RSA generator and Digital Signature
RSA Generator and Digital Signature Author: Jian Li (ID:yinyanghu), an undergraduate student in Nanjing University, China E-mail: [email protected] Google Talk: [email protected] ****************************************************************************************************************************** 我做的Task是RSA Public Key系统,并且利用生成的RSA密钥做了一个Digital Signature 我是在Linux下coding的,所以下面的命令都是unix命令,如果您是在Windows下运行,利用命令行终端进入Bin目录,然后运行exe文件即可 RSA.cpp RSA Public Key Generator 用来生成RSA密钥,有四种Mode (0) (Default)Demo 生成一个250位左右的RSA Key,用作演示 (1) --high-performance 生成一个500位左右的RSA Key,在对性能有较高要求及安全性较低要求时使用 (2) --high-reliability 生成一个750位左右的RSA Key,在对安全性有较高要求时使用,大概能在5 Minutes内出解 (3) --prime 随机生成一个指定位数的大质数,基于Miller-Rabin Algorithm (4) --digital-signature 生成两套RSA密钥,用于后面的Digital Signature程序 屏幕上输出的Trial,是在生成一个大质数时,产生随机数的个数 Example: unix > ./RSA --high-performance 输出三个文件,默认为RSA_Key, RSA_Public_Key, RSA_Private_Key,其中RSA_Key为生成的RSA密钥的信息,另外两个文件为 Digital Signature 程序所需 也可以在运行时,指定输出文件名 Example: unix > ./RSA --high-performance AKS or unix > ./RSA MST 则输出文件分别为: AKS_RSA_Key, AKS_RSA_Public_Key, AKS_RSA_Private_Key or MST_RSA_Key, MST_RSA_Public_Key, MST_RSA_Private_Key 如果是 --digital-signature Mode, 则输出被指定为 Alice_RSA_Key, Alice_RSA_Public_Key, Alice_RSA_Private_Key and Bob_RSA_Key, Bob_RSA_Public_Key, Bob_RSA_Private_Key 如需帮助,请输入 --help Example: unix > ./RSA --help Encoder.cpp Digital Signature Encoder 利用RSA产生的密钥,来加密自己的Signature,并转化成Digital Signature **************************************************************************************** Attention! 在运行本程序前,请务必运行RSA程序的--digital-signature Mode **************************************************************************************** 程序默认利用RSA程序 --digital-signature Mode下生成的两套密码,即默认密钥输入是来自文件 Alice_RSA_Key, Alice_RSA_Public_Key, Alice_RSA_Private_Key and Bob_RSA_Key, Bob_RSA_Public_Key, Bob_RSA_Private_Key 的,若要从其他文件中读入密钥,则使用参数 --name Example: unix > ./Encoder --name 程序会把你输入的签名,加密后,写入文件Signature 请将此文件和你的Public Key发给Receiver 如需帮助,请输入 --help Example: unix > ./Encoder --help Decoder.cpp Digital Signature Decoder 利用RSA产生的密钥,来解密自己的Signature,并转化成Digital Signature **************************************************************************************** Attention! 在运行本程序前,请务必运行Encoder程序 **************************************************************************************** 程序默认利用RSA程序 --digital-signature Mode下生成的两套密码,即默认密钥输入是来自文件 Signature, Alice_RSA_Key, Alice_RSA_Public_Key, Alice_RSA_Private_Key and Bob_RSA_Key, Bob_RSA_Public_Key, Bob_RSA_Private_Key 的,若要从其他文件中读入密钥,则使用参数 --name Example: unix > ./Decoder --name 程序会把Sender发送的Signature文件中的签名,解密后,输出到屏幕上 如需帮助,请输入 --help Example: unix > ./Decoder --help Digital Signature完整运行过程: unix > ./RSA --digital-signature unix > ./Encoder unix > ./Decoder Copyright © 2011 Jian Li.
