func New() hash.Hash64

New creates a new SeaHash hash.Hash64

Example ¶

// hash some bytes
h := New()
h.Write([]byte("to be or not to be"))
hash := h.Sum64()
fmt.Printf("%x", hash)

Output:

func Sum(b []byte) []byte

Sum is a convenience method that returns the checksum of the byte slice

Example ¶

// hash some bytes
hash := Sum([]byte("to be or not to be"))
fmt.Printf("%x", hash)

Output:

75e54a6f823a991b

func Sum64(b []byte) uint64

Sum64 is a convenience method that returns uint64 checksum of the byte slice

Example ¶

// hash some bytes
fmt.Printf("%x", Sum64([]byte("to be or not to be")))

Output:
