采用MD4哈希函数的随机数生成函数，已在ARM环境下测试过。可应用于如无线数据发送时的随机避让。-Random number generator utilizing MD4 hash function of environmental noise captured as the seed and a linear congruence generator for the random numbers.

超精简的c语言malloc内存管理函数，采用哈希散列法+伙伴法结合，自动判断切割或合并，已在linux上测试，并在一web服务器上实现商业化应用-minimalloc by c .tested in linux and iar ，has been used in WEB server

通过单片机实现哈希函数SHA-1，C源程序完全可用，已经测试，外部加密芯片采用DS28E01-1-MCU hash function SHA-1, C source code fully available, and has been tested external encryption chip uses DS28E01-100
