Encryption and decryption(加密和解密)#说明#使用Key进行加密和解密Key可以是对称的(symmetric)、也可以是非对称的(asymmetric)一般情况下,对称加密的效率高于非对称加密一般情况下,非对称加密的安全性高于对称加密现实情况下,一般使用非对称加密Key,使用对称加密数据,比如:SSL...

Encryption is the process of encoding data into cipher, a form unreadable without a decoding key. Decryption is the reverse process of converting encoded data to its original unencoded form, plaintext. When a user encodes a file, another user cannot decode and read the file without the decryp...
This guide explains encryption & decryption in plain English, with real-world examples & tips. Secure your messages, files, & privacy. ️ Learn everything you need to know, today!
Secure communication using the application of methods like encryption and decryption is the focus of the broader field of cryptography. Encryption specifically uses techniques to convert plain text into cipher text, which requires a key to decrypt. While cryptography covers a wider variety of subjects...
Tryingallpossiblekeysdoesn'thelpyouatall,because all possible plaintexts are equally likely decryptions of the ciphertext. Why are One-Time Pads Perfectly Secure? This result is true regardless of how few bits the key has or how much you know about the structure of the plaintext. ...
Encryption works by sending theoriginal data(or plaintext) through analgorithm(a cipher), which encrypts the data intociphertext. The new text is unreadable unless someone uses the right decryption key to decode it. This is equally true for bothdata at rest(stored someplace, like on a hard...

加密(encryption)是一种获取消息(称为明文 plaintext)并对其实施某个应用操作(称为密码或暗号 cipher)的行为。因此,在收到一条乱码、不可读的消息作为输出时,我们称为密文(ciphertext)。相反的过程,取乱码输出并将其转换回可读的纯文本,称为解密(decryption)。
Triple DES (commonly known as 3DES) is an improvement over the original DES algorithm. Basically, it performs the DES algorithm three consecutive times during encryption and decryption. This makes it far more successful against brute force attacks than the original DES. However, it’s still much...
