AsymmetricAlgorithm.LegalKeySizes 属性

定义

命名空间:

System.Security.Cryptography

程序集:

System.Security.Cryptography.dll

Source:

AsymmetricAlgorithm.cs

获取非对称算法支持的密钥大小。

public:
 virtual property cli::array <System::Security::Cryptography::KeySizes ^> ^ LegalKeySizes { cli::array <System::Security::Cryptography::KeySizes ^> ^ get(); };

public virtual System.Security.Cryptography.KeySizes[] LegalKeySizes { get; }

member this.LegalKeySizes : System.Security.Cryptography.KeySizes[]

Public Overridable ReadOnly Property LegalKeySizes As KeySizes()

属性值

KeySizes[]

一个数组，它包含非对称算法支持的密钥大小。

示例

下面的代码示例演示如何调用 LegalKeySizes 属性来检索 MinSize、 MaxSize和 SkipSize 属性。 此代码示例是为 AsymmetricAlgorithm 类提供的一个更大示例的一部分。

array<KeySizes^>^ legalKeySizes = customCryptoAlgorithm->LegalKeySizes;
for (int i = 0; i < legalKeySizes->Length; i++)
{
    Console::WriteLine(
        "Keysize{0} min, max, step: {1}, {2}, {3}, ", i,
        legalKeySizes[i]->MinSize,
        legalKeySizes[i]->MaxSize,
        legalKeySizes[i]->SkipSize);
}

KeySizes[] legalKeySizes = customCrypto.LegalKeySizes;
if (legalKeySizes.Length > 0)
{
    for (int i=0; i < legalKeySizes.Length; i++)
    {
        Console.Write("Keysize" + i + " min, max, step: ");
        Console.Write(legalKeySizes[i].MinSize + ", ");
        Console.Write(legalKeySizes[i].MaxSize + ", ");
        Console.WriteLine(legalKeySizes[i].SkipSize + ", ");
    }
}

Dim legalKeySizes() As KeySizes = customCrypto.LegalKeySizes
If (legalKeySizes.Length > 0) Then
    For i As Integer = 0 To legalKeySizes.Length - 1 Step 1
        Write("Keysize" + i.ToString() + " min, max, step: ")
        Write(legalKeySizes(i).MinSize.ToString() + ", ")
        Write(legalKeySizes(i).MaxSize.ToString() + ", ")
        Write(legalKeySizes(i).SkipSize.ToString() + ", ")
        WriteLine("")
    Next
End If

注解

非对称算法仅支持与此数组中的条目匹配的密钥大小。
