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 -> unitPublic Overrides Sub ImportSubjectPublicKeyInfo (source As ReadOnlySpan(Of Byte), ByRef bytesRead As Integer)Parameters
- source
- ReadOnlySpan<Byte>
The bytes of an X.509 SubjectPublicKeyInfo structure in the ASN.1-DER 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
The contents of source do not represent an ASN.1-DER-encoded X.509 SubjectPublicKeyInfo structure.
-or-
The contents of source indicate the key is for an algorithm other than the algorithm represented by this instance.
-or-
The contents of source represent the key in a format that is not supported.
-or-
The algorithm-specific key import failed.
Remarks
This method only supports the binary (DER) encoding of SubjectPublicKeyInfo. If the value is Base64-encoded or in the PEM text format, the caller must Base64-decode the contents before calling this method.
