There's no reason at this point to mimic the calling convention of the 'openssl' command. * nix/libstore/local-store.cc (LocalStore::exportPath): Add only "sign" and HASH to ARGS. Remove 'tmpDir' and 'hashFile'. (LocalStore::importPath): Add only "verify" and SIGNATURE to * guix/scripts/authenticate.scm (guix-authenticate): Adjust accordingly; remove the OpenSSL-style clauses. (read-hash-data): Remove. (sign-with-key): Replace 'port' with 'sha256' and adjust accordingly. (validate-signature): Export SIGNATURE to be a canonical sexp. * tests/guix-authenticate.sh: Adjust tests accordingly.
