SymmetricAlgorithm.TryEncryptCbcCore Method

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Source:

SymmetricAlgorithm.cs

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

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

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

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

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

Parameters

plaintext

ReadOnlySpan<Byte>

The data to encrypt.

iv

ReadOnlySpan<Byte>

The initialization vector.

destination

Span<Byte>

The buffer to receive the ciphertext 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 encrypted data; otherwise, false.

Exceptions

NotSupportedException

A derived class has not provided an implementation.

Remarks

Derived classes must override this and provide an implementation.

Implementations of this method must write precisely GetCiphertextLengthCbc(plaintext.Length, paddingMode) bytes to destination and report that via bytesWritten.
