实现加密字符串技术，程序根据概率统计自动绘制一张加密表，然后对输入字符串进行加密和自动解密工作，不过为了节省时间，只能对小写字母进行加密-Technology to achieve the encrypted string, the program automatically based on probability and statistics to draw an encrypted form, and then the input string to encrypt and decrypt

本人修改的成熟的霍夫曼编码及译码，对一个文本文件，统计字符概率，建霍夫曼树，然后编码，最后译码，码文输出到另一份txt文档中，在vc中编译的，在vs2010中可能会有异常~-I modified Huffman coding and decoding of the mature, to a text file, statistics, probability character, Huffman tree construction, and coding, and finally decodin

古典密码，通过概率统计判断加密算法是单表替代或是多表替代并初步估计是由几重替代-Classical cryptography, encryption algorithms via probabilistic judgment is replaced or a single table and multi-table alternative initial estimate is replaced by a few heavy
