字符解密
- 这是一个通过字符串操作来实现文本加密解密的源程序,通过打乱原文本字符串的顺序,隐藏信息,通过解密,可以回复原字符正常顺序,达到加密解密的目的.压缩包包括源程序文件,再vc中运行.-This is a string manipulation through the text to achieve encryption and decryption of the source, through the disruption of the text string in the order, hide
HuffmanCode
- 对文本信息进行哈夫曼加密，并将哈夫曼树及密码保存，然后进行解密。-Huffman text information encryption, and password and Huffman tree preservation, and then decrypt.
shamir
- This program makes some operations on the polynomials, such as addition, multiplication and calculating Lagrange polynomials. It also finds a key for encryption of a text and then does encryption process by using xor (exclusive-OR) of each character
JavaApplication2
- Java Shannon Fano Algorithm , encryption and decryption. CitireBit.java read bit by bit from text/bmp file Compara.java compares 2 bits In.txt it s the in file for the interface and algorithm Interfata.java it s the interface file Nod.java
Binary-text-digital-image
- 提出了一种可抗 几何攻击的二值文本图像水印算法. 该算法基于DCT,它将二值图像的DCT、图像的视觉特征向 量和加密技术有机结合起来,在提取水印时不需要原始图像,是一种实用的盲水印算法-We propose a geometric attacks against Binary Text Watermarking Algorithm. The algorithm is based on DCT, it binary image DCT, the image of the visual fe
transposition_enc
- To find the transposition encryption in a text.
simple_crypt
- A very simple encryption program able to encrypt a text according to a password. Result is stored in a local text file. Then you can decrypt the message if you use the same password.
Huffman100
- 使用Huffman编码进行文本加密（压缩）的一个示例程序。输入一段文字，自动建立Huffman树并生成各字符对应编码，并对编码前和编码后分别占用的空间进行计算-A sample program using Huffman code for text encryption (compression). Enter a text, program will automatically create Huffman tree and generate the corresponding charact
WordCount
