Functions ¶

func BytesHash ¶

func BytesHash(bs []byte, algo crypto.Hash) string

func BytesSha1 ¶

func BytesSha1(bs []byte) string

func FileHash ¶

func FileHash(path string, algo crypto.Hash) (string, error)

func FileSha1 ¶

func FileSha1(path string) (string, error)

func Hash ¶

func Hash(reader io.Reader, algo crypto.Hash) (string, error)

func OtherPlatformHash ¶

func OtherPlatformHash(reader io.Reader, algo crypto.Hash) (string, error)

OtherPlatformHash calculates the hash of the provided io.Reader contents, after replacing the line endings to the other platform type. if the line endings are CRLF, they will be switched to LF if the line endings are LF, they will be switched to CRLF

func OtherPlatformSha1 ¶

func OtherPlatformSha1(reader io.Reader) (string, error)

func StringHash ¶

func StringHash(str string, algo crypto.Hash) string

func StringSha1 ¶

func StringSha1(str string) string

Types ¶

type SuperHash ¶

type SuperHash struct {
	// FullHash contains a hash of the whole file
	FullHash string

	// MosSigBitsHash contains a hash of the first bits of the file. Amount of bits determined by bucket size.
	MostSigBitsHash string

	// LeastSigBitsHash contains a hash of the last bits of the file. Amount of bits determined by bucket size.
	LeastSigBitsHash string
	// contains filtered or unexported fields
}

SuperHash contains various hashes of a source file. All hashes are performed after stripping away all whitespace from the file

func CalculateSuperHash ¶

func CalculateSuperHash(rs io.ReadSeeker, algo crypto.Hash) (h *SuperHash, err error)

CalculateSuperHash calculates the super hash of the provided reader, with the provided hash algorithm

func CalculateSuperSha1 ¶

func CalculateSuperSha1(rs io.ReadSeeker) (*SuperHash, error)
