Crypt support is not planned because it's UNIX only.
BCrypt hasher does not allow to set custom salt as in Django. If you encode the same password multiple times you will get different hashes. This limitation comes from golang.org/x/crypto/bcrypt library.
package main
import "github.com/alexandrevicenzi/unchained"
func main() {
hash, err := unchained.MakePassword("my-password", unchained.GetRandomString(12), "default")
if err == nil {
fmt.Println(hash)
} else {
fmt.Printf("Error encoding password: %s\n", err)
}
}package main
import "github.com/alexandrevicenzi/unchained"
func main() {
valid, err := unchained.CheckPassword("admin", "pbkdf2_sha256$24000$JMO9TJawIXB1$5iz40fwwc+QW6lZY+TuNciua3YVMV3GXdgkhXrcvWag=")
if valid {
fmt.Println("Password is valid.")
} else {
if err == nil {
fmt.Println("Password is invalid.")
} else {
fmt.Printf("Error decoding password: %s\n", err)
}
}
