RSA加密解密及RSA签名和验证（转）

技术2022-05-11 26

此Demo包含两个文件，建立一个解决方案，然后建立两个文件，一个为Form，一个为Class，把代码分别复制进去即可RSA正确的执行过程：加密解密：1、获取密钥，这里是产生密钥，实际应用中可以从各种存储介质上读取密钥2、加密3、解密签名和验证：签名：1、获取密钥，这里是产生密钥，实际应用中可以从各种存储介质上读取密钥2、获取待签名的Hash码3、签名其中，1和2的步骤无所谓，在本例中，我们将对txtSource里的内容进行签名，也可以对文件进行签名验证签名：1、获取密钥，这里是产生密钥，实际应用中可以从各种存储介质上读取密钥2、获取待验证签名的Hash码3、获取签名的字串，这里签名的字串存储在m_strEncryptedSignatureData变量中，在DEMO中必须通过签名才能获得这个字串，因此需要先执行签名，当然也可以更改之后通过别的方式获得4、验证其中，1和2的步骤无所谓，在本例中，我们将对txtSource里的内容进行签名验证，也可以对文件进行签名验证如果是文件，取得文件之后把文件的内容以byte[]的方式代入即可/////RSACryption.cs///using System;using System.Text;using System.Security.Cryptography;
