RSA加长分段解密算法，界面操作。算法步骤如下：1. 读取私钥d和n，作解密之用。 2. 从EncText中读取一大段密文，再把该大段密文分成若干小段密文。 3. 使用d和n把所有小段密文进行解密成对应的小段密文sectBYTE[]，再合成一大段明文字节数组BYTE[]，并转化成大段明文添加到DecText。 4. 读取下一大段密文，若密文为空，完成解密；否则转2

A collection of math routines including 8-bit, 16-bit, 32-bit signed and unsigned addition, subtraction, multiplication, and division. Very nice code library with heavy in-line documentation! Been looking for multi-BYTE divide? Here it is.

用C51实现的拼音输入法,这是改写的网友 embuffalo、独步上载在www.21ic.com自由发布区的由张凯原作的51上的拼音输入法程序。 原作使用了一个二维数组用以查表，我认为这样比较的浪费空间，而且每个字表的索引地址要手工输入，效率不高。所以我用结构体将其改写了一下。就是大家现在看到的这个。 因为代码比较的大，共有6,000多汉字，这样就得要12,000 BYTE来存放GB内码，所以也是没办法的 :-( 编译结果约为3000h,因为大部分是索引表，代码优化几乎无效。 在Keil C里仿真芯片选用的是华邦的W77E58，它有32k ROM, 256B on-chip RAM, 1K on-chip SRAM (用DPTR1指针寻址,相当于有1K的片上xdata)。条件有限，没有上片试验，仿真而已。 打算将其移植到AVR上，但CodeAVRC与IAR EC++在结构体、指针的定义使用上似乎与C51不太一样，现在还未搞定。还希望在这方面有经验的网友能给予指导。

可以将以bit为单位进行处理的算法扩展到8位，即以BYTE为单位进行处理。由于有8个bit，所以有2^8种选择。这样明显会使运行时 间大为减少，速度明显更快，但是也有它的缺点，即，占用资源太大，所以综合考虑速度和 资源两点，采用半字节查表法。即以半 BYTE为单位进行处理。由于有4个bit，所以有2^4种选择。

This example shows how to transmit and receive packets with packet length up to 255 BYTEs. The status BYTE is polled every 200 us in a timer1 int.

This a two node test, requires a Coordinator and an RFD. The coordinator and node simply ping-pong a packet back and forth, and print out the RSSI BYTE. The RFD waits before bouncing it back, while the coordinator responds immediately.

This unit uses an array of BYTEs to represent a LARGE number. The number is binairy-stored in the array, with the Least Significant BYTE (LSB) first and the Most Significant BYTE (MSB) last, like all Intel-integer types.

What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used(In VB - The same technique can be implemented in "c" also.) Program flow Explained * Open the File to be encrypted for Binary Access Read(Say Source File) * Open a temparory file where encrypted data is stored for Binary Access Write(Say Destination File) * Loop through the Source File BYTE by BYTE * For each BYTE read from the file, Complement the data. (Using Not operator (in C we have to use "~" operator) * Write Complemented Data to Destination File * Delete the Source File * Rename Destination file as Source File(Now Encryption is over)
