eикrуpт, inspired by cryptii, is a web page where you can encrypt/decrypt messages using algorythms such as AES, DES, etc. Everything is done in your browser using javascript, cryptojs, tea.js and steganographyjs. Nothing is send to the server (there is no back-end).
Disclaimer: The algorithms do not provide 100% secure encryption. Additionally, in-browser encryption is a problem of itself.
