File

JwsclCryptProvider

Description

TJwCryptKey encapsulates CAPI keys. Keys for symmetric and asymmetric algorithms are supported. They can be used for hash computing. Keys can be created by retrieving the user keys of a CSP, randomly generating a new key, deriving from base data and importing from a data blob.

	Name	Description
	Create	Duplicates an existing key.
	Derive	Derives a key from a specified seed
	Destroy	Destroys the key
	Generate	Randomly generates a key
	GenerateContainerKey	Randomly generates a public/private key pair and stores it in the key container of the specified CSP. The new key replaces the old key (if existing) in the container. Thus, this constructor is generally used in the following way:
	GetUserKey	Gets one of the two standard key pairs of the specified CSP.
	Import	Imports a key from a data blob

TJwCryptKey Methods

	Name	Description
	Decrypt	This function decrypts a data block. It trashes the encrypted data.
	Encrypt	This function encrypts a data block. It trashes the original data.
	ExportKey	This is the overview for the ExportKey method overload.
	FreeBuffer	FreeBuffer frees buffer returned by previous calls to ExportKey .
	GetExportKeyLength	GetExportKeyLength can be used to determine the length of the export blob for subsequent calls to ExportKey .
	GetKeyParam	This function can be used to retrieve certain parameters of the key. It is mostly for internal use. See http://msdn2.microsoft.com/en-us/library/aa379949.aspx for more information.

TJwCryptKey Properties

	Name	Description
	BlockLen	The block size of the key. This is zero for stream ciphers. If the key is a public/private key pair, the encryption granularity is returned.
	Handle	The handle to the key
	KeyLen	The length of the key, as specified upon key creation
