BlowFish算法用来加密64Bit长度的字符串。 BlowFish算法使用两个“盒”——ungignedlongpbox[18]和unsignedlongsbox[4,256]。 BlowFish算法中，有一个核心加密函数:BF_En(后文详细介绍）。该函数输入64位信息，运算后，以64位密文的形式输出。用BlowFish算法加密信息，需要两个过程： 1.密钥预处理...
The Blowfish algorithm consists of two major parts: Data encryption.Prior to encryption, 18 subkeys are generated; the same subkeys are used for both encryption and decryption. The P-array and four S-boxes are initialized with the digits of pi. The encryption process consists of 16 rounds an...
The encryption and decryption processes require a set of keys, so the process is called asymmetric cryptography. Some common examples of public-key cryptography in Table 1 include RSA, DSA, Diffie-Hellman algorithm, and Elliptic Curve Cryptosystem (ECC) [31]. Sign in to download hi-res image ...
