AsymmetricAlgorithm.LegalKeySizes Property

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

Namespace: System.Security.Cryptography
Assembly: mscorlib (in mscorlib.dll)

public virtual KeySizes[] LegalKeySizes { get; }
/** @property */
public KeySizes[] get_LegalKeySizes ()

public function get LegalKeySizes () : KeySizes[]

Property Value

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

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

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.

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 + ", ");
