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
