ECDiffieHellman.ImportSubjectPublicKeyInfo(ReadOnlySpan<Byte>, Int32) 方法

定义

解密后,从 X.509 SubjectPublicKeyInfo 结构中导入公钥,以替换此对象的密钥。Imports the public key from an X.509 SubjectPublicKeyInfo structure after decryption, replacing the keys for this object.

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

参数

source
ReadOnlySpan<Byte>

ASN.1-DER 编码中的 X.509 SubjectPublicKeyInfo 结构的字节。The bytes of an X.509 SubjectPublicKeyInfo structure in the ASN.1-DER encoding.

bytesRead
Int32

此方法返回时,包含一个指示从 source 中读取的字节数的值。When this method returns, contains a value that indicates the number of bytes read from source. 该参数未经初始化即被处理。This parameter is treated as uninitialized.

异常

source 的内容不表示 ASN.1-DER 编码的 X.509 SubjectPublicKeyInfo 结构。The contents of source do not represent an ASN.1-DER-encoded X.509 SubjectPublicKeyInfo structure.

-or-

source 的内容指示密钥用于此实例表示的算法以外的算法。The contents of source indicate the key is for an algorithm other than the algorithm represented by this instance.

-or-

source 的内容表示密钥采用的格式不受支持。The contents of source represent the key in a format that is not supported.

-or-

特定于算法的密钥导入失败。The algorithm-specific key import failed.

注解

此方法只支持 SubjectPublicKeyInfo 的二进制(DER)编码。This method only supports the binary (DER) encoding of SubjectPublicKeyInfo. 如果值采用 Base64 编码或 PEM 文本格式,则调用方必须在调用此方法之前对内容进行 Base64 编码。If the value is Base64-encoded or in the PEM text format, the caller must Base64-decode the contents before calling this method.
