Examples

Authorize the request:

request = {
    method : 'POST',
    uri : '/',
    headers : {
        Host : 'iam.amazonaws.com',
        'Content-Type' : 'application/x-www-form-urlencoded; charset=utf-8'
    },
    body : 'Action=ListUsers&Version=2010-05-08'
};

// the signer.authorize adds the 'x-amz-date' and 'Authorization' headers
// to the given request object
Signer = require('mazer').Signer,
signer = new Signer('wJalrXUtnFEMI/K7MDENG+bPxRfiCYEXAMPLEKEY'),
signer.authorize(request,
    'AKIDEXAMPLE/20110909/us-east-1/iam/aws4_request',
    '20110909/us-east-1/iam/aws4_request',
    'us-east-1', 'iam');

Calculate SHA256 Tree Hash of a file:

require('mazer').TreeHash.stream(fs.createReadStream(file),
    function (err, hash) {
        console.log(hash.toString('hex'));
    });
