File destruction if the password is wrong

If the sender has files that need protection, make the program eat the file, if the password is entered wrong. Give the sender the option to choose the number of tried before the file destructs. The person that got the file, can just request a new copy and explain why they were stupid enough to not copy/paste the prearranged password in the first place. This would actually make this a protection system that works. The sender should be able to send a fresh copy with new password, since we are dealing with digital systems, there is no end to the number of times it can be sent protected. Having one that can be cracked via password hack software, that tries endless combinations, is not really the best way to ensure safe receipt.
