Apache Cordova Cryptography Plugin
This project implements a cryptography plugin for the Cross-Platform Framework Apache Cordova. The plugin is currently available for Android only. The plugin implements the Web Crypto API. Therefore, cryptographic methods can be invoked using the interface provided by the Web Crypto API. The cryptographic methods are implemented natively and cryptographic keys are stored using the on-device key storage facilities. As many Android devices use a KeyStore backed by a Secure Element, this cryptography plugin provides protection against software attacks on the key material.
During implementation we have focused on cryptographic methods, that require the storage of key material. Therefore, we do not provide implementations of hashing algorithms, as hash algorithms provided by the user agent can be used safely.
We have introduced so-called crypto providers. Thus multiple implementations of the Web Crypto API can be instantiated and used within a web application.
Getting the crypto provider implemented within the Apache Cordova Plugin:
var cordovaCryptoApi = window.getCryptoProviderByName("cordova-iaik");
Getting the crypto provider implemented within the user agent:
var w3cCryptoApi = window.getCryptoProviderByName("w3c");.
importKey(...) the additional attribute “id” has to be added to the algorithm dictionary. The README.txt included within the cordova-crypto-plugin.zip file provides additional documentation on how to use the plugin.
The following table provides an overview of implemented cryptographic methods:
