Variables

var (
	ErrUnpaddingLength = errors.New("invalid unpadding length")
	ErrNoEncrypt       = errors.New("no encrypt")
)

Functions

func Decrypt

func Decrypt(src, key string) (string, error)

Decrypt 解密.

func Encrypt

func Encrypt(str, key string, cipher Cipher) string

Encrypt 加密.

Example

package main

import (
	"fmt"

	"github.com/xuender/oils/cryptos"
)

func main() {
	key := "key"
	str := cryptos.Encrypt("aaa", key, cryptos.AES)
	fmt.Println(cryptos.Decrypt(str, key))

	str = cryptos.Encrypt("AAA", key, cryptos.DES)
	fmt.Println(cryptos.Decrypt(str, key))

}

Output:

aaa <nil>
AAA <nil>
