Make pyca/cryptography the preferred backend for cryptographic needs (mainly vault) falling back to pycrypto
pyca/cryptography is already implicitly a dependency in many cases
through paramiko (2.0+) as well as the new openssl_publickey module,
which requires pyOpenSSL 16.0+. Additionally, pyca/cryptography is
an optional dep for better performance with vault already.
This commit leverages cryptography's padding, constant time comparisons,
and CBC/CTR modes to reduce the amount of code ansible needs to
maintain.
* Handle wrong password given for VaultAES format
* Do not display deprecation warning for cryptography on python-2.6
* Namespace all of the pycrypto imports and always import them
Makes unittests better and the code less likely to get stupid mistakes
(like using HMAC from cryptogrpahy when the one from pycrypto is needed)
* Add back in atfork since we need pycrypto to reinitialize its RNG just in case we're being used with old paramiko
* contrib/inventory/gce: Remove spurious require on pycrypto
(cherry picked from commit 9e16b9db275263b3ea8d1b124966fdebfc9ab271)
* Add cryptography to ec2_win_password module requirements
* Fix python3 bug which would pass text strings to a function which
requires byte strings.
* Attempt to add pycrypto version to setup deps
* Change hacking README for dual pycrypto/cryptography
* update dependencies for various CI scripts
* additional CI dockerfile/script updates
* add paramiko to the windows and sanity requirement set
This is needed because ansible lists it as a requirement. Previously
the missing dep wasn't enforced, but cryptography imports pkg_resources
so you can't ignore a requirement any more
* Add integration test cases for old vault and for wrong passwords
* helper script for manual testing of pycrypto/cryptography
* Skip the pycrypto tests so that users without it installed can still run the unittests
* Run unittests for vault with both cryptography and pycrypto backend
- Replace nose usage with pytest.
- Remove legacy Shippable integration.sh.
- Update Makefile to use pytest and ansible-test.
- Convert most yield unit tests to pytest parametrize.
* Added aws_retry decorator function with unit tests
* Restructured the code to be used with a base class.
This base class CloudRetry can be reused by any other cloud provider.
This decorator should be used in situations, where you need to implement
a backoff algorithm and want to retry based on the status code from the
exception.
* updated documentation
* fixed tabs
* added botocore and boto3 to requirements.txt
* removed cloud.py from py24 tests, as it depends on boto3
* fix relative imports
* updated test to be 2.6 compat
* updated method name from retry to backoff
* readded lxd
* Updated default backoff from 2 seconds to 1.1s.
This will be about a total of 48 seconds in 10 tries. This is
configurable.
