# Fedora packages pycryptodomex, but not pycryptodome (which conflicts with
# pycrypto). Upstream refuses to switch to pycryptodomex for the pycryptodome
# backend (https://github.com/mpdavis/python-jose/issues/26), so we disable the
# corresponding extra because it will fail to install.
#
# We also obsolete the old backend subpackage that required pycryptodomex,
# because it did not do what it claimed to do.

# Upstream release 3.3.0, first packaged in Fedora 35, dropped the pycrypto
# backend, so we obsolete the corresponding extra. The conditional reminds us

# Upstream recommends the cryptography backend. We add it as a soft dependency
# so that anyone who does not go out of their way to select a different backend
# gets the best experience.

%global common_description %{expand:
The JavaScript Object Signing and Encryption (JOSE) technologies - JSON Web
Signature (JWS), JSON Web Encryption (JWE), JSON Web Key (JWK), and JSON Web
Algorithms (JWA) - collectively can be used to encrypt and/or sign content
using a variety of algorithms. While the full set of permutations is extremely
large, and might be daunting to some, it is expected that most applications
will only use a small set of algorithms to meet their needs.

As of 3.3.0, python-jose implements three different cryptographic backends. The
backend must be selected as an extra when installing python-jose. If you do not
select a backend, the native-python backend will be installed.

Unless otherwise noted, all backends support all operations.

Due to complexities with setuptools, the native-python backend is always
installed, even if you select a different backend on install.

  1. cryptography
       * This backend uses pyca/cryptography for all cryptographic operations.
         This is the recommended backend and is selected over all other
         backends if any others are present.
       * Installation: dnf install python3-jose+cryptography
       * Unused dependencies:
           - rsa
           - ecdsa
           - pyasn1

  2. pycryptodome
       * This backend uses pycryptodome for all cryptographic operations.
       * Installation: not available because pycryptodome (which, unlike
                       pycryptodomex, conflicts with pycrypto) is not packaged
       * Unused dependencies:
           - rsa

  3. native-python
       * This backend uses python-rsa and python-ecdsa for all cryptographic
         operations. This backend is always installed but any other backend
         will take precedence if one is installed.
       * Installation: dnf install python3-jose

     Note

     The native-python backend cannot process certificates.}

This is a metapackage bringing in cryptography extras requires for
python3-jose.
It contains no code, just makes sure the dependencies are installed.
