You can use the crypto/md5 [docs] package in Go to perform MD5 encoding on a string. We have an example function below, it will take your string and write it as a hash. Then convert that binary back into a hexadecimal string using Sprintf.
Note: There are more modern approaches than md5 these days - and it isn’t recommended for many things, but definitely not password hashing.
Here’s an example of how to use it:
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 | package main import ( "crypto/md5" "fmt" ) func main() { input := "welcome to gophercoding.com" output := md5Encode(input) fmt.Println(input, "=", output) } // md5Encode will take a string and encode it as md5. func md5Encode(input string) string { // Create a new hash & write input string hash := md5.New() _, _ = hash.Write([]byte(input)) // Get the resulting encoded byte slice md5 := hash.Sum(nil) // Convert the encoded byte slice to a string return fmt.Sprintf("%x", md5) } |
