Description: des算法简单实现。它以64位的明文和56位的密钥作为输入，通过DES加密运算产生64位密文输出。其解密过程利用同以密钥和算法将密文还原成明文。因为java语言的安全性＆网络处理能力强，所以就利用了java语言编写-des simple algorithm to achieve. It's expressly 64 and 56 as the key input, through DES encryption algorithms have 64 ciphertext output. Its use decryption process with a key and cipher algorithm reduced explicitly.

Description: JAVA中的Blowfish加密属于对称密钥算法，如果知道密钥，则可以对加密后的数据解密，但如果如果不知道密钥，基本上是不可能的，因此，这就决定了它的先天不足，就是带来的密钥的管理问题。-JAVA The Blowfish symmetric key encryption algorithms are, if you know the key, you can decrypt the encrypted data, but if if you do not know the key, it is basically impossible, therefore, which determines its defects, is brought about key management issues.

Description: 本篇内容简要介绍BASE64、MD5、SHA、HMAC几种加密算法。
BASE64编码算法不算是真正的加密算法。
MD5、SHA、HMAC这三种加密算法，可谓是非可逆加密，就是不可解密的加密方法，我们称之为单向加密算法。我们通常只把他们作为加密的基础。单纯的以上三种的加密并不可靠。 -This brief introduction to the contents of BASE64, MD5, SHA, HMAC several encryption algorithms. BASE64 encoding algorithm is not a real encryption algorithm. MD5, SHA, HMAC three encryption algorithms can be described as non-reversible encryption and decryption of the encryption method is not, we call one-way encryption algorithm. We usually put them as the basis for encryption. These three simple encryption is not reliable. Platform: |
