-----BEGIN PGP MESSAGE-----

i must say,
that the more i use gnupg,
the more impressed i become,
and think it is the *ultimate* crypto program!
(Thanks to all involved in its development and maintenance !!!)
so,
starting with this strong feeling,
that there just *must* be a way to do this in gnupg,
have found it:
when symmetric encryption is used in pgp,
it uses the preferred hash,
so all that is necessary in gnupg to decrypt it,
is to run gpg --list-packets,
find the symmetric algorithm and hash,
and then put them as option is gpg.conf
so,
since sha-256 and twofish were used,
i put these options back:
cipher-algo twofish
digest-algo SHA256
s2k-cipher-algo twofish
s2k-digest-algo SHA256
then simply used the command:
c:\gnupg>gpg --pgp2 e:\tftjtju.asc
