## Installation
The only requirement is the [Go Programming Language](https://golang.org/dl/)
```
go get -u github.com/go-think/openssl
```
## Usage
### AES
The length of the key can be 16/24/32 characters (128/192/256 bits)
AES-ECB:
```go
src := []byte("123456")
key := []byte("1234567890123456")
dst , _ := openssl.AesECBEncrypt(src, key, openssl.PKCS7_PADDING)
fmt.Printf(base64.StdEncoding.EncodeToString(dst)) // yXVUkR45PFz0UfpbDB8/ew==
dst , _ = openssl.AesECBDecrypt(dst, key, openssl.PKCS7_PADDING)
fmt.Println(string(dst)) // 123456
```
AES-CBC:
```go
src := []byte("123456")
key := []byte("1234567890123456")
iv := []byte("1234567890123456")
dst , _ := openssl.AesCBCEncrypt(src, key, iv, openssl.PKCS7_PADDING)
fmt.Println(base64.StdEncoding.EncodeToString(dst)) // 1jdzWuniG6UMtoa3T6uNLA==
dst , _ = openssl.AesCBCDecrypt(dst, key, iv, openssl.PKCS7_PADDING)
fmt.Println(string(dst)) // 123456
```
### DES
The length of the key must be 8 characters (64 bits).
DES-ECB:
```go
openssl.DesECBEncrypt(src, key, openssl.PKCS7_PADDING)
openssl.DesECBDecrypt(src, key, openssl.PKCS7_PADDING)
```
DES-CBC:
```go
openssl.DesCBCEncrypt(src, key, iv, openssl.PKCS7_PADDING)
openssl.DesCBCDecrypt(src, key, iv, openssl.PKCS7_PADDING)
```
### 3DES
The length of the key must be 24 characters (192 bits).
3DES-ECB:
```go
openssl.Des3ECBEncrypt(src, key, openssl.PKCS7_PADDING)
openssl.Des3ECBDecrypt(src, key, openssl.PKCS7_PADDING)
```
3DES-CBC:
```go
openssl.Des3CBCEncrypt(src, key, iv, openssl.PKCS7_PADDING)
openssl.Des3CBCDecrypt(src, key, iv, openssl.PKCS7_PADDING)
```
### RSA
```go
openssl.RSAGenerateKey(bits int, out io.Writer)
openssl.RSAGeneratePublicKey(priKey []byte, out io.Writer)
openssl.RSAEncrypt(src, pubKey []byte) ([]byte, error)
openssl.RSADecrypt(src, priKey []byte) ([]byte, error)
openssl.RSASign(src []byte, priKey []byte, hash crypto.Hash) ([]byte, error)
openssl.RSAVerify(src, sign, pubKey []byte, hash crypto.Hash) error
```
### HMAC-SHA
```
// Sha1 Calculate the sha1 hash of a string
Sha1(str string) []byte
// HmacSha1 Calculate the sha1 hash of a string using the HMAC method
HmacSha1(key string, data string) []byte
// HmacSha1ToString Calculate the sha1 hash of a string using the HMAC method, outputs lowercase hexits
HmacSha1ToString(key string, data string) string
// Sha256 Calculate the sha256 hash of a string
Sha256(str string) []byte
// HmacSha256 Calculate the sha256 hash of a string using the HMAC method
HmacSha256(key string, data string) []byte
// HmacSha256ToString Calculate the sha256 hash of a string using the HMAC method, outputs lowercase hexits
HmacSha256ToString(key string, data string) string
