RSA加密解密及RSA签名和验证

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
