加密解密高手进！VB.NET 谁能给一个MD5或其他的加密算法

VB.NET 加密解密算法。能给个现成的。或者给点思路? 加密的原理是什么？

Answer 1

这个是我之前写的。在需要时调用即可。
Public Shared Function Encrypt(ByVal Text As String, ByVal sKey As String) As String
Dim provider As New DESCryptoServiceProvider()
Dim bytes As Byte() = Encoding.[Default].GetBytes(Text)
provider.Key = Encoding.ASCII.GetBytes(FormsAuthentication.HashPasswordForStoringInConfigFile(sKey, "md5").Substring(0, 8))
provider.IV = Encoding.ASCII.GetBytes(FormsAuthentication.HashPasswordForStoringInConfigFile(sKey, "md5").Substring(0, 8))
Dim stream As New MemoryStream()
Dim stream2 As New CryptoStream(stream, provider.CreateEncryptor(), CryptoStreamMode.Write)
stream2.Write(bytes, 0, bytes.Length)
stream2.FlushFinalBlock()
Dim builder As New StringBuilder()
For Each num As Byte In stream.ToArray()
builder.AppendFormat("{0:X2}", num)
Next
Return builder.ToString()
End Function
