Tencent Kona Provider wraps all the features in KonaCrypto，KonaPKIX and KonaSSL providers into a single provider，so that the applications can just use a single provider name, exactly Kona, to invoke all the features in those three providers。

The provider Kona just wraps the providers KonaCrypto，KonaPKIX and KonaSSL, then please reference theirs READMEs for the usages.

Before using any feature in Kona, it has to load KonaProvider,

Security.addProvider(new KonaProvider());

The above line adds the provider to the last position of the provider list. If necessary, it also can insert the provider at a specific position, like the below,

Security.insertProviderAt(new KonaProvider(), position);

the less the position value is, the higher the privilege is. The minimum value is 1. However, it's not recommended to prioritize this provider. So, Security.addProvider is recommended.

Please note that is no need to load KonaCryptoProvider，KonaPKIXProvider or KonaSSLProvider. Instead, it just needs to put their jars into the classpath. Kona can load all the features in these three providers via reflection.
