[Mcrypt-users] Practically dealing with rc6 emcumbered

[Jago P. <ja...@gm...>]

I have a .txt file here encrypted from my phone and... I've forgotten
the password. But it's only 3 letters, probably easier to guess on a
full sized keyboard.

In research I found the program used to encrypt it uses rc6.

At first I thought mcrypt would be able to decrypt straight away. Now
I see I need to specify the algorithm. But I can't see rc6 from
--list.

So more reading and I see that rc6 is propitiatory. More reading still
on mcrypt and I see rc6 referred to as `encumbered`. I take it that
this is referring to that irritating propitiatory status.... which is
why rc6 isn't listed by --list, because the code had to be removed.

...so I guess I have to write the code in myself and patch it in...

I thought I'd try arcfour but it doesn't have ECB-Mode...

I don't think I'll be choosing the phone program to encrypt stuff again!
