Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Overloads

EncryptCbc(ReadOnlySpan<Byte>, ReadOnlySpan<Byte>, Span<Byte>, PaddingMode)	Encrypts data into the specified buffer, using CBC mode with the specified padding mode.
EncryptCbc(Byte[], Byte[], PaddingMode)	Encrypts data using CBC mode with the specified padding mode.
EncryptCbc(ReadOnlySpan<Byte>, ReadOnlySpan<Byte>, PaddingMode)	Encrypts data using CBC mode with the specified padding mode.

EncryptCbc(ReadOnlySpan<Byte>, ReadOnlySpan<Byte>, Span<Byte>, PaddingMode)

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.

destination

Span<Byte>

The buffer to receive the ciphertext data.

paddingMode

PaddingMode

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

Returns

Int32

The total number of bytes written to destination.

Exceptions

ArgumentOutOfRangeException

paddingMode is not a valid padding mode.

ArgumentException

iv is the incorrect length. Callers are expected to pass an initialization vector that is exactly BlockSize in length, converted to bytes (BlockSize / 8).

CryptographicException

The plaintext could not be encrypted successfully.

ArgumentException

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).

EncryptCbc(Byte[], Byte[], PaddingMode)

Source:

SymmetricAlgorithm.cs

Encrypts data using CBC mode with the specified padding mode.

public byte[] EncryptCbc (byte[] plaintext, byte[] iv, System.Security.Cryptography.PaddingMode paddingMode = System.Security.Cryptography.PaddingMode.PKCS7);

member this.EncryptCbc : byte[] * byte[] * System.Security.Cryptography.PaddingMode -> byte[]

Public Function EncryptCbc (plaintext As Byte(), iv As Byte(), Optional paddingMode As PaddingMode = System.Security.Cryptography.PaddingMode.PKCS7) As Byte()

Parameters

plaintext

Byte[]

The data to encrypt.

iv

Byte[]

The initialization vector.

paddingMode

PaddingMode

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

Returns

Byte[]

The encrypted ciphertext data.

Exceptions

ArgumentNullException

plaintext or iv is null.

ArgumentOutOfRangeException

paddingMode is not a valid padding mode.

ArgumentException

iv is the incorrect length. Callers are expected to pass an initialization vector that is exactly BlockSize in length, converted to bytes (BlockSize / 8).

CryptographicException

The plaintext could not be encrypted successfully.

member this.EncryptCbc : ReadOnlySpan<byte> * ReadOnlySpan<byte> * System.Security.Cryptography.PaddingMode -> byte[]

Public Function EncryptCbc (plaintext As ReadOnlySpan(Of Byte), iv As ReadOnlySpan(Of Byte), Optional paddingMode As PaddingMode = System.Security.Cryptography.PaddingMode.PKCS7) As Byte()

Parameters

plaintext

ReadOnlySpan<Byte>

The data to encrypt.

iv

ReadOnlySpan<Byte>

The initialization vector.

The encrypted ciphertext data.

Exceptions

ArgumentOutOfRangeException

paddingMode is not a valid padding mode.

ArgumentException

iv is the incorrect length. Callers are expected to pass an initialization vector that is exactly BlockSize in length, converted to bytes (BlockSize / 8).

CryptographicException

The plaintext could not be encrypted successfully.
