README

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);
