Overview ¶
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.

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 ¶
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) ¶
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))
}
