public class CryptoServiceProvider : IDisposable

Public Class CryptoServiceProvider
	Implements IDisposable

The CryptoServiceProvider type exposes the following members.

Constructors

	Name	Description

Methods

	Name	Description
	Dispose	Releases the resources associated with the current CryptoServiceProvider object.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetKeyContainer	Gets the name of the key container.
	GetProviderName	Gets the name of the CSP represented by this object.
	GetProviderVersion	Gets the version of the CSP represented by this object.
	GetSupportedAlgorithms	Gets the array of all cryptographic algorithms supported by the CSP.
	GetSystemProviders	Gets the list of all CPSs that are registered in the operating system.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Fields

	Name	Description
	Base	Gets Microsoft Base Cryptographic Provider name.
	Enhanced	Gets Microsoft Enhanced Cryptographic Provider name.
	Strong	Gets Microsoft Strong Cryptographic Provider name.

Properties

	Name	Description
	LastResult	Gets a numeric code of the last error.
	ThrowExceptions	Gets or sets whether the object will throw exceptions on errors.

Remarks

CSP is an independent software module which performs cryptographic algorithms for authentication, encoding and encryption procedures. Each CSP supports its own set of algorithms.

Note
MailBee handles CSPs automatically. Usually there is no need to use CryptoServiceProvider class unless you need to use specific CSP. Although Smime class does offer Provider property, it's ignored by most editions of MailBee.NET Objects library.

Note
UWP and .NET Standard 2.0+ editions don't support this class at all. With these editions, the class is not defined or has no public members.

Examples

This sample displays the details of the default CSP to be used by MailBee, then changes the default CSP and displays its details, then creates a new CSP and displays its details.

Copy

// To use the code below, import these namespace at the top of your code
using System;
using MailBee.Security;

// The actual code (put it into a method of your class)

Smime objSmime = new Smime();

// Use default CSP.
Console.WriteLine(objSmime.Provider.GetProviderName());
Console.WriteLine(objSmime.Provider.GetProviderVersion());
Console.WriteLine(objSmime.Provider.GetKeyContainer());
Console.WriteLine("-----------------------------------");

// Set new default for CSP.
objSmime.Provider = new CryptoServiceProvider(CryptoServiceProvider.Enhanced);

// Use the new default CSP.
Console.WriteLine(objSmime.Provider.GetProviderName());
Console.WriteLine(objSmime.Provider.GetProviderVersion());
Console.WriteLine(objSmime.Provider.GetKeyContainer());
Console.WriteLine("-----------------------------------");

// Set new default for CSP.
CryptoServiceProvider strongProvider = new CryptoServiceProvider(CryptoServiceProvider.Strong);
objSmime.Provider = strongProvider;

// Use another CSP.
Console.WriteLine(objSmime.Provider.GetProviderName());
Console.WriteLine(objSmime.Provider.GetProviderVersion());
Console.WriteLine(objSmime.Provider.GetKeyContainer());
Console.WriteLine("-----------------------------------");

' To use the code below, import MailBee namespace at the top of your code
