Documentation

Overview

Package cryptos 密码.

文本加密/解密，支持AES、DES，多用于配置文件密码加密.

密文格式: 加密方法(base64)

AES(NR501ySw4TYFc0dI8zERfA==)
DES(2lz8gGSpYbA=)

AES安全性较高，DES密文较短.

Example

package main

import (
	"fmt"

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

func main() {
	password := "password"
	txt := cryptos.Encrypt("123", password, cryptos.DES)

	// fmt.Println(txt)
	fmt.Println(cryptos.IsEncrypt(txt))
	fmt.Println(cryptos.Decrypt(txt, password))

}

Output:

true
123 <nil>

Functions

func Decrypt

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

Decrypt 解密.

str, _ := cryptos.Decrypt("AES(NR501ySw4TYFc0dI8zERfA==)", "password")
fmt.Println(str)
// 123

func Encrypt

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

Encrypt 加密.

txt := cryptos.Encrypt("123", "password", cryptos.AES)
fmt.Println(txt)
// AES(NR501ySw4TYFc0dI8zERfA==)

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>

func IsEncrypt

func IsEncrypt(str string) bool

IsEncrypt 是否加密.

func Padding

func Padding(str string, blockSize int) []byte

func UnPadding

func UnPadding(cipherText []byte) (string, error)

Types
