Symmetric key encryption in HTTPS, public key encryption, digital certificate keyWe call unencrypted content plaintext, and the encrypted content is called ciphertext.In short, to encrypt a piece of plaintext, you can enter this content into an encryption function, output ci

Des:Digital Encryption Standard. Obsolete Standard.Single key algorithm is the sender of the information using key A for data encryption, the receiver of the information uses the same key a for data decryption. The single key algo

Reprint: http://blog.csdn.net/a1232345/article/details/44594867 explanation of public key and private key公钥: For outward release, accessible to anyone,私钥: To save yourself, do not give othersThe two situations are often confused and must be understood.Case 1: Public key for "encryption", private

The principle is to set a dark key. Condition: original text, plaintext key, dark key count nEncryption process:1. A Random N-bit integer is generated as the dark key.2. Combine the plaintext key and the hidden key to design an

to describe the current state of a device. These features include: orientation of the screen, screen density, screen size, keyboard type, docking mode, language, and so on. Imagine a small pop-up window that partially obscures the current activity interface. When it appears, the masked activity is suspended by the system (OnPause ()) and the user cannot interact with it. When the small pop-up window is closed, the masked activity will start to run again. Click the Android device back

Asymmetric encryption has been rated as the encryption standard, mainly includes (public key encryption private key decryption, or private key encryption public

Recently, because the project needs to use RSA encryption to ensure that the client and server communication security. But C # 's own RSA algorithm class RSACryptoServiceProvider only supports public key cryptographic private key decryption, that is, the use of digital certificates. So reference some of the information on the Internet to write a RSA algorithm im
