- Source:
- SymmetricAlgorithm.cs
- Source:
- SymmetricAlgorithm.cs
- Source:
- SymmetricAlgorithm.cs
Encrypts data into the specified buffer, using CBC mode with the specified padding mode.
public int EncryptCbc (ReadOnlySpan<byte> plaintext, ReadOnlySpan<byte> iv, Span<byte> destination, System.Security.Cryptography.PaddingMode paddingMode = System.Security.Cryptography.PaddingMode.PKCS7);
member this.EncryptCbc : ReadOnlySpan<byte> * ReadOnlySpan<byte> * Span<byte> * System.Security.Cryptography.PaddingMode -> int
Public Function EncryptCbc (plaintext As ReadOnlySpan(Of Byte), iv As ReadOnlySpan(Of Byte), destination As Span(Of Byte), Optional paddingMode As PaddingMode = System.Security.Cryptography.PaddingMode.PKCS7) As Integer
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.
Returns
The total number of bytes written to destination
.
Exceptions
paddingMode
is not a valid padding mode.
iv
is the incorrect length. Callers are expected to pass an initialization vector that is exactly BlockSize in length, converted to bytes (BlockSize / 8
).
The plaintext could not be encrypted successfully.
The buffer in destination
is too small to hold the ciphertext data.
Remarks
This method's behavior is defined by TryEncryptCbcCore(ReadOnlySpan<Byte>, ReadOnlySpan<Byte>, Span<Byte>, PaddingMode, Int32).
