PKG-REPO(8) System Manager's Manual PKG-REPO(8) NAME pkg repo -- create a package repository catalogue SYNOPSIS pkg repo [-hlqs] [-g groups] [-m meta-file] [-o output-dir] <repo-path> [signer-type:<keyfile> | signing_command: <the command>] pkg repo [--{hash,list-files,quiet,symlink}] [--groups groups] [--meta-file meta-file] [--output-dir output-dir] <repo-path> [signer-type:<keyfile> | signing_command: <the command>] DESCRIPTION pkg repo is used to create a catalogue of the available packages in a repository. pkg repo catalogues are necessary for sharing your package repository, and are intrinsic to the operation of pkg install or pkg up- grade. The current repository format is version 2. The repository files created by pkg repo consist of a UCL metadata file and a set of compressed .pkg archives stored at the top level of the repository filesystem. meta.conf is a plain-text UCL file that must exist at the apex of the repository filesystem. It describes the repository version, compression format, and the names of the catalogue archives. See pkg-repository(5) for a detailed description of its fields. packagesite.pkg is a deprecated compressed archive containing packagesite.yaml, which lists the metadata for each of the packages in the repository. Each package manifest is represented as a single-line compact JSON text, with manifests separated by newlines. It is still generated for backward compatibility but is superseded by data.pkg. data.pkg is the primary catalogue archive. It contains a JSON file with package manifests, package group definitions, and expired package entries. See pkg-repository(5) for details. filesite.pkg is an optional compressed archive containing filesite.yaml, a database of all files present in all packages in the repository. It is only generated when the -l flag is used. The compressed archives may also contain cryptographic signatures when the signing mechanism of pkg repo is enabled. Repository users download these files to their local machines, where they are processed into per-repository sqlite databases for fast lookup of available packages by programs such as pkg-install(8). To create a package repository catalogue, specify the top-level directory beneath which all the packages are stored as repo-path. pkg repo will search the filesystem beneath repo-path to find all .pkg files it contains. Directories starting with `.' or named Latest are not traversed. The repository files will be created in the top-level repository directory unless relocated by specifying -o output-dir or --output-dir output-dir. Optionally, the repository catalogue may be cryptographically signed. This is enabled either by specifying the path to a private key as the keyfile argument or by using an external command. When a keyfile is being used, it may be prefixed by the signer type. Currently, this may be one of rsa, ecdsa, or eddsa. ecc is also accepted as an alias of eddsa. Keys for the rsa and ecdsa signers may be generated by OpenSSL or by pkg-key(8). Keys for the "eddsa" signer may only be generated by pkg-key(8). If the key is used, a hash of the repository is signed using the provided key. The rsa signer will sign the SHA256 hash of the repository, while the ecdsa and eddsa signers will sign the BLAKE2 hash of the repository. The signature is added into the repository catalogue. The client side should use SIGNATURE_TYPE set to PUBKEY and PUBKEY set to a local path of the pub- lic key in its repository configuration file. An external command can be useful to create a signing server to keep the private key separate from the repository. The external command is passed the SHA256 of the repository catalogue on its stdin. It should output the following format: TYPE signer type here (rsa, ecdsa, eddsa) SIGNATURE signature data here CERT public key data here END The TYPE field is optional if using rsa, to remain compatible with external signing commands historically in use. Note that the SIGNATURE field's data will may require an extra newline after it if the signature is output in a binary format. The CERT field may contain binary data, but pkg(8) will search the tail of it for the missing END if it runs together. When using an external command, the client's pkg.conf must have SIGNATURE_TYPE set to FINGERPRINTS and FINGERPRINTS set to a directory hav- ing a trusted/myrepo containing a fingerprint style representation of the public key: function: sha256 fingerprint: \"sha256_representation_of_the_public_key\" See the "EXAMPLES" section and pkg.conf(5) for more information. Signing the catalogue is strongly recommended. OPTIONS The following options are supported by pkg repo: -g groups, --groups groups Set the group ownership of the repository files to groups. -h, --hash Append a short hash of the package contents to the package filename. This is the same as setting the PKG_REPO_HASH environment variable. -l, --list-files Generate list of all files in repo as filesite.pkg archive. -m meta-file, --meta-file meta-file Use the specified file as repository meta file instead of the de- fault settings. -o output-dir, --output-dir output-dir Create the repository in the specified directory instead of the package directory. -q, --quiet Force quiet output. -s, --symlink Create a symlink between the hashed filename and the regular file- name. Only useful in combination with -h. This is the same as set- ting the PKG_REPO_SYMLINK environment variable. FILES See pkg.conf(5). ENVIRONMENT PKG_REPO_HASH When set, rename packages with the short hash of contents appended to the filename. PKG_REPO_SYMLINK When set, create a symlink between the short hash file- name and the regular filename.

The public key would be shared on all client servers with SIGNATURE_TYPE set to PUBKEY and its path set via PUBKEY setting in the repository configuration file: pkg repo /usr/ports/packages repo.key Create a repository and sign it with an external command. The client should set, via the repository configuration file, SIGNATURE_TYPE to FINGERPRINTS and FINGERPRINTS to a path containing a file with the SHA256 of the public key: # On signing server: % cat > sign.sh << EOF #!/bin/sh read -t 2 sum [ -z "$sum" ] && exit 1 echo SIGNATURE echo -n $sum | /usr/bin/openssl dgst -sign repo.key -sha256 -binary echo echo CERT cat repo.pub echo END EOF # On package server: % pkg repo /usr/ports/packages signing_command: ssh signing-server sign.sh # Generate fingerprint for sharing with clients % sh -c '( echo "function: sha256"; echo "fingerprint: \"$(sha256 -q repo.pub)\""; ) > fingerprint' # The 'fingerprint' file should be distributed to all clients. # On clients with FINGERPRINTS: /usr/local/etc/pkg/fingerprints/myrepo: $ mkdir -p /usr/local/etc/pkg/fingerprints/myrepo/trusted # Add 'fingerprint' into /usr/local/etc/pkg/fingerprints/myrepo/trusted The above examples can be repeated with OpenSSL creating a key pair for ECDSA: % openssl ecparam -genkey -name secp256k1 -out repo.key -outform DER % chmod 0400 repo.key % openssl ec -in repo.key -out repo.pub -pubout -outform DER Prefixing the later repo.key reference with "ecdsa": pkg repo /usr/ports/packages ecdsa:repo.key The signing server example can be used mostly as-is, but with the following text placed before the SIGNATURE section in the signing server output: TYPE ecdsa For EdDSA instead, create an EdDSA key pair: % pkg key --create -t eddsa repo.key > repo.pub Create a repository and sign it with a local key. As with the RSA example above, the public key would be shared on all client servers with SIGNATURE_TYPE set to PUBKEY and its path set via the PUBKEY option in the repository configuration file: pkg repo /usr/ports/packages eddsa:repo.key A signing server for EdDSA could be constructed with the --sign option.
