I'm trying to write python authentication bot for: https://comkort.com/page/private_api There is no full php example. I'm guess somebody could put it here. There is only snippet of php code: $query_string = http_build_query($_POST, '', '&'); $ethalon_sign = hash_hmac("sha512", $query_string, $api_secret_key); How to write authentication on python with hash_hmac sha512 ? I want to extract my open orders POST https://api.comkort.com/v1/private/order/list . My current variant is: import hashlib import hmac import requests import time privateKey = b'myprivatekey' publicKey = 'my public key' url =

We are a large university and have a single team account in apple itunes provisioning portal. We have serval different groups developing iOS apps, which will be published under the team account (university name). It seems apple only allows to create one distribution certificate. To publish apps, each group will need the private key to sign the app. If we choose to share the private key among all groups, is there any concern? Someone also suggested revoking the current certificate. I understand it will not affect the current apps in store. But others will have to revoke the certificate again

I have a problem to decrypt a message usgin X.509 Certificate. I generate my certificate with makecert with this options: makecert -r -pe -n "CN=MyCertificate" -ss CA -sr CurrentUser -a sha1 -sky signature -cy authority -sv CA.pvk CA.cer And the PrivateKey was "mypassword". My problem is when I want to decrypt a message encrypt with previous certificate in c#. I found this class http://blog.shutupandcode.net/?p=660 , but in the X509Decrypt method allways the PrivateKey is null. public static byte[] X509Decrypt(byte[] data, string certificateFile, string password) { // load the certificate and

How to get the related public-key object java.security.PublicKey out of a private-key Object java.security.PrivateKey in the RSA cryptosystem. Java is able to create a public key by using the modulus and exponent: RSAPublicKeySpec keySpec = new RSAPublicKeySpec(modulus, exponent); kf.generatePublic(keySpec); So we need to extract these values out of the private key: KeyFactory kf = KeyFactory.getInstance("RSA"); RSAPrivateKeySpec priv = kf.getKeySpec(privateKey, RSAPrivateKeySpec.class); The RSAPrivateKeySpec -Object now contains the modulus we need, but the exponent is not the one we need for

I have two AsymmetricAlgorithm objects that contain an RSA Private and RSA Public key. The private key was retrieved out of the Windows-MY keystore and the Public key from a user's certificate. How can I use these keys along with RSACryptoServiceProvider to encrypt data using the RSA algorithm in C#? In other words, how can I specify that I want to use keys that I already have? #region "RSA Encrypt/Decrypt" public string RSAEncrypt(string str, string publicKey) { //---Creates a new instance of RSACryptoServiceProvider--- try { RSACryptoServiceProvider RSA = new RSACryptoServiceProvider(); //--
