crypto
DES,3DES,Aes使用方法：
- DES,3DES,Aes
package main
import (
"encoding/base64"
"fmt"
"github.com/Eric-GreenComb/contrib/crypto"
)
func main() {
// DES 加解密
testDes()
// 3DES加解密
test3Des()
testAes()
}
func testDes() {
key := []byte("sfe023f_")
result, err := crypto.DesEncrypt([]byte("polaris@studygolang"), key)
if err != nil {
panic(err)
}
fmt.Println(base64.StdEncoding.EncodeToString(result))
origData, err := crypto.DesDecrypt(result, key)
if err != nil {
panic(err)
}
fmt.Println(string(origData))
}
func test3Des() {
key := []byte("sfe023f_sefiel#fi32lf3e!")
result, err := crypto.TripleDesEncrypt([]byte("polaris@studygolang"), key)
if err != nil {
panic(err)
}
fmt.Println(base64.StdEncoding.EncodeToString(result))
origData, err := crypto.TripleDesDecrypt(result, key)
if err != nil {
panic(err)
}
fmt.Println(string(origData))
}
func testAes() {
// AES-128。key长度：16, 24, 32 bytes 对应 AES-128, AES-192, AES-256
key := []byte("sfe023f_9fd&fwflsfe023f_9fd&fwfl")
// key := []byte("sfe023f_9fd&fwfl")
result, err := crypto.AesEncrypt([]byte("polaris@studygolang"), key)
if err != nil {
panic(err)
}
fmt.Println(base64.StdEncoding.EncodeToString(result))
origData, err := crypto.AesDecrypt(result, key)
if err != nil {
panic(err)
}
fmt.Println(string(origData))
}
RSA使用方法：
- 生成RSA公私钥文件
package main
import (
"github.com/banerwai/gommon/crypto"
"log"
)
func main() {
var bits int
bits = 2048
if err := crypto.RsaGenKey(bits); err != nil {
log.Fatal("密钥文件生成失败！")
}
log.Println("密钥文件生成成功！")
}
- RsaEncrypt 公钥加密
- RsaDecrypt 私钥解密
package main
import (
"fmt"
"github.com/banerwai/gommon/crypto"
"io/ioutil"
"os"
"time"
)
func main() {
initData := "abcdefghij_klmnopq_"
init := []byte(initData)
data, err := crypto.RsaEncrypt(init, publicKey)
if err != nil {
panic(err)
}
pre := time.Now()
origData, err := crypto.RsaDecrypt(data, privateKey)
if err != nil {
panic(err)
}
now := time.Now()
fmt.Println(now.Sub(pre))
fmt.Println(string(origData))
}
var decrypted string
var privateKey, publicKey []byte
func init() {
var err error
// flag.StringVar(&decrypted, "d", "", "加密过的数据")
// flag.Parse()
publicKey, err = ioutil.ReadFile("public.pem")
if err != nil {
os.Exit(-1)
}
privateKey, err = ioutil.ReadFile("private.pem")
if err != nil {
os.Exit(-1)
}
}
- RsaSign,RsaVerify
package main
import (
"crypto"
"crypto/md5"
"fmt"
banerwaicrypto "github.com/banerwai/gommon/crypto"
"io/ioutil"
"os"
)
func main() {
initData := "abcdefghijklmnopq"
init := []byte(initData)
hashed := md5.Sum(init)
_sign, err := banerwaicrypto.RsaSign(crypto.MD5, hashed[:], privateKey)
init1 := []byte("abcdefghijklmnopq")
hashed1 := md5.Sum(init1)
err = banerwaicrypto.RsaVerify(crypto.MD5, hashed1[:], publicKey, _sign)
if err != nil {
fmt.Println(err.Error())
} else {
fmt.Println("Sign is right")
}
}
var decrypted string
var privateKey, publicKey []byte
func init() {
var err error
// flag.StringVar(&decrypted, "d", "", "加密过的数据")
// flag.Parse()
publicKey, err = ioutil.ReadFile("public.pem")
if err != nil {
os.Exit(-1)
}
privateKey, err = ioutil.ReadFile("private.pem")
if err != nil {
os.Exit(-1)
}
}
