AlgorithmIdentifier Constructors

Definition

Namespace:

System.Security.Cryptography.Pkcs

Assembly:

System.Security.Cryptography.Pkcs.dll

Overloads

AlgorithmIdentifier()	The AlgorithmIdentifier() constructor creates an instance of the AlgorithmIdentifier class by using a set of default parameters.
AlgorithmIdentifier(Oid)	The AlgorithmIdentifier(Oid) constructor creates an instance of the AlgorithmIdentifier class with the specified algorithm identifier.
AlgorithmIdentifier(Oid, Int32)	The AlgorithmIdentifier(Oid, Int32) constructor creates an instance of the AlgorithmIdentifier class with the specified algorithm identifier and key length.

AlgorithmIdentifier()

Source:

AlgorithmIdentifier.cs

The AlgorithmIdentifier() constructor creates an instance of the AlgorithmIdentifier class by using a set of default parameters.

C#

public AlgorithmIdentifier();

Exceptions

CryptographicException

A cryptographic operation could not be completed.

Remarks

The AlgorithmIdentifier class has the following default property values.

Property	Default value
Oid	1.2.840.113549.3.7 (RSA_DES_EDE3_CBC)
KeyLength	The maximum provided by the default Cryptographic Service Provider

To gain the highest degree of control over an application constructing an instance of this class, use one of the constructors that allows the algorithm to be set by passing in its Oid object. This guards against the possibility that the default algorithm could change because of security or other considerations.

AlgorithmIdentifier(Oid)

Source:

AlgorithmIdentifier.cs

The AlgorithmIdentifier(Oid) constructor creates an instance of the AlgorithmIdentifier class with the specified algorithm identifier.

C#

public AlgorithmIdentifier(System.Security.Cryptography.Oid oid);

Parameters

oid

Oid

An object identifier for the algorithm.

Exceptions

CryptographicException

A cryptographic operation could not be completed.

Remarks

For the default property values used with this constructor, see AlgorithmIdentifier().

AlgorithmIdentifier(Oid, Int32)

Source:

AlgorithmIdentifier.cs

The AlgorithmIdentifier(Oid, Int32) constructor creates an instance of the AlgorithmIdentifier class with the specified algorithm identifier and key length.

C#

public AlgorithmIdentifier(System.Security.Cryptography.Oid oid, int keyLength);

Parameters

oid

Oid

An object identifier for the algorithm.

keyLength

Int32

The length, in bits, of the key.

Exceptions

CryptographicException

A cryptographic operation could not be completed.

Remarks

The keyLength parameter is ignored for algorithms that use a fixed key length.
