# rsa-modified (rsam)

Supports additional functionalites and important stuff must be done in some corner cases and some specific applications

Modified package for RSA encryption and decryption to allow **large** message encryption and decryption and to **allow encryption through private key and decryption through public key** and signature through public key and private key and vice versa. i.e. Additional functionalities to the existing crypto package

### Installation 

```shell

go get "github.com/gossl/rsam"

```

### Usage

```go

import  (

  "bytes"

  "fmt"

  

  "github.com/gossl/rsam"

)

func main(){

  priv, pub, err := rsam.GenerateKeyPair(2048)

  if err != nil {

    panic(err)

  }

  msg := []byte("hello world")

  ciphertext, err := rsam.EncryptWithPrivateKey(msg, priv, sha256.New())

  if err != nil {

    panic(err)

  }

  plaintext, err := rsam.DecryptWithPublicKey(encrypted, pub, sha256.New())

  if err != nil {

    panic(err)

  }

  if !bytes.Equal(msg, plaintext) {

   panic(nil)

 }

}

```
