TJwHash Class

Pascal

TJwHash = class;

TJwHash is a class to compute hashes. Both keyless and keyed algorithms are supported. Hashes can also be used to sign data.

	Name	Description
	Create	Creates a new hash object
	Destroy	Destroys the hash object and releases the CSP

TJwHash Methods	The methods of the TJwHash class are listed here.
TJwHash Properties	The properties of the TJwHash class are listed here.

	Name	Description
	FreeBuffer	FreeBuffer frees buffer returned by previous calls to RetrieveHash and Sign .
	GetHashLength	GetHashLength returns the size of the hash value in bytes. This value is constant for each algorithm.
	GetSignatureLength	This function returns the length of the signature for subsequent calls to the Sign routine.
	HashData	Adds data to the hash object
	HashStream	Adds data to the hash object
	RetrieveHash	This is the overview for the RetrieveHash method overload.
	Sign	This is the overview for the Sign method overload.
	VerifySignature	VerifySignature verifies that the given signature is correct for the data previously added to the hash using HashData .

	Name	Description
	Algorithm	The algorithm specified in the call to create EJwsclHashApiException will be raised if the underlying Windows call fails.
	HashHandle	HashHandle is the handle to the hash object.
