adapters can be used together in order to compose complex functionality on top of a provider. adapters can be used together in order to compose complex functionality on top of a provider.
There are currently 5 adapters available: There are currently 2 adapters available:
* `FileSystem.adapters.Compression(provider)` - a default compression adapter that uses [Zlib](https://github.com/imaya/zlib.js) * `FileSystem.adapters.Compression(provider)` - a compression adapter that uses [Zlib](https://github.com/imaya/zlib.js)
* `FileSystem.adapters.Encryption(passphrase, provider)` - a default encryption adapter that uses [AES encryption](http://code.google.com/p/crypto-js/#AES) * `FileSystem.adapters.Encryption(passphrase, provider)` - an encryption adapter that uses [AES encryption](http://code.google.com/p/crypto-js/#AES)
You can also pick from other encryption cipher algorithms:
* `FileSystem.adapters.AES(passphrase, provider)` - extends a provider with [AES encryption](http://code.google.com/p/crypto-js/#AES)
* `FileSystem.adapters.TripleDES(passphrase, provider)` - extends a provider with [TripleDES encryption](http://code.google.com/p/crypto-js/#DES,_Triple_DES)
* `FileSystem.adapters.Rabbit(passphrase, provider)` - extends a provider with [Rabbit encryption](http://code.google.com/p/crypto-js/#Rabbit)
