As promised :) here is a patch allowing opkg to authenticate
a package list using smime and openssl instead of gpgme

Example:

 Sign a package list:
openssl smime -sign -in /path/to/repo/Packages \
       -signer /root/server.pem -binary \
       -outform PEM -out /path/to/repo/Packages.sig

 Configuration in /etc/opkg/opkg.conf
option check_signature 1
option signature_ca_file /etc/serverCA.pem
 option signature_ca_path /path/to/certs/dir

 opkg update
Downloading http://repo:8000/Packages
Updated list of available packages in /usr/lib/opkg/lists/angstrom
Downloading http://repo:8000/Packages.sig
Signature check passed

 Package list corruption or MIM:
Downloading http://repo:8000/Packages
Updated list of available packages in /usr/lib/opkg/lists/angstrom
Downloading http://repo:8000/Packages.sig
Signature check failed
