GnuPG 1.03, RSA/IDEA, and cipher-algo preferences
Tue, 19 Sep 2000 14:29:23 -0400
I'm using GnuPG 1.03 with external IDEA support, and I've been able to
successfully use IDEA to send encrypted documents to PGP users with an
RSA key. To accomplish this, I'm using the "--cipher-algo idea" option.
According to gpg(1) :
Use name as cipher algorithm. Running the pro
gram with the command --version yields a list of
supported algorithms. If this is not used the
cipher algorithm is selected from the prefer
ences stored with the key.
This makes it sound like I can associate a default cipher algorithm
preference for each key in my keyring. Unfortunately, I haven't been
able to determine how to set this preference from reading the man pages
or the GnuPG Handbook. I'd love to be able to automatically use IDEA
when encrypting to PGP users and something like 3DES or BLOWFISH when
encrypting to GnuPG users. Can anyone offer any assistance?
