问题 The scenario is that I have a JS script that creates a HMAC for a user provided input and I want to compute the same HMAC for the same input using python. To make things clearer, consider the following JS and Python code snippets.

Issues Placing a Trade with Binance API using Python

谁都会走 提交于 2021-02-10 12:13:26
问题 I am trying to place a trade on the US version of Binance API without the use of external libraries. I can successfully get prices and display my account balance using GET requests and urllib . The first example code works and I can pass my API_KEY and SECRET_KEY without issues (those values are private, they aren't displayed here and are located in settings.py ). Placing a trade requires POST and I'm not sure where I went wrong, my POST requests don't work but GET requests work fine. To my

Decrypting signature and Veryifying JWT

南笙酒味 提交于 2021-02-07 23:25:34
问题 I understand that there exist other libraries which make my life easier to work with JWT (in node.js). In this case, I am using "crypto-js" to learn JWT in a manual way. The following gives me the token: var header = { "alg": "HS256", "typ": "JWT" }; var wordArrayHeader = CryptoJS.enc.Utf8.parse(JSON.stringify(header)); var base64Header = CryptoJS.enc.Base64.stringify(wordArrayHeader); var payload = { "sub": "1234567890", "name": "John Doe", "admin": true }; var wordArrayPayload = CryptoJS

How can I calculate an AWS API signature (v4) in python?

问题 I'm attempting to generate a signature for an Amazon Glacier upload request, using the example requests and example functions provided by the AWS documentation, but I can't make it work.

hmac hash mismatch in PHP and Go

痞子三分冷 提交于 2021-02-05 07:17:35
问题 I am trying to connect to an API that uses an outdated hmac hash authentication mechanism for the API's. For an instance: $signature = hash_hmac('sha256', $string_to_sign, $api_sec); vs the one generated in Go: h := hmac.New(sha256.New, []byte(authSecret)) h.Write([]byte(stringToSign)) signature := hex.EncodeToString(h.Sum(nil)) When I use the same stringToSign($string_to_sign) and same authSecret($api_sec) the signature generated with Go results as an invalid signature for the API. But if I
