[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Gets a PublicKey object associated with a certificate.

Namespace:  System.Security.Cryptography.X509Certificates
Assembly:  System.Security (in System.Security.dll)

Syntax

'Declaration
Public ReadOnly Property PublicKey As AsymmetricAlgorithm

public AsymmetricAlgorithm PublicKey { get; }

public:
property AsymmetricAlgorithm^ PublicKey {
    AsymmetricAlgorithm^ get ();
}

member PublicKey : AsymmetricAlgorithm with get

function get PublicKey () : AsymmetricAlgorithm

Property Value

Type: System.Security.Cryptography. . :: . .AsymmetricAlgorithm
A PublicKey object.

Remarks

This property returns a PublicKey object, which contains the object identifier (Oid) representing the public key algorithm, the ASN.1-encoded parameters, and the ASN.1-encoded key value.

You can also obtain the key as an AsymmetricAlgorithm object by referencing the PublicKey property. This property supports only RSA or DSA keys, so it returns either an RSACryptoServiceProvider or a DSACryptoServiceProvider object that represents the public key.
