# Crypto
> This package can be used to **Encrypt**, **Decrypt** and **Sign** data using **Asymmetric** algorithms in php.
the below algoritms can be used:
- RSA
- DSA
- DH
- EC
## Install
Via Composer
``` bash
$ composer require shetabit/payment
```
## How to use
here is a simple encoding/decoding example.
```php
$crypto = new Crypto;
// generate private key
$privateKey = $crypto->createPrivateKey();
echo $privateKey;
// generate public key
$publicKey = $crypto->createPublicKey($privateKey);
echo $publicKey;
$data = 'a simple text';
// encrypt, plain data
$encryptedData = $crypto->encrypt($publicKey, $data);
echo $encryptedData;
// decrypt, encrypted data
$decryptedData = $crypto->decrypt($privateKey, $encryptedData);
echo $decryptedData;
```
#### Create private key
you can create a private key like the below
```php
$crypt = new Crypt;
$privateKey = $crypt->createPrivateKey();
echo $privatekey;
```
the below algorithms can be used:
- RSA: use **Crypto::OPENSSL_KEYTYPE_RSA**
- DSA: use **Crypto::OPENSSL_KEYTYPE_DSA** (not completely supported by PHP OpenSSL)
- DH: use **Crypto::OPENSSL_KEYTYPE_DH** (not completely supported by PHP OpenSSL)
- EC: use **Crypto::OPENSSL_KEYTYPE_EC** (not completely supported by PHP OpenSSL)
```php
$crypt = new Crypt;
$privateKey = $crypt->createPrivateKey(Crypto::OPENSSL_KEYTYPE_RSA);
echo $privatekey;
```
#### Create public key:
a public key can be generated using a private key
```php
$privatekey = '-----BEGIN EC PRIVATE KEY-----
MIHuAgEBBEgC1SvKxAMTrXYmC9CV+euaL8KVemuuU6I9A5moUh4HgTzESYt35lgc
CiwMetwIaB9RHFM7869D4rClXvnxFy91nMklcY7IsCmgBwYFK4EEACehgZUDgZIA

qTvrA+usw5pjfZmqE4hHlFVdIaIb7r2m8w2OEZTfsfxQjRzY6uE9P3711NWdZdP2
Rg==
-----END EC PRIVATE KEY-----';
$crypt = new Crypt;
$publicKey = $crypt->createPublicKey($privateKey);
echo $publicKey;
```
#### Encrypt data:
- data must be in string format.
- you need a **valid public key** to encrypt data.
```php
$publicKey = "-----BEGIN PUBLIC KEY-----
MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAzLBs9Y2+QSr8l5LV8beY
nidHPHhM0/zMy1V7CiTWQyQVyxsZKHQJZGP+zJNovSH+KG9wfUe5XnC7qVDU80Bi

FwIDAQAB
-----END PUBLIC KEY-----";
$data = 'this is a simple text';
$encryptedData = $crypto->encrypt($publicKey, $data);
echo $encryptedData;
```
#### Decrypt data:
- you need a **valid public key** to decrypt data.
```php
$privateKey='private key';
$encryptedData = 'encrypted data';
$decryptedData = $crypto->decrypt($privateKey, $encryptedData);
echo $decryptedData;
```
#### Sign data:
- data must be in string format.
- you need a **valid public key** to sign data.
```php
$privateKey = "-----BEGIN PRIVATE KEY-----
MIHuAgEBBEgC1SvKxAMTrXYmC9CV+euaL8KVemuuU6I9A5moUh4HgTzESYt35lgc
CiwMetwIaB9RHFM7869D4rClXvnxFy91nMklcY7IsCmgBwYFK4EEACehgZUDgZIA

Rg==
-----END EC PRIVATE KEY-----";
$data = 'this is a simple text';
$signature = $crypto->sign($privateKey, $data);
echo $signature;
```
#### verify signature:
- you need a **valid public key** to verify data.
```php
$publicKey = "-----BEGIN PUBLIC KEY-----
