This question already has an answer here:
I already created a PGP key-pair in Thunderbird Enigmail on Ubuntu. Now I would like to change the key, so it uses preferably Camellia-256 for encryption.
How can I change the preferred algorithm from AES 256 to Camellia-256 in my existing key?
I want to find out how to add the information that I prefer CAMELLIA256 to my already existing PGP key. I guess this can be done using the commandline somehow like
gpg2 --edit-key ...
setpref CAMELLIA256 somehow, but I cannot find a good site that explains this syntax
