PrivateKey Property

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

Gets or sets the AsymmetricAlgorithm object that represents the private key associated with a certificate.

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

public AsymmetricAlgorithm PrivateKey { get; }

Property Value

Type: System.Security.Cryptography..::..AsymmetricAlgorithm
An AsymmetricAlgorithm object, which is either an RSA or DSA cryptographic service provider.

Currently this property supports only RSA or DSA keys, so it returns either an RSACryptoServiceProvider or a DSACryptoServiceProvider object. If no private key is associated with the certificate, it returns nullNothingnullptrunita null reference (Nothing in Visual Basic).

Caution noteCaution

If you set this property to nullNothingnullptrunita null reference (Nothing in Visual Basic) or to another key without first deleting it, a private key file is left on the disk.
