[Aerogear-users] AeroGear Crypto API on iOS with AES-GCM

[Erik Jan de Wit]

I did the plugin and I'm not sure about all the Implementation
details, but on iOS the plugin calls this method
https://github.com/aerogear/aerogear-crypto-ios/blob/master/crypto-sdk/AGCryptoBox.m#L40
so no GCM it seems this is only done on android. On iOS we have
created a wrapper around NaCI and it seems that is able to do GCM, but
we don't use it there because it's not the most common algorithm.
