I haven't used special algorithm here,

There is a problem (Look here) with Base64 class in Android and (Oracle)Java SDK. They have both this class but has some little differences in methods and different packages.

I have taken Oracle's version and has created this lib. Buy the help of it you can use Oracle's Base64 in Android application. It eases your encryption and decryption process with the same function in Android application and in pure Java application.

• In Oracle's SDK - java.util.Base64
• In Android SDK - android.util.Base64
• In this Lib - com.mobapphome.simpleencryptorlib.Base64 - This is like Oracle's version but works in Android and in pure Java(Oracle SDK)

Download the demo app from this link - Demo App. You can easly test the lib's functionality.

Library has SimpleEncryptor class. It has three main static methods:

• SimpleEncryptor.newInstance("key")
• SimpleEncryptor.encode("str for encrytion")
• SimpleEncryptor.decode("str for decrytion")

Look following sample how to use library:

Encryption in Kotlin:

val simpleEncryptor = SimpleEncryptor.newInstanceOrRetunNull("Sample SecretKeyPhrase")
val encrypted = simpleEncryptor!!.encodeOrReturnNull("Text to encode")

Encryption in Java:

SimpleEncryptor simpleEncryptor = SimpleEncryptor.newInstance("Sample SecretKeyPhrase");
String encrypted = simpleEncryptor.encode("Text to encode");

Decryption in Kotlin:

val simpleEncryptor = SimpleEncryptor.newInstanceOrRetunNull("Sample SecretKeyPhrase")
val decrypted = simpleEncryptor.decode("Vm1hSLhhDsCMJTyd4A==")

Decryption in Java:

SimpleEncryptor simpleEncryptor = SimpleEncryptor.newInstance("Sample SecretKeyPhrase");
String decrypted = simpleEncryptor.decode("Vm1hSLhhDsCMJTyd4A==");

To import library to you project add following lines to project's build.gradle file. The last stable version is 1.1.3

repositories {
    maven { url 'https://dl.bintray.com/hummatli/maven/' }
}

dependencies {
    compile 'com.mobapphome.library:simple-encryptor-lib:1.1.3'
}

Thats all. If you have any probelm with setting library please let me know. Write to [email protected]. I will help.
