我们紧接着上篇,这篇将介绍如何使用Cryptography WinRT API,来实现
加解密.
本篇将介绍如下9个方面:
a)CryptographicBuffer类来转换和编码字符串
b)HashAlgorithmProvider 类 支持哈希算法
c)MacAlgorithmProvider 类 支持HMAC算法
d)KeyDerivationAlgorithmProvider类 支持对称算法
e)SymmetricKeyAlgorithmProvider类 支持对称算法
f)EncryptedAndAuthenticatedData类 支持认证加密算法
g)AsymmetricKeyAlgorithmProvider类 支持非对称算法
h)AsymmetricKeyAlgorithmProvider类 支持签名算法
i)DataProtectionProvider类
我们的创建的步骤如下:
1)为了组织文件方便,我们先建一个文件夹CryptoWinRT
2)向文件夹中添加如下文件:
CryptographicBufferTest.xaml,HashAlgorithms.xaml,
HmacAlgorithms.xaml,KeyDerivation.xaml,
CipherAlgorithms.xaml,AuthenticatedEncryptionAlgorithms.xaml,
EncryptAndDecrypt.xaml,SignAndVerifySignature.xaml,
AsynchronousDataProtection.xaml,AsynchronousDataProtectionWithStreams.xaml,
创建方法请参照前一篇.
3)此时的解决方案结构如下:
4)向我们的DataSource添加导航所需要的信息
修改我们的SampleDataSource.cs文件中的SampleDataSource类中的代码,
代码如下:
