Creates a key from algorithm and password
#include <Crypt.au3>
_Crypt_DeriveKey ( $vPassword, $iAlgID [, $iHashAlgID = $CALG_MD5] )
$vPassword | Password to use |
$iAlgID | Encryption ID of algorithm to be used with the key |
$iHashAlgID | [optional] Id of the algo to hash the password with |
Success: | a handle to a cryptographic key. |
Failure: | -1 and sets the @error flag to non-zero. |
@error: | 10 - Failed to create hash object 20 - Failed to hash password 30 - Failed to generate key |
The key needs to be destroyed with _Crypt_DestroyKey().
