Functions ¶

func BitShuffle ¶

func BitShuffle(data []byte, rng cipher.Stream, rev bool) error

func BitSwap ¶

func BitSwap(data []byte, i, j uint64) error

Swaps bits i and j in data. Bit 0 is the first bit of data[0].

func BytesToUInt16 ¶

func BytesToUInt16(data []byte, startIDx, endIDx uint64) (uint16, error)

func CompressBytes ¶

func CompressBytes(src, dst []byte, inputBlockBits, outputBlockBits uint64, inversion16, inversion8 map[uint64]uint64, stream cipher.Stream, tb int) error

func CompressedNBytes ¶

func CompressedNBytes(expandedLen, inputBlockBits, outputBlockBits uint64) uint64

func CompressedNBytes_floor ¶

func CompressedNBytes_floor(expandedLen, inputBlockBits, outputBlockBits uint64) uint64

func ExpandBytes ¶

func ExpandBytes(src, dst []byte, inputBlockBits, outputBlockBits uint64, table16, table8 []uint64, stream cipher.Stream, tb int) error

func ExpandedNBytes ¶

func ExpandedNBytes(srcLen, inputBlockBits, outputBlockBits uint64) uint64

func InvertTable ¶

func InvertTable(vals []uint64) map[uint64]uint64

func PrintBits ¶

func PrintBits(data []byte)

func SampleBiasedString ¶

func SampleBiasedString(numBits uint64, bias float64, stream cipher.Stream) (uint64, error)

Bias of 0.8 means 80% probability of outputting 0

func SampleBiasedStrings ¶
