hmac

i have tried several links from stackoverflow to get HmacSHA256 with key to work with java, but i always get func check(body: String) -> String { let hash = body.hmac(HMACAlgorithm.sha256, key: Router.sigKey) print("SIG: " + Router.sigKey) print("result of hash. \(hash)") return hash } This function returns hash with key from given String. Key was: 0393e944ee8108bb66fc9fa4f99f9c862481e9e0519e18232ba61b0767eee8c6 String was: example Result is: 27effb76c97022497e25d3a5d7e823462f212a82d9ebba35f179071568b0c335 When i use this website to check if my SHA256 is good with the same key, it returns same

This question already has an answer here: CommonHMAC in Swift 10 answers I'm trying to encrypt data to send to the API. The API requires the data to be sent as hmac_sha512 encrypted hash. I've found various examples of how it possibly could have been done for sha1 and others (not sha512 ) and also in older versions of Swift. None of the examples that I tried work for swift 3.1 Any help in the right direction will be appreciated. Edit: In PHP, I successfully send it using: $sign = hash_hmac('sha512', $post_data, $this->secret); Edit 2: I did add briding header , I don't know what to do next! As

I have been tasked with converting some existing piece of node.js code to Java. I think I'm well on my way, but I'm kind of stuck right now. The output of the methods do not seem to match. What I'm doing is creating a SHA-1 signature based on a query string. This query string contains some query-related data (not relevant for this question) and an API key. Important The api_secret string in node.js is equivalent to Config.API_SECRET in Java. Example query string (these are equal in the node.js and Java program): /events?festival=imaginate&pretty=1&size=100&from=0&key=SOME_KEY Actual code The

I'm developing with localbitcoin API and i am using path “/api/dashboard/closed/” and this is my code: <?php function localbitcoinsquery($path, $nonce,array $req = Array()) { global $random; $key='mykey'; $secret='secretkey'; if ($req) { $get=httpbuildquery($req); $path=$path.'?'.$get; } $postdata=$nonce.$key.$path; $sign = strtoupper(hashhmac('sha256', $postdata, $secret)); $headers = array( 'Apiauth-Signature:'.$sign, 'Apiauth-Key:'.$key, 'Apiauth-Nonce:'.$nonce ); $ch = null; $ch = curlinit('https://localbitcoins.com'.$path); curlsetopt($ch, CURLOPTRETURNTRANSFER, true); curlsetopt($ch,

I'm trying to publish an app on Shopify marketplace by following this documentation. And I'm stuck on step-3 of the oauth documentation wherein you have to do 'HMAC Signature Validation'. Documentation states that you have to process the string (specified below) through HMAC-SHA256 using app's shared secret key. String = "shop=some-shop.myshopify.com&timestamp=1337178173" I'm trying to implement the steps using Java. Following is gist of the code that I have used. private static final String HMAC_ALGORITHM = "HmacSHA256"; String key = "hush"; String data = "shop=some-shop.myshopify.com

I'm creating a script that will access AWS services using GAS. I'm using the hashing functions in the Utilities library for all the hashing that is required to create a v4 signature. These functions appear to be able to successfully hash data once, but trying to pass in hashed data into an argument yields incorrect results. Anyone else run into this issue and figure it out? I know there is something weird going on with Utilities.computeHmacSha256Signature( input, key ) , because the arguments can only be byte arrays or strings, and I am passing in combinations of the two. However, when I try
