Involved Source Files Package sha1 implements the SHA-1 hash algorithm as defined in RFC 3174. SHA-1 is cryptographically broken and should not be used for secure applications. sha1block.go sha1block_amd64.go sha1block_amd64.s
Code Examples package main import ( "crypto/sha1" "fmt" "io" ) func main() { h := sha1.New() io.WriteString(h, "His money is twice tainted:") io.WriteString(h, " 'taint yours and 'taint mine.") fmt.Printf("% x", h.Sum(nil)) } package main import ( "crypto/sha1" "fmt" "io" "log" "os" ) func main() { f, err := os.Open("file.txt") if err != nil { log.Fatal(err) } defer f.Close() h := sha1.New() if _, err := io.Copy(h, f); err != nil { log.Fatal(err) } fmt.Printf("% x", h.Sum(nil)) } package main import ( "crypto/sha1" "fmt" ) func main() { data := []byte("This page intentionally left blank.") fmt.Printf("% x", sha1.Sum(data)) }
Package-Level Functions (total 2)
New returns a new hash.Hash computing the SHA1 checksum. The Hash also implements encoding.BinaryMarshaler and encoding.BinaryUnmarshaler to marshal and unmarshal the internal state of the hash.
Sum returns the SHA-1 checksum of the data.
Package-Level Constants (total 2)
The blocksize of SHA-1 in bytes.
The size of a SHA-1 checksum in bytes.
