RSA.ImportPkcs8PrivateKey(ReadOnlySpan<Byte>, Int32) 方法

定義

解密後,從 PKCS#8 PrivateKeyInfo 結構匯入公開/私密金鑰組,以取代這個物件的金鑰。Imports the public/private keypair from a PKCS#8 PrivateKeyInfo structure after decryption, replacing the keys for this object.

public:
 override void ImportPkcs8PrivateKey(ReadOnlySpan<System::Byte> source, [Runtime::InteropServices::Out] int % bytesRead);
public override void ImportPkcs8PrivateKey (ReadOnlySpan<byte> source, out int bytesRead);
override this.ImportPkcs8PrivateKey : ReadOnlySpan<byte> * int -> unit
Public Overrides Sub ImportPkcs8PrivateKey (source As ReadOnlySpan(Of Byte), ByRef bytesRead As Integer)

參數

source
ReadOnlySpan<Byte>

以 ASN.1-BER 編碼的 PKCS#8 PrivateKeyInfo 結構位元組。The bytes of a PKCS#8 PrivateKeyInfo structure in the ASN.1-BER encoding.

bytesRead
Int32

當此方法傳回時,會包含一個值,指出讀取自 source 的位元組數。When this method returns, contains a value that indicates the number of bytes read from source. 這個參數會被視為未初始化。This parameter is treated as uninitialized.

例外狀況

source 的內容不表示 ASN.1-BER 編碼的 PKCS#8 PrivateKeyInfo 結構。The contents of source do not represent an ASN.1-BER-encoded PKCS#8 PrivateKeyInfo structure.

-或--or-

source 的內容指出金鑰適用於這個執行個體所表示演算法以外的演算法。The contents of source indicate the key is for an algorithm other than the algorithm represented by this instance.

-或--or-

source 的內容表示金鑰的格式不受支援。The contents of source represent the key in a format that is not supported.

-或--or-

演算法專屬金鑰匯入失敗。The algorithm-specific key import failed.

備註

這個方法只支援 PrivateKeyInfo) 編碼的 binary (BER/CER/DER 編碼。This method only supports the binary (BER/CER/DER) encoding of PrivateKeyInfo. 如果值是 Base64 編碼或 PEM 文字格式,呼叫端必須在呼叫這個方法之前,先將內容設定為 Base64。If the value is Base64-encoded or in the PEM text format, the caller must Base64-decode the contents before calling this method.
