TripleDESCryptoServiceProvider.CreateEncryptor Method

Definition

Namespace:

System.Security.Cryptography

Assemblies:

netstandard.dll, System.Security.Cryptography.dll

Creates a symmetric encryptor object.

Overloads

CreateEncryptor()	Creates a symmetric encryptor object with the current Key property and initialization vector (IV).
CreateEncryptor(Byte[], Byte[])	Creates a symmetric TripleDES encryptor object with the specified key (Key) and initialization vector (IV).

CreateEncryptor()

Source:

TripleDESCryptoServiceProvider.Wrap.cs

Creates a symmetric encryptor object with the current Key property and initialization vector (IV).

public:
 override System::Security::Cryptography::ICryptoTransform ^ CreateEncryptor();

public override System.Security.Cryptography.ICryptoTransform CreateEncryptor();

override this.CreateEncryptor : unit -> System.Security.Cryptography.ICryptoTransform

Public Overrides Function CreateEncryptor () As ICryptoTransform

Returns

ICryptoTransform

A symmetric encryptor object.

Remarks

If the current Key property is null, the GenerateKey method is called to create a new random Key. If the current IV property is null, the GenerateIV method is called to create a new random IV.

Use the CreateDecryptor overload with the same signature to decrypt the result of this method.

CreateEncryptor(Byte[], Byte[])

Source:

TripleDESCryptoServiceProvider.Wrap.cs

Creates a symmetric TripleDES encryptor object with the specified key (Key) and initialization vector (IV).

public:
 override System::Security::Cryptography::ICryptoTransform ^ CreateEncryptor(cli::array <System::Byte> ^ rgbKey, cli::array <System::Byte> ^ rgbIV);

public override System.Security.Cryptography.ICryptoTransform CreateEncryptor(byte[] rgbKey, byte[]? rgbIV);

override this.CreateEncryptor : byte[] * byte[] -> System.Security.Cryptography.ICryptoTransform

Public Overrides Function CreateEncryptor (rgbKey As Byte(), rgbIV As Byte()) As ICryptoTransform

Parameters

rgbKey

Byte[]

The secret key to use for the symmetric algorithm.

rgbIV

Byte[]

The initialization vector to use for the symmetric algorithm.

Note: The initialization vector must be 8 bytes long. If it is longer than 8 bytes, it is truncated and an exception is not thrown. Before you call CreateEncryptor(Byte[], Byte[]), check the length of the initialization vector and throw an exception if it is too long.

Returns

ICryptoTransform

A symmetric TripleDES encryptor object.

Exceptions

CryptographicException

The value of the Mode property is OFB.

-or-

The value of the Mode property is CFB and the value of the FeedbackSize property is not 8.

-or-

An invalid key size was used.

-or-

The algorithm key size was not available.

Remarks

Use the CreateDecryptor overload with the same parameters to decrypt the result of this method.
