Involved Source Files Package md5 implements the MD5 hash algorithm as defined in RFC 1321. MD5 is cryptographically broken and should not be used for secure applications. md5block.go md5block_decl.go md5block_amd64.s
Code Examples 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)) } 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)) } package main import ( "crypto/md5" "fmt" ) func main() { data := []byte("These pretzels are making me thirsty.") fmt.Printf("%x", md5.Sum(data)) }
Package-Level Functions (total 2)
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.
Sum returns the MD5 checksum of the data.
Package-Level Constants (total 2)
The blocksize of MD5 in bytes.
The size of an MD5 checksum in bytes.
