Certification level

This repo is a Community level project. It's a community contributed project that is not reviewed or supported by CyberArk. For more detailed information on our certification levels, see our community guidelines .

Requirements

This project requires a working Conjur server

It officially requires python 3.10 and above but can run with lower versions compiled with openssl 1.1.1

How to use the client

Prerequisites

It is assumed that Conjur (OSS or Enterprise) have already been installed in the environment and running in the background. If you haven't done so, follow these instructions for installation of the OSS and these for installation of Enterprise.

Once Conjur is running in the background, you are ready to start setting up your python app to work with our Conjur python API!

Installation

The SDK can be installed via PyPI. Note that the SDK is a Community level project meaning that the SDK is subject to alterations that may result in breaking change.

pip3 install conjur

To avoid unanticipated breaking changes, make sure that you stay up-to-date on our latest releases and review the project's CHANGELOG.md.

Alternatively, you can install the library from the source. Note that this will install the latest work from the cloned source and not necessarily an official release.

If you wish to install the library from the source clone the project and run:

pip3 install .

Configuring the client

Define connection parameters

In order to login to conjur you need to have 5 parameters known from advance.

conjur_url = "https://my_conjur.com"
account = "my_account"
username = "user1"
password = "SomeStr@ngPassword!1"
ssl_verification_mode = SslVerificationMode.TRUST_STORE

Define ConjurConnectionInfo

ConjurConnectionInfo is a data class containing all the non-credentials connection details.

connection_info = ConjurConnectionInfo(conjur_url=conjur_url,account=account,cert_file=None,service_id="ldap-service-id", proxy_params=None)

• conjur_url - url of conjur server
• account - the account which we want to connect to
• cert_file - a path to conjur rootCA file. we need it if we initialize the client in SslVerificationMode.SELF_SIGN or SslVerificationMode.CA_BUNDLE mode
• service_id - a service id for the Conjur authenticator. Required when using the ldap authenticator (see below) but not when using the default authn authenticator.
• proxy_params - parameters for proxy connection. see ProxyParams class for more details - Optional

Create credentials provider

The client uses credentials provider in order to get the connection credentials before making api command. This approach allow to keep the credentials in a safe location and provide it to the client on demand.

We provide the user with CredentialsProviderInterface which can be implemented the way the user see as best fit (keyring usage for example)

We also provide the user with a simple implementation of such provider called SimpleCredentialsProvider. Example of creating such provider + storing credentials:

credentials = CredentialsData(username=username, password=password, machine=conjur_url)
credentials_provider = SimpleCredentialsProvider()
credentials_provider.save(credentials)
del credentials

Create authentication strategy

The client also uses an authentication strategy in order to authenticate to conjur. This approach allows us to implement different authentication strategies (e.g. authn, authn-ldap, authn-k8s) and to keep the authentication logic separate from the client implementation.

We provide the AuthnAuthenticationStrategy for the default Conjur authenticator. Example use:

authn_provider = AuthnAuthenticationStrategy(credentials_provider)

We also provide the LdapAuthenticationStrategy for the ldap authenticator, and OidcAuthenticationStrategy for the OIDC authenticator. Example use:

authn_provider = LdapAuthenticationStrategy(credentials_provider)
authn_provider = OidcAuthenticationStrategy(credentials_provider)

When using these strategies, make sure connection_info has a service_id specified.

Creating the client and use it

Now that we have created connection_info and authn_provider, we can create our client:

client = Client(connection_info,
                authn_strategy=authn_provider,
                ssl_verification_mode=ssl_verification_mode)

• ssl_verification_mode = SslVerificationMode enum that states what is the certificate verification technique we will use when making the api request

After creating the client we can login to conjur and start using it. Example of usage:

client.login() # login to conjur and return the api_key
client.list() # get list of all conjur resources that the user authorize to read

Supported Client methods

get(variable_id)

Gets a variable value based on its ID. Variable is binary data that should be decoded to your system's encoding. For example: get(variable_id).decode('utf-8').

get_many(variable_id[,variable_id...])

Gets multiple variable values based on their IDs. Variables are returned in a dictionary that maps the variable name to its value.

set(variable_id, value)

Sets a variable to a specific value based on its ID.

Note: Policy to create the variable must have already been loaded, otherwise you will get a 404 error during invocation.

load_policy_file(policy_name, policy_file)

Applies a file-based YAML to a named policy. This method only supports additive changes. Result is a dictionary object constructed from the returned JSON data.

replace_policy_file(policy_name, policy_file)

Replaces a named policy with one from the provided file. This is usually a destructive invocation. Result is a dictionary object constructed from the returned JSON data.

update_policy_file(policy_name, policy_file)

Modifies an existing Conjur policy. Data may be explicitly deleted using the !delete, !revoke, and !deny statements. Unlike "replace" mode, no data is ever implicitly deleted. Result is a dictionary object constructed from the returned JSON data.

list(list_constraints)

Returns a list of all available resources for the current account.

The 'list constraints' parameter is optional and should be provided as a dictionary.

For example: client.list({'kind': 'user', 'inspect': True})

List constraints	Explanation
kind	Filter resources by specified kind (user, host, layer, group, policy, variable, or webservice)
limit	Limit list of resources to specified number
offset	Skip specified number of resources
role	Retrieve list of resources that specified role is entitled to see (must specify role's full ID)
search	Search for resources based on specified query
inspect	List the metadata for resources

check_privilege(kind, resource_id, privilege, role_id)

Checks for a privilege on a resource based on its kind, resource ID, and an optional role ID. Returns a boolean.

get_resource(kind, resource_id)

Gets a resource based on its kind and ID. Resource is json data that contains metadata about the resource.

resource_exists(kind, resource_id)

Check the existence of a resource based on its kind and ID. Returns a boolean.

get_role(kind, role_id)

Gets a role based on its kind and ID. Role is json data that contains metadata about the role.

role_exists(kind, resource_id)

Check the existence of a role based on its kind and ID. Returns a boolean.

role_memberships(kind, role_id)

Gets a role's memberships based on its kind and ID. Returns a list of all roles recursively inherited by this role.

def list_permitted_roles(list_permitted_roles_data: ListPermittedRolesData)

Lists the roles which have the named permission on a resource.

def list_members_of_role(data: ListMembersOfData)

Lists the resources which are members of the given resource.

def create_token(create_token_data: CreateTokenData)

Creates Host Factory tokens for creating hosts

def create_host(create_host_data: CreateHostData)

Uses Host Factory token to create host

def revoke_token(token: str)

Revokes the given Host Factory token

rotate_other_api_key(resource: Resource)

Rotates another entity's API key and returns it as a string.

Note: resource is of type Resource which should have type (user / host) and name attributes.

rotate_personal_api_key(logged_in_user, current_password)

Rotates the personal API key of the logged-in user and returns it as a string.

change_personal_password(logged_in_user, current_password, new_password)

Updates the current, logged-in user's password with the password parameter provided.

Note: the new password must meet the Conjur password complexity constraints. It must contain at least 12 characters: 2 uppercase, 2 lowercase, 1 digit, 1 special character.

whoami()

Note: This method requires Conjur v1.9+

Returns a Python dictionary of information about the client making an API request (such as its IP address, user, account, token expiration date, etc).

set_authenticator_state(authenticator_id, enabled)

Allows enabling and disabling an authenticator.

Note: This functionality relies on an endpoint in Conjur which is part of an early implementation of support for enabling Conjur authenticators via the API, and is currently available at the Community (or early alpha) level. This endpoint is still subject to breaking changes in the future.

authenticate()

Performs an authentication with Conjur, based on the authentication strategy and credentials provider there were given to the client. This method is not required, it will also be done implicitly and automatically when session with Conjur needs to be refreshed.
