Gets a PublicKey object associated with a certificate.

Assembly:  System.Security (in System.Security.dll)

member PublicKey : AsymmetricAlgorithm

Property Value

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

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.
