Often there is the need to generate promotional posters, including the specified QR code, to share someone else to scan the code to determine the user referral relationship.Careful analysis, the necessary elements of the promotion poster is the poster background and QR code, both of which are easy to generate, but to combine the two together into a picture two-dimensional and can be saved to the local easy

APT (Annotation processing Tool) can parse annotations at code compile time and generate new Java files, reducing manual code input. Now there are many mainstream libraries are used APT, such as Dagger2, Butterknife, EVENTBUS3, and so on, we have to keep up with the trend of the Times na! (ง ̀_ ́) ง The following is a simple View injection project viewfinder to introduce APT related content, simple implementation is similar to butterknife two kinds o

Generate an AWR report for a specific DB instance in the RAC environment:@ $ORACLE _home/rdbms/admin/awrrpti.sql4. How to generate AWR reports for multiple DB in

SSL security certificates can be generated on their own or through a third-party CA (certification authority) Certification Center payment request. SSL security certificates include: 1, CA certificate, also called root certificate or intermediate level certificate. For one-way authenticated HTTPS, the CA certificate is optional. The primary purpose is to make the certificate a chain of certificates to achieve the purpose of the browser trusting the certificate. If a CA certificate is used, both

Rand_max is defined in

First, create a new validate ASPX validation page. Then generate the Captcha control ImageButton, and then generate the picture form.The code is as follows:Using System;Using System.Collections;Using System.Configuration;Using System.Data;Using System.Linq;Using System.Web;Using System.Web.Security;Using System.Web.UI;Using System.Web.UI.HtmlControls;Using System.Web.UI.WebControls;Using System.Web.UI.WebCo

Original introduction of OpenSSL OpenSSL is currently the most popular SSL password library tool, it provides a universal, robust, full-featured tool suite to support the implementation of the SSL/TLS protocol.Official website: https://www.openssl.org/source/ composing partial cipher algorithm library key and certificate encapsulation management function SSL Communication API Interface use establish RSA, DH, DSA key parameters to establish X.509 Certificates, certificate signing requests (CSRs

Create a Test Catalog mkdir/tmp/create_key/cacd/tmp/create_key/ certificate file Generation : One. Server-side 1. Generate the server-side private key (key file): OpenSSL genrsa-des3-out Server.key 1024 The runtime prompts for a password, which is used to encrypt the key file (the parameter des3 is an encryption algorithm or other secure algorithm), and every time a password is required to read the file (via the command or API provided by OpenSSL), t

on how to install the VS2013 and MSDN, there are many tutorials on the web, again not to repeat, I believe that everyone has been installed. This MFC programming entire process uses the Simplified Chinese specialized edition VS2013 to carry on the operation. This gives you a simple example of how to generate a single document application framework. Solutions and Engineering The concept of solution and engineering has been discussed in the introduction

Label:Testing is an important part of the project, and in Visual Studio 2010, it has been well supported in testing, such as unit testing, load testing, and so on. In the area of data testing, Visual Studio 2010 also supports a variety of tests on the database, one of the most useful features is the ability for developers in the testing phase, a lot of convenient to generate random data for the database, but also can specify the rules for generating d

Two ways to generate keys in LinuxThe SSH service supports a security authentication mechanism, that is, key authentication. The so-called key authentication, is actually using a pair of cryptographic strings, a public key (PublicKey), anyone can see its content for encryption, and the other is called the key (Privatekey), only the owner can see, for decryption. Ciphertext encrypted with a public key can be easily decrypted using a key, but it is diff

At present, the machine identification verification code has been quite powerful, more common to avoid the machine recognition method, is to connect the verification code string together, so that the difficulty of recognition, after all, the machine does not have artificial intelligence. I looked for a lot of. NET Generate picture Verification code example, later after some modification and collation, almost satisfied my requirements: The picture has

How to generate random numbers in C/s + +: The rand () function, the Srand () function, and the random (int number) function in the C language/c++ are used here.(1) If you just want to generate random numbers without setting the range, you just have to use rand () to be able to: rand () will return a random number, ranging from 0 to Rand_max. Rand_max is defined in stdlib.h with a value of 2147483647.Like w
