core (memory/crypto): replaced `PyCrypto` by `cryptography`:
`PyCrypto` is unmaintained for years but was used in SàT for password hashing. This patch
fixes that by replacing `PyCrypto` by the reference `cryptography` module which is well
maintained.
The behaviour stays the same (except that previously async `hash`, `encrypt` and `decrypt`
methods are now synchronous, as they are quick and using a deferToThread may actually be
more resource intensive than using blocking methods).
It is planed to improve `memory.crypto` by using more up-to-date cryptography/hashing
algorithms in the future.
PyCrypto is no more a dependency of SàT

.. _jp-pubsub_node_schema: ========================================= pubsub/node/schema: nodes schema handling ========================================= ``node schema`` is an experimental feature to associate a data form with a PubSub node, and reject items not following this form. This feature is currently only available with SàT PubSub. Those commands can only be used by an owner of the node. set === Set the schema of a node. The raw schema is written directly as positional argument. example ------- Set the schema for tickets node using the file ``tickets_schema.xml`` from ``$HOME`` directory. Shell substition is used here to put the content of the file in the positional argument:: $ jp pubsub node schema set -n org.salut-a-toi.tickets:0 -s pubsub.example.org "$(<~/test_schema.xml)" edit ==== Edit the schema of a node using your local editor (the one set in ``$EDITOR``). If you don't change anything or publish an empty schema, the edition will be cancelled. :ref:`draft_common` commands can be used. example ------- Edit the tickets node schema:: $ jp pubsub node schema edit -n org.salut-a-toi.tickets:0 -s pubsub.example.org example ------- get === Retrieve schema of a node. example ------- Get schema of tickets and save it to a file named ``tickets_schema.xml`` in ``$HOME`` directory:: $ jp pubsub node schema get -n org.salut-a-toi.tickets:0 -s pubsub.example.org > ~/tickets_schema.xml
