go语言封装的各种对称加密和非对称加密,可以直接使用,包括3重DES,AES的CBC和CTR模式,还有RSA非对称加密

下载到本地可以直接调用

使用方法

```
go get github.com/wumansgy/goEncrypt
```

然后下载到本地可以直接调用,包括了DES的CBC模式的加密解密(虽然DES早就被破解,但是可以参考使用),三重DES的加密解密(可以使用),AES的CBC模式和CTR模式(对称加密中常用的加密算法),非对称加密RSA的加密解密(比较常用的非对称加密算法),椭圆曲线加密算法(后面更新),还有哈希函数sha256,sha512的快速使用(MD5,SHA1已经在2004,2005年被陆续攻破,现在常用sha256和sha512)

## 1.1DES的快速使用

```go
// des
func main() {
msg := "床前明月光,疑是地上霜,举头望明月,低头思故乡"
desSecretKey := "12345678"
base64Text, err := des.DesCbcEncryptBase64([]byte(msg), []byte(desSecretKey), nil)
if err != nil {
fmt.Println(err)
return
}
fmt.Printf("DES模式加密后的base64密文为:\n%s\n", base64Text)
plaintext, err := des.DesCbcDecryptByBase64(base64Text, []byte(desSecretKey), nil)
if err != nil {
fmt.Println(err)
return
}
fmt.Printf("DES模式解密后:\n%s\n", string(plaintext))

## 2.1AES的CBC模式的快速使用

}
```

## 2.2AES的CTR模式的快速使用

```go
func main() {

msg := "床前明月光,疑是地上霜,举头望明月,低头思故乡"
aesSecretKey := "1234567812345678"
base64Text, err := aes.AesCtrEncryptBase64([]byte(msg), []byte(aesSecretKey), nil)

## 3. 非对称加密RSA的快速使用

##### 非对称加密需要先生成一对公钥和私钥,公钥和私钥是成对出现的,公钥加密只能私钥解密,私钥签名只能公钥验签,(加密都是使用私钥加密,公钥解密,数字签名就是使用私钥签名消息的哈希,然后公钥验证签名)

#### 3.1 使用

```go
func main() {
msg := "床前明月光,疑是地上霜,举头望明月,低头思故乡"
rsaBase64Key, err := rsa.GenerateRsaKeyBase64(1024)
if err != nil {
fmt.Println(err)
return
}
base64Text, err := rsa.RsaEncryptToBase64([]byte(msg), rsaBase64Key.PublicKey)
if err != nil {
fmt.Println(err)
return
}
fmt.Printf("rsa加密后的base64密文为:\n%s\n", base64Text)
plaintext, err := rsa.RsaDecryptByBase64(base64Text, rsaBase64Key.PrivateKey)
