Attempts to export the current key in the PKCS#8 EncryptedPrivateKeyInfo format into a provided buffer, using a char-based password.
public:
override bool TryExportEncryptedPkcs8PrivateKey(ReadOnlySpan<char> password, System::Security::Cryptography::PbeParameters ^ pbeParameters, Span<System::Byte> destination, [Runtime::InteropServices::Out] int % bytesWritten);
public override bool TryExportEncryptedPkcs8PrivateKey (ReadOnlySpan<char> password, System.Security.Cryptography.PbeParameters pbeParameters, Span<byte> destination, out int bytesWritten);
override this.TryExportEncryptedPkcs8PrivateKey : ReadOnlySpan<char> * System.Security.Cryptography.PbeParameters * Span<byte> * int -> bool
Public Overrides Function TryExportEncryptedPkcs8PrivateKey (password As ReadOnlySpan(Of Char), pbeParameters As PbeParameters, destination As Span(Of Byte), ByRef bytesWritten As Integer) As Boolean
Parameters
- password
- ReadOnlySpan<Char>
The password to use when encrypting the key material.
- pbeParameters
- PbeParameters
The password-based encryption (PBE) parameters to use when encrypting the key material.
- bytesWritten
- Int32
When this method returns, contains a value that indicates the number of bytes written to destination
. This parameter is treated as uninitialized.
Returns
true
if destination
is big enough to receive the output; otherwise, false
.
Exceptions
The key could not be exported.
Remarks
When pbeParameters
indicates an algorithm that uses PBKDF2 (Password-Based Key Derivation Function 2), the password is converted to bytes via the UTF-8 encoding.

override this.TryExportEncryptedPkcs8PrivateKey : ReadOnlySpan<byte> * System.Security.Cryptography.PbeParameters * Span<byte> * int -> bool
Public Overrides Function TryExportEncryptedPkcs8PrivateKey (passwordBytes As ReadOnlySpan(Of Byte), pbeParameters As PbeParameters, destination As Span(Of Byte), ByRef bytesWritten As Integer) As Boolean
Parameters
- passwordBytes
- ReadOnlySpan<Byte>
The bytes to use as a password when encrypting the key material.
- pbeParameters
- PbeParameters
The password-based encryption (PBE) parameters to use when encrypting the key material.
- bytesWritten
- Int32
When this method returns, contains a value that indicates the number of bytes written to destination
. This parameter is treated as uninitialized.
Returns
true
if destination
is big enough to receive the output; otherwise, false
.
Exceptions
The key could not be exported.
-or-
pbeParameters
indicates that TripleDes3KeyPkcs12 should be used, which requires Char-based passwords.
Remarks
The password bytes are passed directly into the Key Derivation Function (KDF) used by the algorithm indicated by pbeParameters
.
This enables compatibility with other systems which use a text encoding other than UTF-8 when processing passwords with PBKDF2 (Password-Based Key Derivation Function 2).
