Functions ¶
func Check ¶
Check compares the given crypt(3) DES 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/des"
)
func main() {
hash := "eNBO0nZMf3rWM"
fmt.Println(des.Check(hash, "password"))
fmt.Println(des.Check(hash, "test"))
}
Output: <nil> hash and password mismatch
func Key ¶
Key returns a DES key derived from the password and salt.
Example ¶
package main
import (
"fmt"
"github.com/sergeymakinen/go-crypt/des"
"github.com/sergeymakinen/go-crypt/hash"
)
func main() {
salt, _ := des.Salt("eNBO0nZMf3rWM")
fmt.Println(string(salt))
key, _ := des.Key([]byte("password"), salt)
fmt.Println(hash.BigEndianEncoding.EncodeToString(key))
}
Output: eN BO0nZMf3rWM
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 InvalidSaltError ¶
type InvalidSaltError byte
InvalidSaltError values describe errors resulting from an invalid character in a hash string.
func (InvalidSaltError) Error ¶
func (e InvalidSaltError) Error() string
type InvalidSaltLengthError ¶
type InvalidSaltLengthError int
InvalidSaltLengthError values describe errors resulting from an invalid length of a salt.
func (InvalidSaltLengthError) Error ¶
func (e InvalidSaltLengthError) 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
