Step 1. Add the JitPack repository to your build file

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

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.worldline-spain:t21-crypter-android:v_1.0.4'
	}

	dependencies {
		implementation("com.github.worldline-spain:t21-crypter-android:v_1.0.4")
	}

	<dependency>
	    <groupId>com.github.worldline-spain</groupId>
	    <artifactId>t21-crypter-android</artifactId>
	    <version>v_1.0.4</version>
	</dependency>


                            
    libraryDependencies += "com.github.worldline-spain" % "t21-crypter-android" % "v_1.0.4"


                            
    :dependencies [[com.github.worldline-spain/t21-crypter-android "v_1.0.4"]]

Readme

T21 Crypter Library for Android

This library allows to encrypt and decrypt sensible data in your applications. Tipically used for token encryption, if you want to secure your application and ensure anyone can steal the token of your users, you should use this library.

Supported data types

String

Features

Encryption (AES/CBC/PKCS5Padding) with a random IV
Decryption (AES/CBC/PKCS5Padding)

Import:

Maven

dependency>
  <groupId>com.tempos21.t21crypt</groupId>
  <artifactId>t21_crypter_android</artifactId>
  <version>1.0.5</version>
  <type>pom</type>
</dependency>

Gradle

compile 'com.tempos21.t21crypt:t21_crypter_android:1.0.5'

<dependency org='com.tempos21.t21crypt' name='t21_crypter_android' rev='1.0.5'>
  <artifact name='$AID' ext='pom'></artifact>
</dependency>

Usage:

Encryption:

/**
 * This key should be dynamic
 */
private static final String KEY_TOKEN = "RANDOM_STRING";

String textToEncrypt = "whatIWantToCrypt1234";
final Crypter crypter = CrypterFactory.buildCrypter(CryptMethod.AES, KEY_TOKEN);
String encryptedText = crypter.encrypt(textToEncrypt);

Decryption:

/**
 * This key should be dynamic
 */
private static final String KEY_TOKEN = "RANDOM_STRING";

String textToDecrypt = "rAvceqEKRR3uG7jltp7EccfMobmipUgvp142pnmQB2g=";
final Crypter crypter = CrypterFactory.buildCrypter(CryptMethod.AES, KEY_TOKEN);
String decryptedText = crypter.decrypt(textToDecrypt);
