Android HttpClient Digest Authentication Authorization header “nc” hard-coded

问题 We try to send several requests to target server in one HttpClient (one session). The target server will first authenticate all requests with digest authentication (based on MD5-sess). The result shows that only first access is successful. The following accesses are rejected by server because server treats later accesses as replay attack as the "nc" value is always "00000001". It seems Android HttpClient hard-coded digest authorization header attirbute "nc" to "00000001"? Any way for client

Node http requests are executing out of order causing problems with an API using a nonce value

由 て烟熏妆下的殇ゞ 提交于 2019-12-13 18:51:53
问题 I am making http requests to an external API that requires each request to have an ever increasing nonce value. The problem I am experiencing is that even though the requests are submitted in order, they are not getting popped off the call stack in order (presumably). I am using the request library. A portion of my helper method looks like this: Api.prototype.makeRequest = function(path, args, callback) { var self = this; var nonce = null; var options = null; // Create the key, signature, and

secure api communication between two backend servers

由 孤人 提交于 2019-12-12 23:14:41
问题 I need to secure the communication between two backend servers. A simple api key was rejected by our security policy since attackers would be able to intercept it. IP restriction also, because it could be spoofed. I was suggested to use a nonce, but wouldn't this mean that a request requires two roundtrips? I don't really like the idea of having twice the latency. 回答1: without your description it's hard to be able to suggest the best way to do it. If both servers are inside the same

问题 I am currently having an issue with using a nonce as a security solution in PHP i read this post about How to check if a request if coming from the same server or different server? about using an hidden input form field to hash a random value and At the same time, store that random value into the session that correspond to the user. When the form is submitted, check that the hidden field has the same value as the one that's stored in session. (I think am having a problem with this) Example <?

问题 Smart Wordpress people say that plugin developers should employ a nonce in each AJAX request that is sent from a page back to the wordpress blog (admin-ajax.php). This is done by (1) generating a nonce on the server side, via $nonce = wp_create_nonce ('my-nonce'); ...(2) making that nonce available to Javascript code that sends AJAX requests. For example you could do it like this: function myplg_emit_scriptblock() { $nonce = wp_create_nonce('myplg-nonce'); echo "<script type='text/javascript'
