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. Source code is available at https://github.com/jeffisaak/vernam_cipher Changelog (from v1.1 onwards): Version 1.10 - Upgraded Android SDK and Gradle versions. - Updated the 'about' text. Version 1.9: - Fixed a couple of bugs that were causing crashes Version 1.8 - Added a message to the user indicating their password protected secret keys are broken (terribly sorry everyone) Version 1.7 - Fixed a bug that was causing secret key importing to fail. - Fixed a bug that was causing password-protected secret keys to fail. Version 1.6 - Fixed a bug that was causing the number of bytes remaining in a password-protected secret key to be misrepresented - Added the display of the cipher text when decrypting a message. - Added the ability to view a secret key (long press on a secret key in the list, then select 'View secret key'). Verison 1.5 - Fixed a bug that caused the app to crash when decryption was attempted with no secret keys generated Version 1.4 - Fixed a bug that caused the app to crash on startup for new installations Version 1.3 - Added ability to share encrypted messages as text or as a file - this opens up new sharing options - Miscellaneous code cleanup - Added a link to my donation page (yes, shameless self-promotion) Version 1.2 - Fixed an error connecting to random.org Version 1.1 - Fixed a rather crippling Nougat bug
