DESCryptoServiceProvider.CreateDecryptor Method

Definition

Namespace:

System.Security.Cryptography

Assemblies:

netstandard.dll, System.Security.Cryptography.dll

Overloads

CreateDecryptor()	Creates a symmetric decryptor object with the current Key property and initialization vector (IV).
CreateDecryptor(Byte[], Byte[])	Creates a symmetric Data Encryption Standard (DES) decryptor object with the specified key (Key) and initialization vector (IV).

CreateDecryptor()

Source:

DESCryptoServiceProvider.Unix.cs

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

C#

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

Returns

ICryptoTransform

A symmetric decryptor object.

Remarks

This method decrypts an encrypted message created using the CreateEncryptor overload with the same signature.

CreateDecryptor(Byte[], Byte[])

Source:

DESCryptoServiceProvider.Unix.cs

Creates a symmetric Data Encryption Standard (DES) decryptor object with the specified key (Key) and initialization vector (IV).

C#

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

Parameters

rgbKey

Byte[]

The secret key to use for the symmetric algorithm.

rgbIV

Byte[]

The initialization vector to use for the symmetric algorithm.

Returns

ICryptoTransform

A symmetric DES decryptor 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

This method decrypts an encrypted message that was created using the CreateEncryptor overload with the same parameters.
