To get at least little security: filter the user entered password thru the encryption-procedure and compare the result with the file. NEVER (not even in memory) CREATE THE CLEAR-TEXT-PASSWORD. If you need more information about password encryption and password security, i suggest, that you read the group sci.crypt.
