Struct firestore_db_and_auth::credentials::Credentials

pub struct Credentials {
    pub project_id: String,
    pub private_key_id: String,
    pub client_email: String,
    pub client_id: String,
    pub api_key: String,
    pub pub_key: BTreeMap<String, RSAKeyParameters>,
    pub private_key_der: Vec<u8>,
    // some fields omitted
}

Service account credentials

Especially the service account email is required to retrieve the public java web key set (jwks) for verifying Google Firestore tokens.

The api_key is necessary for interacting with the Firestore REST API.

The private key is used for signing java web tokens (jwk). Those can be exchanged into a refresh and access token.

Fields

project_id: String

private_key_id: String

client_email: String

client_id: String

api_key: String

pub_key: BTreeMap<String, RSAKeyParameters>

This is not defined in the json file and computed

private_key_der: Vec<u8>

This is not defined in the json file and computed

Methods

impl Credentials

pub fn public_key(&self, kid: &str) -> Option<&RSAKeyParameters>

Find the key in the set that matches the given key id, if any.

pub fn create_rsa_key_pair(&self) -> Result<RsaKeyPair>

Creates a ring RsaKeyPair out of the private key of this credentials object

pub fn from_file(credential_file: &str) -> Result<Self>

Create a Crentials object of a google-service-account json file.

The corresponding jwks (public keys) for the given service account as well as the "securetoken@system.gserviceaccount.com" are downloaded if you use this method.

pub fn add_jwks_public_keys(&mut self, jwkset: JWKSetDTO)

Add a jwks file to verify Google access tokens

Example:

use firestore_db_and_auth::credentials::Credentials;

let mut c : Credentials = serde_json::from_str(include_str!("../firebase-service-account.json")).unwrap();
c.add_jwks_public_keys(serde_json::from_str(include_str!("../service-account-for-tests.jwks")).unwrap());
c.compute_missing_fields().unwrap();

pub fn compute_missing_fields(&mut self) -> Result<()>

Call this method after deserializing.

If you haven't called [add_jwks_public_keys] before and manually added public keys, this method will download one for your google service account and one for the oauth related securetoken@system.gserviceaccount.com service account.
