fewer dependencies compared to @aws-sdk/signature-v4, making it a good choice for smaller projects or environments with limited resources.
The aws-signature-v4 package is another library for signing AWS requests using Signature Version 4. It is designed to be compatible with both Node.js and browser environments, similar to @aws-sdk/signature-v4, but it may not be as feature-rich or tightly integrated with the AWS SDK.
