Using gpgme.js

At first, make sure that the environment you want to use gpgme.js in has access and permissions for nativeMessaging, and gpgme-json installed. For details, see the README.

The library itself is started via the {@link init} method. This will test the nativeMessaging connection, and then resolve into an Object offering the top level API:

• [encrypt]{@link GpgME#encrypt}
• [decrypt]{@link GpgME#decrypt}
• [sign]{@link GpgME#sign}
• [verify]{@link GpgME#verify}
• [Keyring]{@link GPGME_Keyring}

gpgmejs.init()
    .then(function(GPGME) {
        // using GPGME
    }, function(error){
        // error handling;
    })

All methods that require communication with nativeMessaging are asynchronous, using Promises. Rejections will be instances of {@link GPGME_Error}.

An exaeption are Keys, which can be initialized in a 'sync' mode, allowing them to be cached and used synchronously until manually refreshed.

Keyring and Keys

The gnupg keys can be accessed via the [Keyring]{@link GPGME_Keyring}.

The Keyring offers the methods for accessing information on all Keys known to gnupg.

Due to security constraints, the javascript-binding currently only offers limited support for secret-Key interaction.

The existence of secret Keys is not secret, and those secret Keys can be used for signing, but Operations that may expose, modify or delete secret Keys are not supported.
