Functions ¶
func BitReverse64 ¶
BitReverse64 returns the bit-reverse value of the input value, within a context of 2^bitLen.
func EqualSliceUint64 ¶
EqualSliceUint64 checks the equality between two uint64 slices.
func EqualSliceUint8 ¶
EqualSliceUint8 checks the equality between two uint8 slices.
func HammingWeight64 ¶
HammingWeight64 returns the hammingweight if the input value.
func IsInSliceUint64 ¶
IsInSliceUint64 checks if x is in slice.
func MaxFloat64 ¶
MaxFloat64 returns the maximum value of the input slice of uint64 values.
Types ¶
type Buffer ¶
type Buffer struct {
// contains filtered or unexported fields
}
Buffer is a simple wrapper around a []byte to facilitate efficient marshaling of lattigo's objects
func (*Buffer) ReadUint64 ¶
ReadUint64 reads an uint64 from the target byte buffer.
func (*Buffer) ReadUint64Slice ¶
ReadUint64Slice reads an uint64 slice from the target byte buffer.
func (*Buffer) ReadUint8Slice ¶
ReadUint8Slice reads an uint8 slice from the target byte buffer.
func (*Buffer) WriteUint64 ¶
WriteUint64 writes an uint64 on the target byte buffer.
func (*Buffer) WriteUint64Slice ¶
WriteUint64Slice writes an uint64 slice on the target byte buffer.
func (*Buffer) WriteUint8 ¶
WriteUint8 writes an uint8 on the target byte buffer.
func (*Buffer) WriteUint8Slice ¶
WriteUint8Slice writes an uint8 slice on the target byte buffer.
type PRNG ¶
type PRNG struct {
// contains filtered or unexported fields
}
PRNG is a structure storing the parameters used to securely and deterministically generate shared sequences of random bytes among different parties using the hash function blake2b. Backward sequence security (given the digest i, compute the digest i-1) is ensured by default, however forward sequence security (given the digest i, compute the digest i+1) is only ensured if the PRNG is given a key.
func (*PRNG) Clock ¶
Clock returns the right 64 bytes digest value of the current PRNG state and reseeds the PRNG with those same 64 bytes. Also increases the clock cycle by 1.
