Bcrypt password hashing in Golang (compatible with Node.js)?
Take a look at the bcrypt package from go.crypto (docs are here).
To install it, use
go get golang.org/x/crypto/bcrypt
A blog entry describing the usage of the bcrypt package can be found here. It's from the guy who wrote the package, so it should work ;)
One difference to the node.js library you are using is that the go package doesn't have an (exported) genSalt
function, but it will generate the salt automatically when you call bcrypt.GenerateFromPassword
.
Using the golang.org/x/crypto/bcrypt package, I believe the equivalent would be:
hashedPassword, err := bcrypt.GenerateFromPassword(password, bcrypt.DefaultCost)
Working example:
package main
import (
"golang.org/x/crypto/bcrypt"
"fmt"
)
func main() {
password := []byte("MyDarkSecret")
// Hashing the password with the default cost of 10
hashedPassword, err := bcrypt.GenerateFromPassword(password, bcrypt.DefaultCost)
if err != nil {
panic(err)
}
fmt.Println(string(hashedPassword))
// Comparing the password with the hash
err = bcrypt.CompareHashAndPassword(hashedPassword, password)
fmt.Println(err) // nil means it is a match
}
