#passwordHash
An easy to use wrapper around https://godoc.org/golang.org/x/crypto/scrypt
Extracted from a bigger application so this can be used by others if it helps.
This wrapper sets sensible defaults for use with the scrypt package, it also generates a cryptographically secure pseudorandom number for a per password salt using crypto/rand.
#defaults
| Name | Setting | Description |
|---|---|---|
| defaultByteLength | 64 | used salt and password hash length |
| defaultR | 16 | number of rounds |
| defaultN | 16384 | CPU / Memory cost, needs to be power of 2 |
#Usage
package main
import (
"fmt"
"github.com/richardbowden/passwordHash"
)
func main() {
mypass := "mypassword"
fmt.Println("Test password=", mypass)
hashToStore, _ := passwordHash.HashWithDefaults(mypass, mypass)
valid := passwordHash.Validate(mypass, mypass, hashToStore)
fmt.Printf("Password is valid=%v\n", valid)
fmt.Println("Testing invalid password=no against passowrd=mypassword")
valid = passwordHash.Validate("no", hashToStore)
fmt.Printf("Password is not valid=%v\n", valid)
}
