ECAlgorithm.ImportECPrivateKey(ReadOnlySpan<Byte>, Int32) Method

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Source:

ECAlgorithm.cs

Imports the public/private keypair from an ECPrivateKey structure, replacing the keys for this object.

public:
 virtual void ImportECPrivateKey(ReadOnlySpan<System::Byte> source, [Runtime::InteropServices::Out] int % bytesRead);

public virtual void ImportECPrivateKey (ReadOnlySpan<byte> source, out int bytesRead);

abstract member ImportECPrivateKey : ReadOnlySpan<byte> * int -> unit
override this.ImportECPrivateKey : ReadOnlySpan<byte> * int -> unit

Public Overridable Sub ImportECPrivateKey (source As ReadOnlySpan(Of Byte), ByRef bytesRead As Integer)

Parameters

source

ReadOnlySpan<Byte>

The bytes of an ECPrivateKey structure in the ASN.1-BER encoding.

bytesRead

Int32

When this method returns, contains a value that indicates the number of bytes read from source. This parameter is treated as uninitialized.

Exceptions

NotSupportedException

A derived class has not provided an implementation for ImportParameters(ECParameters).

CryptographicException

The contents of source do not represent an ASN.1-BER-encoded PKCS#8 ECPrivateKey structure.

-or-

The key import failed.

Remarks

This method only supports the binary (BER/CER/DER) encoding of ECPrivateKey. If the value is Base64-encoded, the caller must Base64-decode the contents before calling this method. If the value is PEM-encoded, ImportFromPem(ReadOnlySpan<Char>) should be used.
