Requests Diffie-hellman parameters for key exchange

Parameters:

Name	Type	Required	Description
nonce	CLICK ME int128	Yes	Random number for cryptographic security
server_nonce	CLICK ME int128	Yes	Random number for cryptographic security, given by server
p	CLICK ME bytes	Yes	Factorized p from pq
q	CLICK ME bytes	Yes	Factorized q from pq
public_key_fingerprint	CLICK ME long	Yes	Server RSA fingerprint
encrypted_data	CLICK ME bytes	Yes	Encrypted key exchange message

Return type: Server_DH_Params

Can bots use this method: YES

Example:

if (!file_exists('madeline.php')) {
    copy('https://phar.madelineproto.xyz/madeline.php', 'madeline.php');
}
include 'madeline.php';

// !!! This API id/API hash combination will not work !!!
// !!! You must get your own @ my.telegram.org !!!
$api_id = 0;
$api_hash = '';

$MadelineProto = new \danog\MadelineProto\API('session.madeline', ['app_info' => ['api_id' => $api_id, 'api_hash' => $api_hash]]);
$MadelineProto->start();

$Server_DH_Params = $MadelineProto->req_DH_params(['nonce' => int128, 'server_nonce' => int128, 'p' => 'bytes', 'q' => 'bytes', 'public_key_fingerprint' => long, 'encrypted_data' => 'bytes', ]);

Or, if you're using the PWRTelegram HTTP API:

As a bot:

POST/GET to https://api.pwrtelegram.xyz/botTOKEN/madeline

Parameters:

• method - req_DH_params
• params - {"nonce": int128, "server_nonce": int128, "p": "bytes", "q": "bytes", "public_key_fingerprint": long, "encrypted_data": "bytes", }

As a user:

POST/GET to https://api.pwrtelegram.xyz/userTOKEN/req_DH_params

Parameters:

nonce - Json encoded int128

server_nonce - Json encoded int128

p - Json encoded bytes

q - Json encoded bytes

public_key_fingerprint - Json encoded long

encrypted_data - Json encoded bytes

Or, if you're into Lua:

Server_DH_Params = req_DH_params({nonce=int128, server_nonce=int128, p='bytes', q='bytes', public_key_fingerprint=long, encrypted_data='bytes', })
