## cnigma

The golang implementation of [cnigma](https://github.com/keng42/cnigma)

### Usage

```sh

go get github.com/keng42/go/cnigma

```

#### AES

```go

import (

	"fmt"

	"log"

	"github.com/keng42/go/cnigma/aes"

	"github.com/keng42/go/cnigma/aes/types"

)

func main() {

	aesgcm, err := NewAES(types.ModeGCM, types.DefaultKey, "my-password", types.Base64)

	if err != nil {

		log.Fatal(err)

	}

	ciphertext, err := aesgcm.EncryptText("hello world @ 2020", "")

	if err != nil {

		log.Fatal(err)

	}

	plaintext, err := aesgcm.DecryptText(ciphertext, "")

	if err != nil {

		log.Fatal(err)

	}

	fmt.Println(plaintext)

	// Output: hello world @ 2020

}

```

#### RSA

```go

import (

	"fmt"

	"log"

	"github.com/keng42/go/cnigma/rsa"

	"github.com/keng42/go/cnigma/rsa/types"

)

func main() {

	priv, err := rsa.LoadPrivateKey("../testdata/rsa-private-pkcs8.key")

	if err != nil {

		log.Fatal(err)

	}

	r, _ := rsa.NewRSA(types.Hex)

	r.PrivateKey = priv

	r.PublicKey = &priv.PublicKey

	msg := "hello world @ 2020"

	// Sign message with private key

	sig, err := r.Sign(msg)

	if err != nil {

		log.Fatal(err)

	}

	fmt.Println("sig", sig)

	// Verify message with public key

	verified, err := r.Verify(msg, sig)

	if err != nil {

		log.Fatal(err)

	}

	fmt.Println("verified", verified)

	// Encrypt text with public key

	ciphertext, err := r.Encrypt(msg)

	if err != nil {

		log.Fatal(err)

	}

	fmt.Println("ciphertext", ciphertext)

	// Decrypt text with private key

	plaintext, err := r.Decrypt(ciphertext)

	if err != nil {

		log.Fatal(err)

	}

	fmt.Println("plaintext", plaintext)

}

```

## random

A simple app for generating random strings.

### Usage
