A better solution is to stop paying to ISP which does not provide you
with what you have paid for.

Since one can easily encrypt >60 Mb/s with AES on a modern computer it
does not matter what algorithm to use (unless, of course, you have a
wider than 60 MB/s connection).

BTW, if ISP really wants to slow down bittorrent it can use some other
methods: there is usually constant port (6881, IIRC), and quite
specific communication patern.
