Package 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.
Constants
The blocksize of MD5 in bytes.
const BlockSize = 64
The size of an MD5 checksum in bytes.
const Size = 16
func New() hash.Hash
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:
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:
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
¶
1.2
func Sum(data []byte) [Size]byte
Sum returns the MD5 checksum of the data.
Example
Code:
data := []byte("These pretzels are making me thirsty.")
fmt.Printf("%x", md5.Sum(data))
Output:
