Управление счетом

In this part, we will learn how to manage a Jami account. This means, how to create a Jami account, modify the basic settings and delete the account. This part will NOT explain what all the settings mean or how we can use the account to do any action like adding a contact.

Что такое учётная запись

In Jami, an account is a X509 certificate chain generally containing 3 certificates:

1. CA (Self-Signed if locally generated or a company)

2. Account (Where the fingerprint of the public key is called the «Jami ID»)

3. Устройство

This allow a company to revoke an account if needed and an account to revoke a device (if one get stolen for example).

API

В cx.ring.Ring.ConfigurationManager:

<method name="addAccount" tp:name-for-bindings="addAccount">
    <tp:docstring>
        Add a new account. When created, the signal <tp:member-ref>accountsChanged</tp:member-ref> is emitted. The clients must then call <tp:member-ref>getAccountList</tp:member-ref> to update their internal data structure.
        <tp:rationale>If no details are specified, the default parameters are used.</tp:rationale>
        <tp:rationale>The core tries to register the account as soon it is created.</tp:rationale>
    </tp:docstring>
    <annotation name="org.qtproject.QtDBus.QtTypeName.In0" value="MapStringString"/>
    <arg type="a{ss}" name="details" direction="in"  tp:type="String_String_Map">
        <tp:docstring>
             The new account settings
        </tp:docstring>
    </arg>
    <arg type="s" name="createdAccountId" direction="out">
        <tp:docstring>
             A new account ID
        </tp:docstring>
    </arg>
</method>

The details can be retrieved from the method getAccountTemplate(type) with type=JAMI or type=SIP. For example, this is the following code used in LRC.

std::string
NewAccountModel::createNewAccount(profile::Type type,
                                  const std::string& displayName,
                                  const std::string& archivePath,
                                  const std::string& password,
                                  const std::string& pin)
{

    MapStringString details = type == profile::Type::SIP?
                              ConfigurationManager::instance().getAccountTemplate("SIP") :
                              ConfigurationManager::instance().getAccountTemplate("JAMI");
    using namespace libjami::Account;
    details[ConfProperties::TYPE] = type == profile::Type::SIP? "SIP" : "JAMI";
    details[ConfProperties::DISPLAYNAME] = displayName.c_str();
    details[ConfProperties::ALIAS] = displayName.c_str();
    details[ConfProperties::UPNP_ENABLED] = "true";
    details[ConfProperties::ARCHIVE_PASSWORD] = password.c_str();
    details[ConfProperties::ARCHIVE_PIN] = pin.c_str();
    details[ConfProperties::ARCHIVE_PATH] = archivePath.c_str();
    QString accountId = ConfigurationManager::instance().addAccount(details);
    return accountId.toStdString();
}

При добавлении нового счета будет выпущен сигнал accountsChanged. Клиент должен обновить свою внутреннюю структуру после этого сигнала с помощью других методов в ConfigurationManager.

Ядро

Основная логика создания нового счета находится в src/ringdht/ringaccount.cpp, в RingAccount::createAccount

Как это работает, с нуля

A Jami account is in fact represented by some files stored in a gzip archive. If a password is provided during the account creation, the archive will be encrypted as following: dht::crypto::aesEncrypt(archive, password) (dht::crypto::aesEncrypt is defined in OpenDHT and use nettle/{aes,gcm}). This is what the archive will contain a big JSON file with:

1. Частный ключ ringAccountKey и цепочка сертификатов ringAccountCert (кодированная в базе64)

2. Создание ключа CA (для самостоятельно подписанных сертификатов) ringCAKey

3. Отзывные устройства ringAccountCRL

4. The ethereum private key ethKey for the device. It’s only used when you register your name on ns.jami.net. Not mandatory.

5. Контакты

6. Настройки счета

Так что давайте создадим его!

Удалить учетную запись

Deleting a Jami account is pretty simple. Because the keys are only on the device, if the keys are deleted… the account is deleted! The only thing outside the device is the username, on the nameserver. To remove this info, it depends how the nameserver work. For example, it’s not possible with https://ns.jami.net

API

В cx.ring.Ring.ConfigurationManager:

<method name="removeAccount" tp:name-for-bindings="removeAccount">
    <tp:docstring>
        Remove an existing account. When removed, the signal <tp:member-ref>accountsChanged</tp:member-ref> is emitted. The clients must then call <tp:member-ref>getAccountList</tp:member-ref> to update their internal data structure.
    </tp:docstring>
    <arg type="s" name="accoundID" direction="in">

             The account to remove, identified by its ID
        </tp:docstring>

После удаления аккаунта будет выпущен сигнал accountsChanged. Клиент должен обновить свою внутреннюю структуру после этого сигнала с помощью других методов в ConfigurationManager.

Основная логика создания нового счета находится в src/manager.cpp, в Manager::removeAccount. Он удаляет файлы счетов и обновляет конфигурацию (dring.yml).

Update the details of an account

API

В cx.ring.Ring.ConfigurationManager:

<method name="setAccountDetails" tp:name-for-bindings="setAccountDetails">
    <tp:docstring>
        Send new account parameters, or account parameters changes, to the core. The hash table is not required to be complete, only the updated parameters may be specified.
        <tp:rationale>Account settings are written to the configuration file when the app properly quits.</tp:rationale>
        <tp:rationale>After calling this method, the core will emit the signal <tp:member-ref>accountDetailsChanged</tp:member-ref> with the updated data. The client must subscribe to this signal and use it to update its internal data structure.</tp:rationale>
    </tp:docstring>
    <arg type="s" name="accountID" direction="in">
    </arg>
    <annotation name="org.qtproject.QtDBus.QtTypeName.In1" value="MapStringString"/>
    <arg type="a{ss}" name="details" direction="in" tp:type="String_String_Map">
    </arg>
</method>

The map can contains a partial update and accountDetailsChanged will be emitted on success. getAccountDetails

Добавить устройство

There is two possibilities to add a device.

Backup archive (Then import from backup)

API

В cx.ring.Ring.ConfigurationManager:

<method name="exportToFile" tp:name-for-bindings="exportToFile">
    <tp:added version="5.1.0"/>
    <tp:docstring>
        Copy the account archive to the path provided in argument.
    </tp:docstring>
    <arg type="s" name="accountID" direction="in">
    </arg>
    <arg type="s" name="destinationPath" direction="in">
    </arg>
    <arg type="s" name="password" direction="in">
    </arg>
    <arg type="b" name="success" direction="out">
        <tp:docstring>
            True if the operation was initialized successfully.
        </tp:docstring>
    </arg>
</method>

Export on DHT

API

В cx.ring.Ring.ConfigurationManager:

<method name="exportOnRing" tp:name-for-bindings="exportOnRing">
    <tp:docstring>
        Export account on the DHT using the given password and generated PIN (returned through exportOnRingEnded signal).
    </tp:docstring>
    <arg type="s" name="accountID" direction="in">
    </arg>
    <arg type="s" name="password" direction="in">
    </arg>
    <arg type="b" name="success" direction="out">
        <tp:docstring>
            True if the operation was initialized successfully. exportOnRingEnded will be trigered on completion.
        </tp:docstring>
    </arg>

Then exportOnRingEnded is emitted.
