package md5
import "crypto/md5"
Package md5 implements the MD5 hash algorithm as defined in RFC 1321.
MD5 is cryptographically broken and should not be used for secure applications.
Index ¶
Examples ¶
Constants ¶
const BlockSize = 64
The blocksize of MD5 in bytes.
const Size = 16
The size of an MD5 checksum in bytes.
Functions ¶
func New ¶
New returns a new hash.Hash computing the MD5 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/md5" "fmt" "io" ) func main() { h := md5.New() io.WriteString(h, "The fog is getting thicker!") io.WriteString(h, "And Leon's getting laaarger!") fmt.Printf("%x", h.Sum(nil)) }
Output:
e2c569be17396eca2a2e3c11578123ed
Example (File)¶
Code:play
package main import ( "crypto/md5" "fmt" "io" "log" "os" ) func main() { f, err := os.Open("file.txt") if err != nil { log.Fatal(err) } defer f.Close() h := md5.New() if _, err := io.Copy(h, f); err != nil { log.Fatal(err) } fmt.Printf("%x", h.Sum(nil)) }
func Sum ¶
Sum returns the MD5 checksum of the data.
Example¶
Code:play
package main import ( "crypto/md5" "fmt" ) func main() { data := []byte("These pretzels are making me thirsty.") fmt.Printf("%x", md5.Sum(data)) }
Output:
