Adrian Likins	6e737c8cb6	Fix 'New Vault password' on vault 'edit' (#35923) ... * Fix 'New Vault password' on vault 'edit' ffe0ddea96 introduce a change on 'ansible-vault edit' that tried to check for --encrypt-vault-id in that mode. But '--encrypt-vault-id' is not intended for 'edit' since the 'edit' should always reuse the vault secret that was used to decrypt the text. Change cli to not check for --encrypt-vault-id on 'edit'. VaultLib.decrypt_and_get_vault_id() was change to return the vault secret used to decrypt (in addition to vault_id and the plaintext). VaultEditor.edit_file() will now use 'vault_secret_used' as returned from decrypt_and_get_vault_id() so that an edited file always gets reencrypted with the same secret, regardless of any vault id configuration or cli options.

Michael Scherer	060001b08d	Remove deprecated code (#34828) ... * Remove compat code for to_unicode, to_str and to_bytes Code was marked as deprecated and to be removed after 2.4 * Remove is_encrypted and is_encrypted_file Code was marked as deprecated after 2.4 release.	7 years ago
Adrian Likins	fc180a378a	Support using vault password files that are themselves vault encrypted (#27668) ... Extract vault related bits of DataLoader._get_file_contents to DataLoader._decrypt_if_vault_data When loading vault password files, detect if they are vault encrypted, and if so, try to decrypt with any already known vault secrets. This implements the 'Allow vault password files to be vault encrypted' (#31002) feature card from the 2.5.0 project at https://github.com/ansible/ansible/projects/9 Fixes #31002	7 years ago

Adrian Likins	9c58827410	Better handling of malformed vault data envelope (#32515) ... * Better handling of malformed vault data envelope If an embedded vaulted variable ('!vault' in yaml) had an invalid format, it would eventually cause an error for seemingly unrelated reasons. "Invalid" meaning not valid hexlify (extra chars, non-hex chars, etc). For ex, if a host_vars file had invalid vault format variables, on py2, it would cause an error like: 'ansible.vars.hostvars.HostVars object' has no attribute u'broken.example.com' Depending on where the invalid vault is, it could also cause "VARIABLE IS NOT DEFINED!". The behavior can also change if ansible-playbook is py2 or py3. Root cause is errors from binascii.unhexlify() not being handled consistently. Fix is to add a AnsibleVaultFormatError exception and raise it on any unhexlify() errors and to handle it properly elsewhere. Add a _unhexlify() that try/excepts around a binascii.unhexlify() and raises an AnsibleVaultFormatError on invalid vault data. This is so the same exception type is always raised for this case. Previous it was different between py2 and py3. binascii.unhexlify() raises a binascii.Error if the hexlified blobs in a vault data blob are invalid. On py2, binascii.Error is a subclass of Exception. On py3, binascii.Error is a subclass of TypeError When decrypting content of vault encrypted variables, if a binascii.Error is raised it propagates up to playbook.base.Base.post_validate(). post_validate() handles exceptions for TypeErrors but not for base Exception subclasses (like py2 binascii.Error). * Add a display.warning on vault format errors * Unit tests for _unhexlify, parse_vaulttext* * Add intg test cases for invalid vault formats Fixes #28038	7 years ago
Adrian Likins	297dfb1d50	Vault secrets script client inc new 'keyring' client (#27669) ... This adds a new type of vault-password script (a 'client') that takes advantage of and enhances the multiple vault password support. If a vault password script basename ends with the name '-client', consider it a vault password script client. A vault password script 'client' just means that the script will take a '--vault-id' command line arg. The previous vault password script (as invoked by --vault-password-file pointing to an executable) takes no args and returns the password on stdout. But it doesnt know anything about --vault-id or multiple vault passwords. The new 'protocol' of the vault password script takes a cli arg ('--vault-id') so that it can lookup that specific vault-id and return it's password. Since existing vault password scripts don't know the new 'protocol', a way to distinguish password scripts that do understand the protocol was needed. The convention now is to consider password scripts that are named like 'something-client.py' (and executable) to be vault password client scripts. The new client scripts get invoked with the '--vault-id' they were requested for. An example: ansible-playbook --vault-id my_vault_id@contrib/vault/vault-keyring-client.py some_playbook.yml That will cause the 'contrib/vault/vault-keyring-client.py' script to be invoked as: contrib/vault/vault-keyring-client.py --vault-id my_vault_id The previous vault-keyring.py password script was extended to become vault-keyring-client.py. It uses the python 'keyring' module to request secrets from various backends. The plain 'vault-keyring.py' script would determine which key id and keyring name to use based on values that had to be set in ansible.cfg. So it was also limited to one keyring name. The new vault-keyring-client.py will request the secret for the vault id provided via the '--vault-id' option. The script can be used without config and can be used for multiple keyring ids (and keyrings). On success, a vault password client script will print the password to stdout and exit with a return code of 0. If the 'client' script can't find a secret for the --vault-id, the script will exit with return code of 2 and print an error to stderr.	7 years ago
Adrian Likins	e287af1ac8	Vault secrets empty password (#28186) ... * Better handling of empty/invalid passwords empty password files are global error and cause an exit. A warning is also emitted with more detail. ie, if any of the password/secret sources provide a bogus password (ie, empty) or fail (exception, ctrl-d, EOFError), we stop at the first error and exit. This makes behavior when entering empty password at prompt match 2.3 (ie, an error)	7 years ago

Adrian Likins	2b0a7338d4	Handle win style CRLF newlines in vault text (#27590) ... When parsing a vaulttext blob, use .splitlines() instead of split(b'\n') to handle \n newlines and windows style \r\n (CRLF) new lines. The vaulttext enevelope at this point is just the header line and a hexlify()'ed blob, so CRLF is a valid newline here. Fixes #22914	7 years ago
Adrian Likins	934b645191	Support multiple vault passwords (#22756) ... 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.	7 years ago
Toshio Kuratomi	e238ae999b	Cyptography pr 20566 rebase (#25560) ... 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	8 years ago

Toshio Kuratomi	2fff690caa	Update module_utils.six to latest (#22855) ... * Update module_utils.six to latest We've been held back on the version of six we could use on the module side to 1.4.x because of python-2.4 compatibility. Now that our minimum is Python-2.6, we can update to the latest version of six in module_utils and get rid of the second copy in lib/ansible/compat.	8 years ago
Toshio Kuratomi	e70066a6f7	Many Cleanups to vault ... * Make is_encrypted_file handle both files opened in text and binary mode On python3, by default files are opened in text mode. Since we know the encoding of vault files (and especially the header which is the first set of bytes) we can decide whether the file is an encrypted vault file in either case. * Fix is_encrypted_file not resetting the file position * Update is_encrypted_file to check that all the data in the file is ascii * For is_encrypted_file(), add start_pos and count parameters This allows callers to specify reading vaulttext from the middle of a file if necessary. * Combine VaultLib.encrypt() and VaultLib.encrypt_bytestring() * Change vault's is_encrypted() to take either text or byte strings and to return False if any part of the data is non-ascii. * Remove unnecessary use of six.b * Vault Cipher: mark a few methods as private. * VaultAES256._is_equal throws a TypeError if given non byte strings * Make VaultAES256 methods that don't need self staticmethods and classmethods * Mark VaultAES and is_encrypted as deprecated * Get rid of VaultFile (unused and feature implemented in a different way) * Normalize variable and parameter names on plaintext, ciphertext, vaulttext * Normalize variable and parameter names on "b_" prefix when dealing with bytes * Test changes: * Remove redundant tests( both checking the same byte string) * Fix use of format string without format operator * Enable vault editor tests on python3 * Initialize the vault_cipher for VaultAES256 testing in setUp() * Make assertTrue and assertFalse take the actual method calls for better error messages. * Test that non-ascii byte strings compare correctly. * Test that unicode strings and ints raise TypeError * Test-specific: * Removed test_methods_exist(). We only have one VaultLib so the implementation is the assurance that the methods exist. (Can use an abc for this if it changes). * Add tests for both byte string and text string input where the API takes either. * Convert "assert" to unittest assert functions or add a custom message where that will make failures easier to debug. * Move instantiating the VaultLib into setUp().	8 years ago
Toshio Kuratomi	4ed88512e4	Move uses of to_bytes, to_text, to_native to use the module_utils version (#17423) ... We couldn't copy to_unicode, to_bytes, to_str into module_utils because of licensing. So once created it we had two sets of functions that did the same things but had different implementations. To remedy that, this change removes the ansible.utils.unicode versions of those functions.	8 years ago
Adrian Likins	e396d5d508	Implement vault encrypted yaml variables. (#16274) ... Make !vault-encrypted create a AnsibleVaultUnicode yaml object that can be used as a regular string object. This allows a playbook to include a encrypted vault blob for the value of a yaml variable. A 'secret_password' variable can have it's value encrypted instead of having to vault encrypt an entire vars file. Add __ENCRYPTED__ to the vault yaml types so template.Template can treat it similar to __UNSAFE__ flags. vault.VaultLib api changes: - Split VaultLib.encrypt to encrypt and encrypt_bytestring - VaultLib.encrypt() previously accepted the plaintext data as either a byte string or a unicode string. Doing the right thing based on the input type would fail on py3 if given a arg of type 'bytes'. To simplify the API, vaultlib.encrypt() now assumes input plaintext is a py2 unicode or py3 str. It will encode to utf-8 then call the new encrypt_bytestring(). The new methods are less ambiguous. - moved VaultLib.is_encrypted logic to vault module scope and split to is_encrypted() and is_encrypted_file(). Add a test/unit/mock/yaml_helper.py It has some helpers for testing parsing/yaml Integration tests added as roles test_vault and test_vault_embedded	8 years ago

Abhijit Menon-Sen	4f3a98eff6	Update Vault tests to make sure AES decryption works ... Note that this test was broken in devel because it was really just duplicating the AES256 test because setting v.cipher_name to 'AES' no longer selected AES after it was de-write-whitelisted. Now that we've removed the VaultAES encryption code, we embed static output from an earlier version and test that we can decrypt it.	9 years ago
