HMAC SHA1 Digest in python

阅读更多关于 HMAC SHA1 Digest in python

问题 I'm using the Moves API to get some fitness data. Instead of querying the API on a regular basis I would like to use the storyline notifications. It works, I get a request from the API but I'm unable to verify the hmac sha1 signature provided in the request. The Documentation says: All notification requests are signed with Base64 encoded HMAC-SHA1 signature. The signature is calculated as HMAC_SHA1(<your client secret>,<request body>|<timestamp>|<nonce>), in other words the client secret as

Converting HMAC-SHA1 from node.js to Java

阅读更多关于 Converting HMAC-SHA1 from node.js to Java

问题 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

问题 I’m currently facing a big problem (Environment: .NET 4.5 Core): We need to protect a message with a key using a HMAC-SHA1 algorithm. The problem is that the HMACSHA1-class of the namespace System.Security.Cryptography and the namespace itself do not exist in .NET 4.5 Core, this namespace only exists in the normal version of .NET. I tried a lot of ways to find an equivalent namespace for our purpose but the only thing I found was Windows.Security.Cryptography which sadly does not offer a HMAC

HMAC SHA-512 generation discrepancies between iOS and javascript libraries

阅读更多关于 HMAC SHA-512 generation discrepancies between iOS and javascript libraries

问题 I am trying to replicate the Hmac generation behavior from my iOS app using SHA-512 algorithm referring to this link Objective-C sample code for HMAC-SHA1. For this purpose, I have tried using CrytoJS and jsSHA libraries to compute the Hmac using javascript code. I have found discrepancies in hmac values generated by these javascript libraries and the one that I have using my iOS code. Can someone help me understand what could I be doing wrong here? I have a feeling that I am messing up with

Wrong SHA1 from PHP & CF according to Amazon S3

阅读更多关于 Wrong SHA1 from PHP & CF according to Amazon S3

问题 Amazon consistently generates a different hash than PHP or CF, which causes a persistent "SignatureDoesNotMatch" error. According to the docs, GET requests [without REST headers] are signed as follows: Signature = URL-Encode( Base64( HMAC-SHA1( SecretAccessKey, UTF-8-Encoding-Of( StringToSign ) ) ) ); StringToSign = HTTP-VERB + "\n" + Content-MD5 + "\n" + Content-Type + "\n" + Expires + "\n" + CanonicalizedAmzHeaders + CanonicalizedResource; The example data: SecretAccessKey: wJalrXUtnFEMI

Unable to Generate HMac using Salesforce Crypto Class for Google Maps API

阅读更多关于 Unable to Generate HMac using Salesforce Crypto Class for Google Maps API

问题 My Company recently signed up for Google Maps API for business. To use the API, I need to generte a HMacSHA1 signature, and add it to my HTTP request. Unfortunately, somehow, I am not able to generate the right signature. For testing, I am using the values provided by google to ensure that the algorithm works fine and I get the right result. Here is the code: string url = 'maps/api/geocode/json?address=New+York&sensor=false&client=clientID'; string privateKey = 'vNIXE0xscrmjlyV-12Nj_BvUPaw=';

问题 I've spent past 6 hours implementing message signing algorithm.. It does not work AT ALL: This is PHP code to generate digest: $payload = "thisisanapple"; $signature = hash_hmac("sha1", $payload, "thisisarandomkey"); $data = base64_encode($signature); // YzExZWRmZDliMjQzNTZjNzhlNmE3ZTdmMDE3ODJjNmMxMmM4ZTllMQ== This is JS running on the Node.js server doing the same thing: var hmac = crypto.createHmac('sha1', "thisisarandomkey"); hmac.update("thisisanapple"); var signature = hmac.digest(

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 6 years ago .

Calculating an oauth signature

阅读更多关于 Calculating an oauth signature

I am trying something a little specific, namely trying to call a REST API. I have been following these instructions . I have been very careful to ensure that I am creating the "Signature base string" correctly. They define it to be created like this: (HTTP Method)&(Request URL)&(Normalized Parameters) You can double check if need be in my code, but I am very sure that it is fine. The problem that I am having is creating what they call the "oauth signature" and mine isn't matching theirs. They it should be created like this: Use the HMAC-SHA1 signature algorithm as defined by the [RFC2104] to
