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.

# We normalize that to always return unicode on Python2 as that's right most of the
# time. However, this means byte strings can round trip through yaml on Python3 but
# not on Python2. To make this code work the same on Python2 and Python3 (we want
# the Python3 behaviour) we need to change the methods in Ansible to:
# (1) Let byte strings pass through yaml without being converted on Python2
# (2) Convert byte strings to text strings before being given to pyyaml (Without this,
# strings would end up as byte strings most of the time which would mostly be wrong)
# In practice, we mostly read bytes in from files and then pass that to pyyaml, for which
# the present behavior is correct.
# This is a workaround for the current behavior.
