CuteDog Messenger

Use this app to perfectly encrypt your sensitive messages.

Use SMS or another app to send and receive messages. It works by taking a password and URL, ideally for a large file such as a high resolution image and morphs your message based on those inputs. Only someone with both your password and URL will be able to decrypt the message, following the "One-time Pad" method of unbreakable cryptography. https://en.wikipedia.org/wiki/One-time_pad

Best practices:

Do not reuse the same password + URL combination unless you increment the message count field. Do not send your password, URL, or message count in the same mode you send your encrypted message.
