利用汇编语言实现DES加密算法-using assembly language to achieve DES encryption algorithm

一款和不错的用VC实现的DES算法,希望对大家对提意见,-section and a good VC with the DES algorithm, we hope that the right to say,

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) -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

DES密码体制的安全性应该不依赖于算法的保密，其安全性仅以加密密钥的保密为基础-DES password security system should not depend on secrecy algorithm, the only security encryption key based on the confidentiality

实现BASE64编码-achieve BASE64 encoding

The Advanced Encryption Standard (AES) specifies a FIPS- approved cryptographic algorithm that can be used to protect electronic data.  The AES-128 pipelined cipher module uses AES algorithm which is a symmetric block cipher to encrypt (encipher) information. This module is optimized for speed as it pipeline hardware to perform repeated sequence called round
