XRSA

OpenSSL RSA Encryption, Decryption, and Key Generation. Java, Php GoLang Support, Large Data Support.

Installation

Php

Make sure openssl extension is enabled. Just copy php/src/XRsa.php and php/src/helpers.php to your project. Alternatively, you can use composer to install:

composer require liamylian/x-rsa

GoLang

Make sure your golang version is greater than 1.10.3. Just Copy golang/xrsa/xrsa.go to your project, or use command:

go get github.com/liamylian/x-rsa

Java

Just Copy XRsa.java to your project

Usage

Php

    $keys = XRsa::createKeys(2048);
    $rsa = new XRsa($keys['publicKey'], $keys['privateKey']);
    
    $data = "Hello, World";
    $encrypted = $rsa->publicEncrypt($data);
    $decrypted = $rsa->privateDecrypt($encrypted);
    $sign = $rsa->sign($data);
    $is_valid = $rsa->verify($data, $sign);

GoLang

    publicKey := bytes.NewBufferString("")
    privateKey := bytes.NewBufferString("")

    err := CreateKeys(publicKey, privateKey, 2048)
    if err != nil {
        return
    }
    xrsa, err := NewXRsa(publicKey.Bytes(), privateKey.Bytes())
    if err != nil {
        return
    }

    data := "Hello, World"
    encrypted, _ := xrsa.PublicEncrypt(data)
    decrypted, _ := xrsa.PrivateDecrypt(encrypted) 
    sign, err := xrsa.Sign(data)
    err = xrsa.Verify(data, sign)

Java

    Map<String, String> keys = XRsa.createKeys(2048);
    XRsa rsa = new XRsa(keys.get("publicKey"), keys.get("privateKey"));
    
    String data = "hello world";
    String encrypted = rsa.publicEncrypt(data);
    String decrypted = rsa.privateDecrypt(encrypted);
    String sign = rsa.sign(data);
    Boolean isValid = rsa.verify(data, sign);
