AsymmetricAlgorithm.ExportEncryptedPkcs8PrivateKey Method

Definition

Overloads

ExportEncryptedPkcs8PrivateKey(ReadOnlySpan<Byte>, PbeParameters)

Exports the current key in the PKCS#8 EncryptedPrivateKeyInfo format with a byte-based password.

ExportEncryptedPkcs8PrivateKey(ReadOnlySpan<Char>, PbeParameters)

Exports the current key in the PKCS#8 EncryptedPrivateKeyInfo format with a char-based password.

ExportEncryptedPkcs8PrivateKey(ReadOnlySpan<Byte>, PbeParameters)

Source:
AsymmetricAlgorithm.cs
Source:
AsymmetricAlgorithm.cs
Source:
AsymmetricAlgorithm.cs

Exports the current key in the PKCS#8 EncryptedPrivateKeyInfo format with a byte-based password.

public:
 virtual cli::array <System::Byte> ^ ExportEncryptedPkcs8PrivateKey(ReadOnlySpan<System::Byte> passwordBytes, System::Security::Cryptography::PbeParameters ^ pbeParameters);
public virtual byte[] ExportEncryptedPkcs8PrivateKey (ReadOnlySpan<byte> passwordBytes, System.Security.Cryptography.PbeParameters pbeParameters);
abstract member ExportEncryptedPkcs8PrivateKey : ReadOnlySpan<byte> * System.Security.Cryptography.PbeParameters -> byte[]
override this.ExportEncryptedPkcs8PrivateKey : ReadOnlySpan<byte> * System.Security.Cryptography.PbeParameters -> byte[]
Public Overridable Function ExportEncryptedPkcs8PrivateKey (passwordBytes As ReadOnlySpan(Of Byte), pbeParameters As PbeParameters) As Byte()

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.

Returns

Byte[]

A byte array containing the PKCS#8 EncryptedPrivateKeyInfo representation of this key.

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).

Exports the current key in the PKCS#8 EncryptedPrivateKeyInfo format with a char-based password.

public:
 virtual cli::array <System::Byte> ^ ExportEncryptedPkcs8PrivateKey(ReadOnlySpan<char> password, System::Security::Cryptography::PbeParameters ^ pbeParameters);

Public Overridable Function ExportEncryptedPkcs8PrivateKey (password As ReadOnlySpan(Of Char), pbeParameters As PbeParameters) As Byte()

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.

Returns

Byte[]

A byte array containing the PKCS#8 EncryptedPrivateKeyInfo representation of this key.

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.
