非常简单却实用的一款通讯簿,主要特色是支持密码保护功能,可以实现联系人信息的保密.-very simple but practical one Address Book, the main feature is support password protection function, Contact information can achieve confidentiality.

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 with 512-bit packet to process the input information, and each group was again divided into 16 32-seat group, after a series of processing, the algorithm" s output consists of four 32-bit group composed of these four 32-bit Cascade Group will generate a 128-bit hash value.
