In Go, the crypto/md5 package provides a simple way to calculate the MD5 hash of a given string or byte slice.
Here is an example program that demonstrates how to use the crypto/md5 package:
package mainimport ("crypto/md5""encoding/hex""fmt")func main() {data := []byte("hello world")// Calculate the MD5 hashhash := md5.Sum(data)// Convert the hash to a hex stringhexHash := hex.EncodeToString(hash[:])fmt.Println(hexHash) // Output: 5eb63bbbe01eeed093cb22bb8f5acdc3}
In this example, we first define a byte slice containing the data we want to hash ("hello world"). We then call the md5.Sum() function with this data as input. This function returns an array of 16 bytes representing the MD5 hash.
To convert this byte array to a human-readable hex string, we use Go’s built-in hex.EncodeToString() function. Finally, we print out the resulting hex string ("5eb63bbbe01eeed093cb22bb8f5acdc3") using fmt.Println().
