# Luzifer / go-openssl
|
||
|
|
|
||
|
|
`go-openssl` is a small library wrapping the `crypto/aes` functions in a way the output is compatible to OpenSSL / CryptoJS. For all encryption / decryption processes AES256 is used so this library will not be able to decrypt messages generated with other than `openssl aes-256-cbc`. If you're using CryptoJS to process the data you also need to use AES256 on that side.
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
```
|
||
|
|
go get github.com/Luzifer/go-openssl
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage example
|
||
|
|
|
||
|
|
The usage is quite simple as you don't need any special knowledge about OpenSSL and/or AES256:
|
||
|
|
|
||
|
|
### Encrypt
|
||
|
|
|
||
|
|
```go
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
"github.com/Luzifer/go-openssl"
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
plaintext := "Hello World!"
|
||
|
|
passphrase := "z4yH36a6zerhfE5427ZV"
|
||
|
|
|
||
|
|
o := openssl.New()
|
||
|
|
|
||
|
|
enc, err := o.EncryptString(passphrase, plaintext)
|
||
|
|
if err != nil {
|
||
|
|
fmt.Printf("An error occurred: %s\n", err)
|
||
|
|
}
|
||
|
|
|
||
|
|
fmt.Printf("Encrypted text: %s\n", string(enc))
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Decrypt
|
||
|
|
|
||
|
|
```go
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
"github.com/Luzifer/go-openssl"
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
opensslEncrypted := "U2FsdGVkX19ZM5qQJGe/d5A/4pccgH+arBGTp+QnWPU="
|
||
|
|
passphrase := "z4yH36a6zerhfE5427ZV"
|
||
|
|
|
||
|
|
o := openssl.New()
|
||
|
|
|
||
|
|
dec, err := o.DecryptString(passphrase, opensslEncrypted)
|
||
|
|
if err != nil {
|
||
|
|
fmt.Printf("An error occurred: %s\n", err)
|
||
|
|
}
|
||
|
|
|
||
|
|
fmt.Printf("Decrypted text: %s\n", string(dec))
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## Testing
|
||
|
|
|
||
|
|
To execute the tests for this library you need to be on a system having `/bin/bash` and `openssl` available as the compatibility of the output is tested directly against the `openssl` binary. The library itself should be usable on all operating systems supported by Go and `crypto/aes`.
