golangHow to generate sha256 hash from string
package main
import (
"fmt"
"crypto/sha256"
)
func main() {
str := "Hi all!"
h := sha256.New()
h.Write([]byte(str))
hash := h.Sum(nil)
fmt.Printf("%x", hash)
}ctrl + cpackage maindefault package declaration | "hash/sha256"package to calculate SHA256 hashes |
"Hi all!"sample string to hash | sha256.New()new shad56 hasher |
h.Write([]byte(str))pass our string to hasher | h.Sum(nil)calculate and return hash |
Usage example
package main
import (
"fmt"
"crypto/sha256"
)
func main() {
str := "Hi all!"
h := sha256.New()
h.Write([]byte(str))
hash := h.Sum(nil)
fmt.Printf("%x", hash)
}output
