How do I detect and possibly change the encryption algorithm used by Vim's "encrypt" mode?

Question

I'd like to start using "vim -X" to store encrypted text files. This is a nice introduction on how to do it:

However, how do I tell for sure what encryption algorithm is being used, and how do a change it to blowfish if it's the older, less secure algorithm?

You can check the current encryption method by checking the cryptmethod variable, like so:

:set cryptmethod
  cryptmethod=zip

Vim only supports zip and blowfish at the moment, where Blowfish is the stronger method.

Thanks, that does it. Word of warning, the cryptmethod variable is available in vim7.3 but not 7.2. That's why a couldn't find it. I was on an Ubuntu10.04LTS machine which uses 7.2. – Peter Groves Jul 27 '12 at 15:08
p.s. I'd upvote you but I don't have the minimum karma to upvote. – Peter Groves Jul 27 '12 at 15:09
