AsymmetricAlgorithm.LegalKeySizes Property

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Source:

AsymmetricAlgorithm.cs

Gets the key sizes that are supported by the asymmetric algorithm.

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()

Property Value

KeySizes[]

An array that contains the key sizes supported by the asymmetric algorithm.

Examples

The following code example demonstrates how to call the LegalKeySizes property to retrieve the MinSize, MaxSize, and SkipSize properties. This code example is part of a larger example provided for the AsymmetricAlgorithm class.

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

Remarks

The asymmetric algorithm supports only key sizes that match an entry in this array.
