Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Overloads

DecryptEcb(Byte[], PaddingMode)	Decrypts data using ECB mode with the specified padding mode.
DecryptEcb(ReadOnlySpan<Byte>, PaddingMode)	Decrypts data using ECB mode with the specified padding mode.
DecryptEcb(ReadOnlySpan<Byte>, Span<Byte>, PaddingMode)	Decrypts data into the specified buffer, using ECB mode with the specified padding mode.

DecryptEcb(Byte[], PaddingMode)

Source:

SymmetricAlgorithm.cs

Decrypts data using ECB mode with the specified padding mode.

public:
 cli::array <System::Byte> ^ DecryptEcb(cli::array <System::Byte> ^ ciphertext, System::Security::Cryptography::PaddingMode paddingMode);

public byte[] DecryptEcb (byte[] ciphertext, System.Security.Cryptography.PaddingMode paddingMode);

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

Public Function DecryptEcb (ciphertext As Byte(), paddingMode As PaddingMode) As Byte()

Parameters

ciphertext

Byte[]

The data to decrypt.

paddingMode

PaddingMode

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

Returns

Byte[]

The decrypted plaintext data.

Exceptions

ArgumentNullException

ciphertext is null.

ArgumentOutOfRangeException

paddingMode is not a valid padding mode.

CryptographicException

The ciphertext could not be decrypted successfully.

Remarks

This method's behavior is defined by TryDecryptEcbCore(ReadOnlySpan<Byte>, Span<Byte>, PaddingMode, Int32).

DecryptEcb(ReadOnlySpan<Byte>, PaddingMode)

Source:

SymmetricAlgorithm.cs

Returns

Byte[]

The decrypted plaintext data.

Exceptions

ArgumentOutOfRangeException

paddingMode is not a valid padding mode.

CryptographicException

The ciphertext could not be decrypted successfully.

Remarks

This method's behavior is defined by TryDecryptEcbCore(ReadOnlySpan<Byte>, Span<Byte>, PaddingMode, Int32).

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

Source:

SymmetricAlgorithm.cs

Decrypts data into the specified buffer, using ECB mode with the specified padding mode.

public:
 int DecryptEcb(ReadOnlySpan<System::Byte> ciphertext, Span<System::Byte> destination, System::Security::Cryptography::PaddingMode paddingMode);

public int DecryptEcb (ReadOnlySpan<byte> ciphertext, Span<byte> destination, System.Security.Cryptography.PaddingMode paddingMode);

member this.DecryptEcb : ReadOnlySpan<byte> * Span<byte> * System.Security.Cryptography.PaddingMode -> int

Public Function DecryptEcb (ciphertext As ReadOnlySpan(Of Byte), destination As Span(Of Byte), paddingMode As PaddingMode) As Integer

Parameters

ciphertext

ReadOnlySpan<Byte>

The data to decrypt.

destination

Span<Byte>

The buffer to receive the plaintext 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.

CryptographicException

The ciphertext could not be decrypted successfully.

ArgumentException

The buffer in destination is too small to hold the plaintext data.
