vb.net加锁解锁 vb加密解密

IT技术RSACryptoSer

VB.NET开发的软件，大家一般都是怎么加密的网上有很多专业vb.net加锁解锁的加密教程
最适合小开发者vb.net加锁解锁的软件加密方式就是下面这个
获取硬件信息和个人注册时的姓名手机号等一系列信息vb.net加锁解锁 ， 通过预先设定好的加密函数进行散列加密，生成一个只有本人本机能使用的序列号 ， 软件正版授权的时候用同样的方式生成序列号进行比对，一样则通过
VB.NET创建窗体后怎么解除UG选择锁定使用 Explicitily(拼写不一定正确)，就可以正常使用close方法关闭窗体 。只是窗体关闭后，仍然驻留内存中 ， 但是不影响程序的再次启动 。如果是反复调试程序，则必须在UG中手动卸载（文件-实用工具-卸载共享图像，这个“图像”应该是翻译错误 ， 实际上就是程序在内存中的实例） 。
简单VB.NET加密与解密Private Function myEncrypt(ByVal Code As String) As String
Dim Result As String = ""
Dim CurrentChar As Char
For i As Integer = 0 To Code.Length - 1
CurrentChar = Code.Substring(i, 1)
Select Case Code.Substring(i, 1)
Case "Z"
Result = "a"
Case "z"
Result = "A"
Case Else
Result = Chr(Asc(CurrentChar)1)
End Select
Next
Return Result
End Function

vb.net中实现rsa加密解密急！急！我觉得你的并不是RSA加密解密算法 。
在.net的有一个System.Security.Cryptography的命名空间，里面有一RSACryptoServiceProvider的类用来对byte进行RSA加密解密 。
具体例子如下：
using System;
【vb.net加锁解锁 vb加密解密】using System.Security.Cryptography;
using System.Text;
class RSACSPSample
{
static void Main()
{
try
{
//Create a UnicodeEncoder to convert between byte array and string.
UnicodeEncoding ByteConverter = new UnicodeEncoding();
//Create byte arrays to hold original, encrypted, and decrypted data.
byte[] dataToEncrypt = ByteConverter.GetBytes("Data to Encrypt");
byte[] encryptedData;
byte[] decryptedData;
//Create a new instance of RSACryptoServiceProvider to generate
//public and private key data.
RSACryptoServiceProvider RSA = new RSACryptoServiceProvider();
//Pass the data to ENCRYPT, the public key information
//(using RSACryptoServiceProvider.ExportParameters(false),
//and a boolean flag specifying no OAEP padding.
encryptedData = https://www.04ip.com/post/RSAEncrypt(dataToEncrypt,RSA.ExportParameters(false), false);
//Pass the data to DECRYPT, the private key information
//(using RSACryptoServiceProvider.ExportParameters(true),
//and a boolean flag specifying no OAEP padding.
decryptedData = https://www.04ip.com/post/RSADecrypt(encryptedData,RSA.ExportParameters(true), false);
//Display the decrypted plaintext to the console.
Console.WriteLine("Decrypted plaintext: {0}", ByteConverter.GetString(decryptedData));
}
catch(ArgumentNullException)
{
//Catch this exception in case the encryption did
//not succeed.
Console.WriteLine("Encryption failed.");
}
}
static public byte[] RSAEncrypt(byte[] DataToEncrypt, RSAParameters RSAKeyInfo, bool DoOAEPPadding)
{
try
{
//Create a new instance of RSACryptoServiceProvider.
RSACryptoServiceProvider RSA = new RSACryptoServiceProvider();
//Import the RSA Key information. This only needs
//toinclude the public key information.
RSA.ImportParameters(RSAKeyInfo);
//Encrypt the passed byte array and specify OAEP padding.
//OAEP padding is only available on Microsoft Windows XP or
//later.
return RSA.Encrypt(DataToEncrypt, DoOAEPPadding);
}
//Catch and display a CryptographicException
//to the console.
catch(CryptographicException e)
{
Console.WriteLine(e.Message);
return null;
}
}
static public byte[] RSADecrypt(byte[] DataToDecrypt, RSAParameters RSAKeyInfo,bool DoOAEPPadding)
{
try
{
//Create a new instance of RSACryptoServiceProvider.
RSACryptoServiceProvider RSA = new RSACryptoServiceProvider();
//Import the RSA Key information. This needs
//to include the private key information.
RSA.ImportParameters(RSAKeyInfo);
//Decrypt the passed byte array and specify OAEP padding.
//OAEP padding is only available on Microsoft Windows XP or
//later.
return RSA.Decrypt(DataToDecrypt, DoOAEPPadding);
}
//Catch and display a CryptographicException
//to the console.
catch(CryptographicException e)
{
Console.WriteLine(e.ToString());
return null;
}
}
}
[Visual Basic]
Try
'Create a new RSACryptoServiceProvider object.
Dim RSA As New RSACryptoServiceProvider()
'Export the key information to an RSAParameters object.
'Pass false to export the public key information or pass
'true to export public and private key information.
Dim RSAParams As RSAParameters = RSA.ExportParameters(False)
Catch e As CryptographicException
'Catch this exception in case the encryption did
'not succeed.
Console.WriteLine(e.Message)
End Try
[C#]
try
{
//Create a new RSACryptoServiceProvider object.
RSACryptoServiceProvider RSA = new RSACryptoServiceProvider();
//Export the key information to an RSAParameters object.
//Pass false to export the public key information or pass
//true to export public and private key information.
RSAParameters RSAParams = RSA.ExportParameters(false);
}
catch(CryptographicException e)

//Catch this exception in case the encryption did
//not succeed.

vb.net使用如密狗加密狗怎么使用vb.net加锁解锁，分为以下几个步骤 。
1、做加密软件之前先安装好客户端CodeMeterSDK 。打开客户端vb.net加锁解锁，进入CodeMeter功能导航界面 。
2、打开AxProtector自动加密工具 。打开加密工具界面后vb.net加锁解锁，选择您要加密vb.net加锁解锁的程序类型，根据开发者软件vb.net加锁解锁的特点进行选择 。
vb.net怎么用加密狗1、安装加密狗驱动程序vb.net加锁解锁：下载加密狗驱动程序 ， 安装到计算机中 。
2、导入加密狗类库vb.net加锁解锁：在vb.net程序中，导入加密狗类库，可以使用加密狗类库中的API函数 。
3、调用API函数：调用加密狗类库中的API函数，实现与加密狗的交互，实现加密狗的功能 。
vb.net加锁解锁的介绍就聊到这里吧，感谢你花时间阅读本站内容，更多关于vb加密解密、vb.net加锁解锁的信息别忘了在本站进行查找喔 。
