C# 在c语言中强行将字符放入文本框#
我想做一个“测试密码”的程序，看看用基本的暴力攻击破解密码需要多长时间。所以我做了两个文本框。 （C# 在c语言中强行将字符放入文本框#,c#,algorithm,textbox,passwords,brute-force,C#,Algorithm,Textbox,Passwords,Brute Force,我想做一个“测试密码”的程序，看看用基本的暴力攻击破解密码需要多长时间。所以我做了两个文本框。 （textbox1和textbox2）并编写了程序，因此如果文本框有输入，将出现“正确密码”标签，但我想编写程序，以便textbox2将在其中运行暴力算法，当遇到正确密码时，它将停止。我真的需要帮助，若你们能在我的附加代码中加入正确的添加剂，那个就太好了。到目前为止，这个程序非常简单，但是我对这个非常陌生，所以 private void textBox2_TextChanged(object send
textbox1textbox2textbox2private void textBox2_TextChanged(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
if (textBox2.Text == textBox1.Text)
{
label1.Text = "Password Correct";
}
else
{
label1.Text = "Password Wrong";
}
}
private void label1_Click(object sender, EventArgs e)
{
}
需要更多的信息；你是在随机猜测密码吗？字典攻击？你是在按顺序猜密码吗？密码中使用的长度/字符集还有哪些其他限制 我将假设您的程序在UI中自动调用这些尝试，而不是您作为用户。如果是这样的话，我会放弃UI策略，转而使用控制台实现
“随机”猜测问题之所以重要，是因为如果您按顺序猜测，所需的时间长度与您选择的密码直接相关。我不确定你想要什么结果。需要更多信息；你是在随机猜测密码吗？字典攻击？你是在按顺序猜密码吗？密码中使用的长度/字符集还有哪些其他限制 我将假设您的程序在UI中自动调用这些尝试，而不是您作为用户。如果是这样的话，我会放弃UI策略，转而使用控制台实现

已有一些工具可以计算密码强度。为什么您要编写自己的密码，而不是使用其中一个？已有一些工具可以计算密码强度。为什么你要写你自己的而不是使用其中的一个呢？我认为UI部分的出现是因为现在有些人直接从表单和所有这些开始，甚至从来没有意识到他们不需要表单。它是
Console.WriteLine（“你好，世界！”）控制台。WriteLine（“Hello World！”）MessageBox.Show（“Hello World！”）
