Turn from: HTTPS Unidirectional authentication Instructions _ digital certificate, digital signature, SSL (TLS), SASLBecause TLS + SASL is used in the project to do the security authentication layer. So read some online information, here to do a summary.1. First recommend several articles:Digital certificate: http://www.cnblogs.com/hyddd/archive/2009/01/07/1371292.htmlDigital certificates and ssl:http://www

Digital Certificate and its authentication process [reprinted], digital certificate reprinted As we all know, public key cryptography makes it easy to use digital signatures, encrypted communications, and other key services by using the public key and private key pair. The reason why public key technology can be widely used is that for entities that use the publi

would tell that the message really came from someone with a private key. The process of encrypting private keys is a digital signature.Data encrypted with the public key can only be decrypted by the private key, whereas the data encrypted with the private key can only be decrypted by the public key, and it is this asymmetry that makes the public-key cipher system widely used.2.2. AdvantagesCompared with symmetric key encryption, the advantage is that

enough. MD5 (RFC 1321) is an improved version of Rivest in 1991 for MD4. It still groups the input in 512 bits, and its output is 128 bits. MD5 is more complex than MD4, and is slower to calculate, but more secure. MD5 is not safe enough. SHA1 (Secure Hash algorithm) is designed by the NIST NSA, whose output is a Hash value of 160 bits in length, so it is better for anti-poor lifting. The SHA-1 design is based on the same principles as MD4 and mimics the algorithm. To improve security, the NIST

Search for "What

Digital Image) An image can be defined as a two-dimensional function f (x, y). Here, X and Y are spatial coordinates, and in any coordinate (x, y) the amplitude F is called the brightness or gray scale of the image at the coordinate position. When the amplitude of X, Y, and F are finite discrete values, they are called digital images. Note that a digital image

This article mainly introduces the digital verification code and the digital operation Verification Code implemented by php. It describes the related techniques for php to implement the digital verification code and the mathematical operation verification code in the form of examples, which is very simple and practical, for more information, see This article main

Bob has two keys, one is the public key, the other is the private key. 2. Bob gave his public key to his friends----patty, Doug, Susan----each one. 3. Susan is going to write a confidential letter to Bob. When she finished, she used Bob's public key to encrypt it, and it was a secret effect. 4. When Bob

Blockchain Enthusiast (qq:53016353) The goal of this developer's Guide is to provide you with enough information when you develop a digital currency peripheral application. In order to better use this guide, you need to install the latest Bitcoin kernel client, you can download the source code in GitHub or the pre-compiled version of the official website. Once the installation is complete, you will have the following three executables: Bitcoind, BITC

The basic definition and nature of digital root can be found in the reference to Wikipedia.First, the definitionThe digital root is the addition of a number of numbers, plus the number of the numbers, until the number is one digit. And this one number is the digital root of the original number. The applicable range is positive integers and 0. For example: 65536,6

control functions, memory and disk for storing data, keyboard, mouse and monitor are used to connect the operators. First, the computer is a digital processor; second, the computer uses BITS to represent information; again, the larger information is represented by a bit group. And everything is a binary number 0 and a representation ... It's all a bit like magic and fun.Then introduced the cpu--CPU, RAM random access to memory (the CPU can quickly ac

PHP Digital Verification Code, PHP digital Verification Code It is very convenient to implement verification code in PHP, the key point is to master the use of PHP GD Library and session. Throughout the online PHP generation Verification code example, is not all PHP GD library and session combination, and the use of PHP generated random number method to complete. PHP Verification code, can be divided into

Digital baseband signal a digital baseband signal is a waveform that represents digital information, which can be expressed in different levels or pulses. There are many types of digital baseband signals. This paper introduces several basic baseband signal waveforms with rectangular pulses as an

The Government of "Moderdesh" is planning to enter the digital age and so people of different professionAnd business is proposing different ways to enter this age successfully. The hardware vendors isSaying that we need to provide a laptop for each student, the mobile companies is saying that everyChildren needs to has a mobile phone in he small hand and talk all night long, the multimedia expertsIs crying for multimedia University and so on. But very

Encryption and decryption use the same key algorithm, called symmetric encryption algorithm. encryption and decryption use different keys, called asymmetric encryption algorithms. The public key system is an asymmetric encryption algorithm. For symmetric encryption, symmetric keys must be protected. For public key algorithms, private keys must be protected.Public key encryption algorithms and derived digital signatures and

[Opencv] pixel-operated digital image processing and opencv Digital Image Processing A few days ago, the matlab was used to process digital images and matrix operations. If you forget linear algebra, it would actually be GG. After using matlab, I decided to use opencv. C ++ seems to be a good tool for processing digital
