About Vernam Cipher
Using this app, you can create and share secret keys that you can then use to encrypt and decrypt messages using the Vernam Cipher. This implementation acts as a one time pad as it discards the part of the key used to encrypt/decrypt messages.

Version 1.6

Excellent app, happy to find a recently updated one time pad encryption app. Edit** I have received the update and being able to send via text solves the problem I had of not being able to choose the appropriate app, the app was installed, but it still wouldn't list when trying to send via file. Excellent project, I appreciate the reply with regards to the request, thank you!
