Crypto Helper

Extremely fast and incredibly secure encryption tool that can be used as a second layer over any existing or future application. The simple design does not save any data that can be used against your security, once you quit the app, all data you don't want in clear text will be deleted. More features are added as soon as I verify their security. I designed the app to be so secure that even security minded people would feel safe using it, and I have succeeded.

Current features:
Customized algorithm based on the Vigenère cipher
Custom key enhancing 512 bit hash making keys more secure with no possibility of collisions
Frequency analysis page that tells you how many of each character are used
Optional "Noise injector" which injects random noise to further confuse attackers and defeat frequency analysis based attacks
Optional Hexadecimal encoder for forwards compatibility with characters not found on most keyboards (accents, emoji, etc)
Random key generator

More features are in testing:
AES128 and AES256 layers
RSA and SSL based public key encryption
File and folder encryption
Key file support
NFC / Bluetooth key sharing
UI tweaks
Performance boosts just to see how fast and secure this can be made
Quantum computer proof layers for all future ciphers
Custom character tables
Data compression layer
