Types

type SecureIndexBuilder

type SecureIndexBuilder struct {
	// contains filtered or unexported fields
}

SecureIndexBuilder stores the essential information needed to build the indexes for the documents.

func CreateSecureIndexBuilder

func CreateSecureIndexBuilder(h func() hash.Hash, masterSecret []byte, salts [][]byte, size uint64) *SecureIndexBuilder

CreateSecureIndexBuilder instantiates a `SecureIndexBuilder`. Sets up the hash function, and derives the keys from the master secret and salts by using PBKDF2. Finally, sets up the trapdoor function for the words.

func (*SecureIndexBuilder) BuildSecureIndex

func (sib *SecureIndexBuilder) BuildSecureIndex(docID int, document *os.File, fileLen int) index.SecureIndex

BuildSecureIndex builds the index for `document` with `docID` and an *encrypted* length of `fileLen`.

func (*SecureIndexBuilder) ComputeTrapdoors

func (sib *SecureIndexBuilder) ComputeTrapdoors(word string) [][]byte

ComputeTrapdoors computes the trapdoor values for `word`. This acts as the public getter for the trapdoorFunc field of SecureIndexBUilder.
