SymmetricAlgorithm.TryEncryptCbcCore Method
Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
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.
- 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
true
if destination
was large enough to receive the encrypted data; otherwise, false
.
Exceptions
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
.
