package sha1
import "crypto/sha1"
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.
Index ¶
Examples ¶
Constants ¶
const BlockSize = 64
The blocksize of SHA-1 in bytes.
const Size = 20
The size of a SHA-1 checksum in bytes.
Functions ¶
func New ¶
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.
Example¶
Code:play
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)) }
Output:
59 7f 6a 54 00 10 f9 4c 15 d7 18 06 a9 9a 2c 87 10 e7 47 bd
Example (File)¶
Code:play
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)) }
func Sum ¶
Sum returns the SHA-1 checksum of the data.
Example¶
Code:play
package main import ( "crypto/sha1" "fmt" ) func main() { data := []byte("This page intentionally left blank.") fmt.Printf("% x", sha1.Sum(data)) }
Output:
af 06 49 23 bb f2 30 15 96 aa c4 c2 73 ba 32 17 8e bc 4a 96
