;$numChars = count ($chars)-1;$token = ';# Create Random token at the specified lengthfor ($i = 0; $i $token. = $chars [Mt_rand (0, $numChars)];# Should token be run through MD5?if ($MD 5) {# Number of char chunks$chunks = Ceil (strlen ($token)/32);$MD 5token = ';# Run each

Label:Because the server side restricts the call API to get the data interface, we need to get a access-token before calling the API, so we need to implement this Access-token function in iOS. The server side is the use of the client Credentials Grand Way to issue tokens in ASP. Owin OAuth based on the implementation details of this blog.

Token, the most important feature of tokens, is randomness, unpredictable. General hackers or software can not guess out.So, what does token do? What is the principle of it?Tokens are typically used in two places- preventing forms from repeating commits, anti CSRF attacks (cross-site request forgery). Both are based on the principle of the session token to achiev

image of all the available image digest, the link file inside the image of the digest. We go to blobs inside to find the corresponding ID corresponding to the file, view the file below the data, we found that the data file stored in the information, and we registry through the V2 REST API request manifest information is the same ~ in See _manifest/tags/. Here is a different tag for this image. It also points out that current and index represent the digest and all Mirror Digest under this tag, r

space, so the number of cookies per domain is limited.The composition of a cookie consists of a name (key), a value, a valid domain (domain), a path (the path of a field that is generally set to global: "\"), an expiration time, and a security flag (when specified, the cookie is sent to the server (HTTPS) only when the SSL connection is used). Here is a simple example of JS using cookies:A cookie is generated when a user logs on:Document.cookie = "id=" +result.data[' id ']+ "; path=/";Document.

PHP prevents duplicate submission of forms2016-11-08 Easy to learn PHPOne of the limitations we cannot ignore when we submit a form is to prevent users from repeating the form, because it is possible for users to repeatedly click the Submit button or the attacker to maliciously commit the data, so we will be in trouble when we post the data, such as modifying or adding data to the database.So how to avoid the recurrence of this form of the occurrence of the phenomenon? We can start with a lot of

The humble article uses the JMeter to test the Beijing PK10 platform Production (www.1159880099.com) QQ1159880099 with the CSRF token authentication Web API; In recent days, the project was not busy and practiced coding.With the foundation of the previous JMeter script, basically the difficulty is in two places: Get the CSRF token, the transfer of the cookie.Add dependencies First, and add the following in

Recently understand the Token based authentication, share with everyone. Many large web sites are also used, such as Facebook,twitter,google+,github, and so on, compared to the traditional authentication methods, Token scalability is more powerful, and more secure, very suitable for use in WEB applications or mobile applications. Token in Chinese translated into
