Hi all,
After reading the docs and loading the necessary 'idea' module, it is
unclear to me whether gnupg can do conventional symmetric encryption,
in a way that is pgp-2 compatible.
Doing the obvious
gpg --verbose --rfc1991 --digest-algo=md5 --compress-algo 1 \
--cipher-algo=idea -c -a -o encrypted.asc plaintext
doesn't seem to work, as
pgp encrypted.asc
complains with
Error: Bad pass phrase.
Going the other way works and gnupg (given the right options) has no
problem decoding pgp-2 symmetrically encrypted messages.
Any ideas, or pointers for further reading ?
Thanks in advance.
