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

Definition

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

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

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

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

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.
