生成大素数并检验以及生成RSA1024位公钥子程序，不使用库文件，源代码公开，清晰有注释-Generate large prime numbers and testing, and to generate RSA1024-bit public key subroutine, do not use library files, source code is open, clear and annotated

IDEA加密算法属于数据块加密算法(Block Cipher)类。IDEA使用长度为128bit的密钥，数据块大小为64bit。-IDEA encryption algorithm is data block encryption algorithm (Cipher Block) category. IDEA use of the length of the 128 bit key, the data block size for 64bit.

MD5算法的实现。MD5以512位分组来处理输入的信息，且每一分组又被划分为16个32位子分组，经过了一系列的处理后，算法的输出由四个32位分组组成，将这四个32位分组级联后将生成一个128位散列值。 -MD5 algorithm. MD5 to 512 groups to deal with the importation of information and each group was also divided into 16 groups of 32 seats, After a series of processing, the output from the algorithm 4 32 subgroups, 4 32 this group will generate a cascade 128 hash value.
