Implement ipk signing inside the sign_ipk bbclass using the gpg_sign
module and configure signing similar to how rpm does it. sign_ipk uses
gpg_sign's detach_sign because its functionality is identical to package
feed signing.
IPK signing process is a bit different from rpm:
- Signatures are stored outside ipk files; opkg connects to a feed
server and downloads them to verify a package.
- Signatures are of two types (both supported by opkg): binary or
ascii armoured. By default we sign using ascii armoured.
- Public keys are stored on targets to verify ipks using the
opkg-keyrings recipe.
