Simple implementation of XOR Encryption/Decrypting in various languages, including:

• C
• C#
• C++
• Dart
• Groovy
• [Java](Java (Android compatible)/XOREncryption.java)
• JavaScript
• Objective-C
• Python

This implementation goes beyond the basic single-key model to use multiple keys in a particular sequence, making it that much more difficult to brute-force.

In these examples, I'm encrypting the same string with the same keys in order to keep consistency with the output, and to demonstrate that an encrypted string from a C program can be decrypted in a Java application, or any combination, so long as the keys remain the same.
