    Base64 demonstrates how easy it is to decipher plaintext usernames and passwords. Never login to a public network resource unless some type of encryption is being used, secure socket layer is one example. Most FTP sites also use plaintext passwords.

    RC5-CTS模式加密解密算法C++程序实现。 解压之后运行main.dsw.在VC++下面打开,执行之后根据显示首先输入密钥(随便输入不超过16字节的字符串),之后提示输入需要加密的plaintext文件,输入plaintext1.txt,这个文件在压缩包里已经存在,(注意一定要写清楚文件类型名,是个文本文件),然后根据提示输入加密文件名,可随便输入一个文件名,但是别忘记了类型名.txt,如ciphertext1.txt。因为不输入类型名将来无法打开。之后输入解密之后的文件名,可输入decrypted.txt 结束。 之后打开生成的ciphertext1.txt和decrypted.txt,还有原来的明文文件plaintext1.txt,可以看出decrypted.txt和plaintext1.txt内容一致。ciphertext1.txt由plaintext1.txt加密得到,而decrypted.txt由ciphertext1.txt解密得到

    Program for implementing AES on 8051 based microcontrollers. SDCC is used as the C compiler. Microcontroller used is P89V51RD2. There are 2 programs included. One program will accept string via UART and accept key via a 4x4 keypad and display decrypted text on 16x2 LCD. The other program will accept plaintext from UART and show encrypted text on 16x2 LCD after receiving key from 4x4 membrane keypad. Schematics and screenshots are included.

  • Playfair Cipher 1.not even the large number of keys in a monoalphabetic cipher provides security 2

    Playfair Cipher 1.not even the large number of keys in a monoalphabetic cipher provides security 2.one approach to improving security was to encrypt multiple letters 3.the Playfair Cipher is an example 4.invented by Charles Wheatstone in 1854,but named after his friend Baron Playfair Playfair Key Matrix 1.a 5X5 matrix of letters based on a keyword 2.fill in letters of keyword (sans duplicates) 3.fill rest of matrix with other letters Encrypting and Decrypting -plaintext is encrypted two letters at a time 1. if a pair is a repeated letter, insert filler like X’ 2. if both letters fall in the same row, replace each with letter to right (wrapping back to start from end) 3. if both letters fall in the same column, replace each with the letter below it (again wrapping to top from bottom) 4. otherwise each letter is replaced by the letter in the same row and in the column of the other letter of the pair
