XOR
This utility app allows you to encrypt and decrypt text messages using a secret key. It generates a string of random characters that can only be deciphered with the correct key, making it ideal for secure communication or hiding sensitive information.
- Text encryption and decryption
- Millions of secret keys
- Save favorite keys
- Built-in sharing functionality
- Cross-device compatibility (iPhone, iPad, Mac)

Never have your secret messages exposed ever again. Simply type your message into the text box, choose one of millions of secret keys, and watch as XOR generates a string of seemingly random characters. These wacky characters actually encode your entire original message and are impossible to decipher without knowing the secret key that you chose. XOR can be used to hide secret messages, securely store passwords, or mess with friends. XOR allows you to save your favorite keys, has built-in sharing functionality, and works on your iPhone, iPad, and Mac. All in a seamless, native experience.
