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