func Checksum

func Checksum(reader io.Reader) (string, error)

Checksum reads from reader and returns the hash of the bytes as a hex string. Checksum buffers from reader internally.

func ChecksumBuffer

func ChecksumBuffer(reader io.Reader, buffer []byte) (string, error)

ChecksumBuffer reads from reader and returns the hash of the bytes as a hex string. ChecksumBuffer uses the buffer argument to buffer I/O from the reader to the hasher. If the buffer passed is zero-length, this function will panic.
