func (*Bucket) GetFileEncryptionKeyForPath 

func (b *Bucket) GetFileEncryptionKeyForPath(pth string) ([]byte, error)

GetFileEncryptionKeyForPath returns the encryption key for path. Version 0 buckets use the link key for all paths. Version 1 buckets use a different key defined in path metadata.

func (*Bucket) GetFileEncryptionKeysForPrefix 

func (b *Bucket) GetFileEncryptionKeysForPrefix(pre string) (map[string][]byte, error)

GetFileEncryptionKeysForPrefix returns a map of keys for every path under prefix.

func (*Bucket) GetLinkEncryptionKey 

func (b *Bucket) GetLinkEncryptionKey() []byte

func (*Bucket) GetMetadataForPath 

func (b *Bucket) GetMetadataForPath(pth string, requireKey bool) (md Metadata, at string, ok bool)

GetMetadataForPath returns metadata for path. The returned metadata could be from an exact path match or the nearest parent, i.e., path was added as part of a folder. If requireKey is true, metadata w/o a key is ignored and the search continues toward root.

func (*Bucket) IsPrivate 

func (b *Bucket) IsPrivate() bool
