cryptography for kids

Welfare of kids shoes-GitHub Chinese INS, kids shoes-github I am very excited to see a plug-in a front-end group today! I will share the steps for implementing the plug-in! After the plug-in layout is complete, it will inevitably be a little excited! I removed the chrome plug-in Tampermonkey_v4.0.25.crx and added the new script to main. js. It is also finished. I feel no difference! If the plug-in downloade

How does cryptography protect block chains ?, Cryptography is a protected area Cryptography is a science that Applies mathematical functions to ensure data security. Many popular movies and TV works imply that any system can be cracked if there are enough hackers. This "Hollywood hacker attack" is not a real-world scenario-hackers must discover system vulnerabili

Finding discrete logarithms is very difficultRSA is the first letter of the surname of Ron Rivest/adi Shamir/leonard Adleman.RSA can be used for public key cryptography and digital signatures.RSA encryption: Ciphertext = plaintext EMODN (e and N are public keys)RSA decryption: plaintext = ciphertext DMODN (d and n are private keys)The decryption of RSA:Brute force: The difficulty of brute force will increase with the length of D, and when D is long en

Both A and B were on two islands. B is sick, and a has the medicine that B needs. C has a boat and a lockable box.C is willing to carry things between A and B, but things can only be placed in boxes. As long as the box is unlocked, C will steal everything from the box,No matter what's in the box. If A and B each have a lock and can only open the key of their own lock, how should a be delivered to B?Answer: A put the medicine in the box, lock the box with your own locks. b After getting the box,

Today Learning elliptic curve cipher (Elliptic Curve CRYPTOGRAPHY,ECC) algorithm, his hand lacks the introduction of the algorithm of professional books, so on the internet to check a lot of blog and books, but most of the blog writing is really ... You know... Really deserves to be ' the world article a big copy ' Ah! The same does not say, the key is the introduction is not very clear, is I in the process of reading, produced a lot of doubts can not

The current password must be tested by countless people, proving that there is no trap. If you are not public, no one believes in the security of your algorithm.Many algorithms are later proven to be unsafe. Simply put, the three main foundations of modern cryptography are:1, the introduction of large prime numbers;3, the irreversible nature of the algorithm;2, based on computer operation rather than hand calculation.Based on these three points, in

The basis of probability theory Suppose X and y are random variables defined on a finite set of x and Y respectively. Joint probability P (xi,yi) p (x_i,y_i) is the probability of X=xi,y=yi x=x_i and y=y_i. Conditional probability P (xi|yi) p (x_i \vert y_i) is the probability of Y=yi y=y_i when X=xi x=x_i. If there are P (x,y) =p (x) p (Y) p (x, y) = P (x) p (y) in any x∈x,y∈y x \in x, y \in y, then the random variable x and y are statistically independent. Bayes theorem: P (x| Y) =p (X) P (y

Introduction to the kids log system As the business and system scale grows, the number of machines in Our backend is also increasing, bringing about many new problems, such as unified system release and upgrade, monitoring, and so on. We believe that everyone has their own ideas and practices for solving these problems. This blog post does not intend to expand on these problems, but starts from one of the points-logs. No matter how a system is impleme

In the recently leaked Windows 8.1 build 9369, another netizen has discovered a new feature-"Kids Corner", which users familiar with Windows Phone 8 should not be unfamiliar with. Kids Corner The user found a "Kids Corner" icon in the Imageres.dll file of Windows 8.1 build 9369, a function that assists parents in managing their children's use of the comp
