AsymmetricAlgorithm.LegalKeySizes Property

Definition

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

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

Property Value

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.

C#
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 + ", ");
    }
}

Remarks

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