Description: 这学期刚学密码学，RSA算法相对简单，于是写了这个小软件.开发环境:VC++6.0。
RSA的安全性依赖于大数分解。公钥和私钥都是两个大素数。据猜测，从一个密钥和密文推断出明文的难度等同于分解两个大素数的积。
数据加密算法RSA的关键在于大素数的生成,本软件采取数组形式解决大素数的存储和运算问题,可生成超过1024位的十进制数的大素数,以应用于数据加密。
RSA的缺点主要有：产生密钥很麻烦，受到素数产生技术的限制，因而难以做到一次一密。分组长度太大，为保证安全性，n 至少也要 600 bits以上，使运算代价很高，尤其是速度较慢，较对称密码算法慢几个数量级；且随着大数分解技术的发展，这个长度还在增加，不利于数据格式的标准化。
对于明文是字母、数字、符号、汉字的各种组合都能正确加密解密

Description: RSA算法的原理分析及实现。RSA是既能用于数据加密也能用于数字签名的一种非对称密码体制的算法。它有一对密钥，其中之一是私有密钥，由用户保存；另一个为公开密钥，可对外公开。并用VC++语言实现，通过MFC设计的一个小系统来模拟算法的简单应用-RSA algorithm and the realization of the principle. RSA is the best tool for data encryption can be used for digital signatures, a non-symmetric cryptography algorithms. It has a pair of keys, one of which is the private key, by the user preserved another for the public key can be made public. And VC++ Language, through the MFC designed a small system to the simple application of simulation algorithm

Description: (繁体中文版)台湾出品不得多得的关于spa dpa 旁道攻击rsa算法的精彩论文。相对国内的一些翻译性质的、粗制滥造的论文，简直是一个天上一个地下。-As information technology has developed rapidly, it provides more convenient life for people. As the result, the security has become the main concern. Recently, user id and password are major methods to protect private information. However, the short password can be broken by hackers. Too long is not easy to memorize. Network traffic-analyzing tool provides the function to gain the user id and password while doing transaction via network. Therefore, low cost Smart Card including user name identification and cryptosystem algorithm has become new trend of
modern society.
The first object of this thesis is to present the design and implementati- on of a 512-bit RSA cryptosystem by using 8051 microcontroller. In RSA cryptosystem algorithm, modular exponentiation is the essential arithmetic operation. However, 8051 microcontroller does not provide the modular exponentiation. In order to complete RSA cryptosystem, this thesis has mentioned that using L-algorithm to transfer to modular mult

Description: 写了一个文件加解密工具（VC9+OPENSSL）
CA程序：
生成2个RSA密钥对，分别保存为PEM格式，密码保护私钥，文件名为“RSAPrivateKey.pem”和“RSAPublicKey.pem”。
加密：
将指定明文文件加密，密文件格式自已定义，要求文件内容用对称算法（3des）加密，对称密钥（KEY）为随机生成，随机密钥用“RSAPrivateKey.pem”的公钥加密后，存放在密文文件头内（KEY1）；对明文文件做摘要计算（HASH），将计算结果用“RSAPublicKey.pem”的私钥加密后（SIGN），放到密文文件头内；文件头内有明文的原始长度信息。
解密:
将密文文件解密成明文文件，流程与加密相反，先用“RSAPrivateKey.pem”私钥解密（KEY1）数据，得出随机密钥（KEY）；用随机密钥对密文解密，得到明文文件；对明文文件进行摘要计算，得出HASH1；用“RSAPublicKey.pem”公钥解密SIGN，得出HASH2；HASH1与HASH2做对比，相同表示解密成功，不同表示解密失败。
密文文件头内可以保存原始加密人的信息以及解密人的信息，这样可以快速判断解密者是否有权限解密该密文文件，如果有权限则进行解密过程，否则直接提示没有权限解密。
-To write a file encryption and decryption tool (VC9+ OPENSSL)
CA procedures:
Generates two RSA key pairs, respectively, save for the PEM format, password-protected private key, the file named "RSAPrivateKey.pem" and "RSAPublicKey.pem".
Encryption:
The specified plaintext file encryption, secret self-definition file formats require the document to use symmetric algorithms (3des) encryption, symmetric key (KEY) is randomly generated, random key to use "RSAPrivateKey.pem" public key encryption, stored in the ciphertext header inside (KEY1) summary of the calculation of the plaintext file to do (HASH), the calculation results with the "RSAPublicKey.pem" private key encryption (SIGN), into ciphertext in the file header file header if there is express The original length of the message.
Decryption:
Decrypt the ciphertext into a plaintext file documents, processes and encrypt the contrary, the first to use "RSAPrivateKey.pem" decrypt the private key (KEY1) data, derived random k
