blake2s.BlockSize

// The blocksize of BLAKE2s in bytes. const BlockSize = 64

blake2s.OutputLengthUnknown

// OutputLengthUnknown can be used as the size argument to NewXOF to indicate // the length of the output is not known in advance. const OutputLengthUnknown = 0

blake2s.Size

// The hash size of BLAKE2s-256 in bytes. const Size = 32

blake2s.Size128

// The hash size of BLAKE2s-128 in bytes. const Size128 = 16

blake2s.XOF

// XOF defines the interface to hash functions that // support arbitrary-length output. type XOF interface { // Write absorbs more data into the hash's state. It panics if called // after Read. io.Writer // Read reads more output from the hash. It returns io.EOF if the limit // has been reached. io.Reader // Clone returns a copy of the XOF in its current state. Clone() XOF // Reset resets the XOF to its initial state. Reset() }

blake2s.New128

// New128 returns a new hash.Hash computing the BLAKE2s-128 checksum given a // non-empty key. Note that a 128-bit digest is too small to be secure as a // cryptographic hash and should only be used as a MAC, thus the key argument // is not optional. func New128(key []byte) (hash.Hash, error)

blake2s.New256

// New256 returns a new hash.Hash computing the BLAKE2s-256 checksum. A non-nil // key turns the hash into a MAC. The key must between zero and 32 bytes long. // When the key is nil, the returned hash.Hash implements BinaryMarshaler // and BinaryUnmarshaler for state (de)serialization as documented by hash.Hash. func New256(key []byte) (hash.Hash, error)

blake2s.NewXOF

// NewXOF creates a new variable-output-length hash. The hash either produce a // known number of bytes (1 <= size < 65535), or an unknown number of bytes // (size == OutputLengthUnknown). In the latter case, an absolute limit of // 128GiB applies. // // A non-nil key turns the hash into a MAC. The key must between // zero and 32 bytes long. func NewXOF(size uint16, key []byte) (XOF, error)

blake2s.Sum256

// Sum256 returns the BLAKE2s-256 checksum of the data. func Sum256(data []byte) [Size]byte
