cryptography

Thought of by the TV series "Dark computing"-mathematical principles of cryptography I watched the TV series "Dark computing" a while ago and liked its ideas and performances. One story mentions cryptography. the story itself is good, but it is a

I,Public KeyEncryptionAssume that I have two numbers: 1 and 2. I like the number 2 and keep it. I won't tell you (Private Key), and I will tell you that 1 is my public key. I have a file that cannot be viewed by others. I use 1 for

What is private key cryptography technologyThe private key (symmetric key), also known as the symmetric key. The key encryption algorithm uses the same key for encryption and decryption. It has the advantage of very fast encryption and decryption,

This article is a basic article on Software encryption technology. It briefly introduces some basic knowledge about Software Encryption and some encryption products. It is suitable for domestic software developers or individual software developers

  The enterprise database encryption application module provides two methods for users to protect their data: Hashingproviders:In short, the discrete encryption method saves your information to the memory and uses a discrete value to represent it

Said the front of those, think of a thing, this series based on the content mainly from the "Modern Cryptography" Ma Chunguang authoring. I am the one who studies this book.Well, the classical password is the ancient code, haha, tease you to play,

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

Recently in Research cryptography cryptography, signature aspects of things. After a few days of learning to some basic knowledge of the finishingPKI:PKI is the acronym for Public Key Infrastructure, which translates to the PKI, which is the

Java Encryption and Decryption basicsCryptography is a technological science that studies the coding and decoding of passwords. This paper studies the objective Law of password change, which is used to compile passwords to keep the secret of

The biggest disadvantage of the symmetric password is that the key management is difficult, because the two sides of the communication must reserve the same key after the encryption, and in the network environment, the key should be replaced
