Fixes#13243
** Add --vault-id to name/identify multiple vault passwords
Use --vault-id to indicate id and path/type
--vault-id=prompt # prompt for default vault id password
--vault-id=myorg@prompt # prompt for a vault_id named 'myorg'
--vault-id=a_password_file # load ./a_password_file for default id
--vault-id=myorg@a_password_file # load file for 'myorg' vault id
vault_id's are created implicitly for existing --vault-password-file
and --ask-vault-pass options.
Vault ids are just for UX purposes and bookkeeping. Only the vault
payload and the password bytestring is needed to decrypt a
vault blob.
Replace passing password around everywhere with
a VaultSecrets object.
If we specify a vault_id, mention that in password prompts
Specifying multiple -vault-password-files will
now try each until one works
** Rev vault format in a backwards compatible way
The 1.2 vault format adds the vault_id to the header line
of the vault text. This is backwards compatible with older
versions of ansible. Old versions will just ignore it and
treat it as the default (and only) vault id.
Note: only 2.4+ supports multiple vault passwords, so while
earlier ansible versions can read the vault-1.2 format, it
does not make them magically support multiple vault passwords.
use 1.1 format for 'default' vault_id
Vaulted items that need to include a vault_id will be
written in 1.2 format.
If we set a new DEFAULT_VAULT_IDENTITY, then the default will
use version 1.2
vault will only use a vault_id if one is specified. So if none
is specified and C.DEFAULT_VAULT_IDENTITY is 'default'
we use the old format.
** Changes/refactors needed to implement multiple vault passwords
raise exceptions on decrypt fail, check vault id early
split out parsing the vault plaintext envelope (with the
sha/original plaintext) to _split_plaintext_envelope()
some cli fixups for specifying multiple paths in
the unfrack_paths optparse callback
fix py3 dict.keys() 'dict_keys object is not indexable' error
pluralize cli.options.vault_password_file -> vault_password_files
pluralize cli.options.new_vault_password_file -> new_vault_password_files
pluralize cli.options.vault_id -> cli.options.vault_ids
** Add a config option (vault_id_match) to force vault id matching.
With 'vault_id_match=True' and an ansible
vault that provides a vault_id, then decryption will require
that a matching vault_id is required. (via
--vault-id=my_vault_id@password_file, for ex).
In other words, if the config option is true, then only
the vault secrets with matching vault ids are candidates for
decrypting a vault. If option is false (the default), then
all of the provided vault secrets will be selected.
If a user doesn't want all vault secrets to be tried to
decrypt any vault content, they can enable this option.
Note: The vault id used for the match is not encrypted or
cryptographically signed. It is just a label/id/nickname used
for referencing a specific vault secret.
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
* Allow template files to be vaulted
* Make sure to import exceptions we need
* get_real_file can't take bytes, since it looks specifically for string_types
* Now that we aren't using open() we don't need b_source
* Expand playbooks_vault docs to include modules that support vaulted src files
* Add vaulted template test
* Fix vault reading from stdin (avoid realpath() on non-links)
os.path.realpath() is used to find the target of file paths that
are symlinks so vault operations happen directly on the target.
However, in addition to resolving symlinks, realpath() also returns
a full path. when reading from stdin, vault cli uses '-' as a special
file path so VaultEditor() will replace with stdin.
realpath() was expanding '-' with the CWD to something like
'/home/user/playbooks/-' causing errors like:
ERROR! [Errno 2] No such file or directory: u'/home/user/ansible/-'
Fix is to specialcase '-' to not use realpath()
Fixes#23567
* to_text decrypt output when writing to stdout
