CryptoLight

Library for digitally signing media (Photos or Videos) on the device.

  • Generate digital encrypted media signatures via private key
  • Signature verification of files via public key
  • Easy encryption and decryption of texts
  • Confirmation if signature belongs to media, ensuring media was not contaminated

Installation

Add it in your root build.gradle at the end of repositories:

allprojects {
 repositories {
  ...
  maven { url 'https://jitpack.io' }
 }
}

Add the dependency

dependencies {
        implementation 'com.github.dori871992:CryptoLight:1.1.0'
}

Usage

Initialize in onCreate() of Application class

public class LibraryApp extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        CryptoLight.init(this);
    }
}

*It will generate keypair of public key and private key

Private and public keys can be accessed like:

 String publicKey = CryptoLight.getPublicKey(this);
 String privateKey = CryptoLight.getPrivateKey(this);

Generate signature for file:

 File file = new File(Environment.getExternalStorageDirectory().getPath() + "/DCIM/Camera/IMG_20190603_164516.jpg");
 String filePath = file.getAbsolutePath();
      
 File signatureFile = CryptoLight.generateDigitalSignature(this, filePath);}

Verify signature:

  • filePath {path of file (photo or vide) to to be verified}
  • signatureToVerify {path of signature file of photo or vide to to be verified against}
  • publicKeyFilePath {path of public key file where signanture was generated from}
 boolean verified = CryptoLight.verifySignature(this, filePath, signatureToVerify, publicKeyFilePath);

Encryption and Decryption:

  String encryptedMessage = CryptoLight.encrypt(this, "Dorian Musaj is coming amigos!");
  String decryptedMessage = CryptoLight.decrypt(this, encryptedMessage);  //output will be "Dorian Musaj is coming amigos!"
