Yeah, but that's what gets generated when you override the homedir to
an empty directory that doesn't have a gpg.conf file at all. Hence
that is the default.
My regular gpg.conf file has this:
default-preference-list TWOFISH CAMELLIA256 AES256 CAMELLIA192 AES192
CAMELLIA128 AES BLOWFISH IDEA 3DES CAST5 SHA512 SHA384 SHA256 SHA224
RIPEMD160 SHA1 ZLIB BZIP2 ZIP Uncompressed
personal-cipher-preferences TWOFISH CAMELLIA256 AES256 CAMELLIA192
AES192 CAMELLIA128 AES BLOWFISH IDEA 3DES CAST5
personal-digest-preferences SHA512 SHA384 SHA256 SHA224 RIPEMD160 SHA1
personal-compress-preferences ZLIB BZIP2 ZIP Uncompressed

Really? I distinctly recall you recommending TWOFISH to me on
gnupg-users some time ago (following which I did a good deal of
reading on the AES selection process before moving TWOFISH ahead of
Rijndael. Though after reading all that I'd've probably used Serpent
if it had been included with GPG, but it isn't and we don't need to go
through that debate again. Although it is included with gpgsm, but
What else? Oh yeah, ignore the Camellia bits (as most of you do
anyway), that's more because over here in the antipodes and APAC,
there's a greater likelihood of running across correspondents who do
use it and putting it ahead of AES makes it easier to get that
