Actually, attaching the already encrypted file is pretty much useless.
I experimented some, with the attached toy input file (compressed with 7-zip to
avoid a huge attachment), and found that the issue seems to be related to
writing *new* files somehow.
If I create an encrypted output file as follows, everything works fine:
:e encrypt_in.txt
:saveas encrypt_blowfish2.txt
:X
password
password
:w
However, if I encrypt as follows, I see the E381 error repeated a bunch of
times, and Vim seems to hang if I quit that error and try the password again
and write, presumably creating that giant file the OP mentioned:
:r encrypt_in.txt
ggdd
:X
password
password
:w encrypt_blowfish2.txt
Oddly enough, this also fails:
:r encrypt_in.txt
ggdd
:w encrypt_blowfish2.txt
:X
password
password
:w
But this succeeds (after a really long time):
:r encrypt_in.txt
ggdd
:w encrypt_blowfish2.txt
:e
:X
password
password
:w
It seems to be related to encrypting the swapfile for the new file. This fails:
:set swapfile noundofile
:r encrypt_in.txt
ggdd
:X
password
password
:w encrypt_blowfish2.txt
But this succeeds:
:set noswapfile undofile
:r encrypt_in.txt
ggdd
:X
password
password
:w encrypt_blowfish2.txt
