Bucket is a local-first object storage and synchronization model built on ThreadDB, IPFS, and Filecoin. A bucket represents a dynamic Unixfs directory with auto-updating IPNS resolution, website rendering, and Filecoin archivng.

Private buckets are fully encrypted using AES-CTR + AES-512 HMAC (see https://github.com/textileio/dcrypto for more). Both Unixfs node metadata (size, links, etc.) and node data (files) are obfuscated by encryption. The AES and HMAC keys used for bucket encryption are stored in the ThreadDB collection instance. This setup allows for bucket access to inherit from thread ACL rules.

Additionally, files can be further protected by password-based encryption before they are added to the bucket. See EncryptLocalPath and DecryptLocalPath for more.
