PublicKey(AsymmetricAlgorithm)

Source:
PublicKey.cs
Source:
PublicKey.cs
Source:
PublicKey.cs
Source:
PublicKey.cs
Source:
PublicKey.cs

Initializes a new instance of the PublicKey class using SubjectPublicKeyInfo from an AsymmetricAlgorithm.

public:
 PublicKey(System::Security::Cryptography::AsymmetricAlgorithm ^ key);
public PublicKey(System.Security.Cryptography.AsymmetricAlgorithm key);
new System.Security.Cryptography.X509Certificates.PublicKey : System.Security.Cryptography.AsymmetricAlgorithm -> System.Security.Cryptography.X509Certificates.PublicKey
Public Sub New (key As AsymmetricAlgorithm)

Parameters

key
AsymmetricAlgorithm

An asymmetric algorithm to obtain the SubjectPublicKeyInfo from.

Exceptions

The SubjectPublicKeyInfo could not be decoded. The ExportSubjectPublicKeyInfo() must return a valid ASN.1-DER encoded X.509 SubjectPublicKeyInfo.

ExportSubjectPublicKeyInfo() has not been overridden in a derived class.
