gocrypt

gocryptGo实现AES加解密、3DES加解密、RSA加解密（私钥加密公钥解密、公钥加密私钥解密）。

如何使用

1. 首先需要安装Go（需要1.15+版本），然后可以使用下面的Go命令导入gocrypt包。

$ go get github.com/ZYallers/gocrypt

1. 使用案例：

package gocrypt

import (
	"fmt"
	"github.com/ZYallers/gocrypt/aes"
	"github.com/ZYallers/gocrypt/des3"
	"github.com/ZYallers/gocrypt/rsa"
)

const (
	aesKey  = "I98NTHNPezFnbe8iCaSc1xMPAv8ZtTil"
	des3key = "PH5yDbhyPCQmKemfdV7S2T8N"
	pubKey  = `-----BEGIN PUBLIC KEY-----
