Functions ¶
func Check ¶
Check compares the given crypt(3) NT Hash hash with a new hash derived from the password. Returns nil on success, or an error on failure.
Example ¶
package main
import (
"fmt"
"github.com/sergeymakinen/go-crypt/nthash"
)
func main() {
hash := "$3$$8846f7eaee8fb117ad06bdd830b7586c"
fmt.Println(nthash.Check(hash, "password"))
fmt.Println(nthash.Check(hash, "test"))
}
Output: <nil> hash and password mismatch
func Key ¶
Key returns a NT Hash key derived from the password and salt.
Example ¶
package main
import (
"encoding/binary"
"encoding/hex"
"fmt"
"unicode/utf16"
"github.com/sergeymakinen/go-crypt/nthash"
)
func main() {
// UTF-8 to UTF-16 LE
a := utf16.Encode([]rune("password"))
b := make([]byte, len(a)*2)
for i, r := range a {
binary.LittleEndian.PutUint16(b[i*2:], r)
}
key, _ := nthash.Key(b)
fmt.Println(hex.EncodeToString(key))
}
Output: 8846f7eaee8fb117ad06bdd830b7586c
Types ¶
type InvalidPasswordLengthError ¶
type InvalidPasswordLengthError int
InvalidPasswordLengthError values describe errors resulting from an invalid length of a password.
func (InvalidPasswordLengthError) Error ¶
func (e InvalidPasswordLengthError) Error() string
type UnsupportedPrefixError ¶
type UnsupportedPrefixError string
UnsupportedPrefixError values describe errors resulting from an unsupported prefix string.
func (UnsupportedPrefixError) Error ¶
func (e UnsupportedPrefixError) Error() string
