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...
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 decryption key. Adding a digital signature, a form of personal...

An encryption algorithm is the method used to transform data into ciphertext. An algorithm will use the encryption key in order to alter the data in a predictable way, so that even though the encrypted data will appear random, it can be turned back into plaintext by using the decryption ke...
For those without a decryption key, encrypted messages are virtually impossible to decipher. However, users with the decryption key can successfully decrypt the data, essentially reversing the encryption process and converting the ciphertext back into unencrypted, readable plain text. ...
Figure 36-12CBC Mode Encryption and Decryption In CBC mode, because plaintexts are scrambled before encryption, the ciphertext pattern never appears in the final result. So we cannot see the "AES" letters inFigure 36-13as we could inFigure 36-11. ...
