Pascal

function JwLoadHashFromRegistry(const Hive: Cardinal; const Key: String; const HashName: String; const SizeName: String): TJwFileHashData;

Parameters	Description
const Hive: Cardinal	Defines a registry hive like HKEY_LOCAL_MACHINE.
const Key: String	Defines a registry path to a key like "SoftwareJEDI".
const HashName: String	Defines the registry value name that receives the hash data.
const SizeName: String	Defines the registry value name that receives the size of hash data.

The return value is a record that holds the hash data. The returned pointer member "hash" in TJwFileHashData must be freed by TJwHash.FreeBuffer (unit JwsclCryptProvider.pas).

raise ERegistryException If the given key was not found. Exception This procedure may raise exception coming from TRegistry methods.

JwLoadHashFromRegistry loads a hash record (TJwFileHashData) to registry previously saved by JwSaveHashToRegistry.

The procedure has some characteristics :

It does not check for a correct hash value. However the key type of "HashName" must be binary though.
It only returns a valid structure if the value from key "SizeName" is between 1 than 1023 bytes (1 <= SizeName <= 1023)
