SymmetricAlgorithm.TryDecryptCbcCore Method

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Source:

SymmetricAlgorithm.cs

When overridden in a derived class, attempts to decrypt data into the specified buffer, using CBC mode with the specified padding mode.

protected:
 virtual bool TryDecryptCbcCore(ReadOnlySpan<System::Byte> ciphertext, ReadOnlySpan<System::Byte> iv, Span<System::Byte> destination, System::Security::Cryptography::PaddingMode paddingMode, [Runtime::InteropServices::Out] int % bytesWritten);

protected virtual bool TryDecryptCbcCore (ReadOnlySpan<byte> ciphertext, ReadOnlySpan<byte> iv, Span<byte> destination, System.Security.Cryptography.PaddingMode paddingMode, out int bytesWritten);

abstract member TryDecryptCbcCore : ReadOnlySpan<byte> * ReadOnlySpan<byte> * Span<byte> * System.Security.Cryptography.PaddingMode * int -> bool
override this.TryDecryptCbcCore : ReadOnlySpan<byte> * ReadOnlySpan<byte> * Span<byte> * System.Security.Cryptography.PaddingMode * int -> bool

Protected Overridable Function TryDecryptCbcCore (ciphertext As ReadOnlySpan(Of Byte), iv As ReadOnlySpan(Of Byte), destination As Span(Of Byte), paddingMode As PaddingMode, ByRef bytesWritten As Integer) As Boolean

Parameters

ciphertext

ReadOnlySpan<Byte>

The data to decrypt.

iv

ReadOnlySpan<Byte>

The initialization vector.

destination

Span<Byte>

The buffer to receive the plaintext data.

paddingMode

PaddingMode

The padding mode used to produce the ciphertext and remove during decryption.

bytesWritten

Int32

When this method returns, contains the total number of bytes written to destination.

Returns

Boolean

true if destination was large enough to receive the decrypted data; otherwise, false.

Exceptions

NotSupportedException

A derived class has not provided an implementation.

Remarks

Derived classes must override this and provide an implementation.
