Vim 7.2.446 is following behavior:
:echo has('cryptv')
1
:set cryptmethod?
E518: Unknown option: cryptmethod?
Therefore, it is undesirable to use the has('cryptv').
In this case you should use the exists("+cryptmethod").
Following function may useful for you.
function! HasBlowfish()
let ret = 0
if exists("+cryptmethod")
let cm_save = &g:cryptmethod
let ret = 1
try
setg cryptmethod=blowfish
catch
let ret = 0
endtry
let &g:cryptmethod = cm_save
endif
return ret
endfunc
It will also be able to correspond to the blowfish2 with a little ingenuity.
