I recently put a pet-project of mine called Burn-Notice into public βeta.
Burn-Notice: Simple, Secure, Encrypted one-time Information
It’s like messages for Inspector Gadget, everything will self-destruct! So if you happen to send sensitive information over the web, you can use this tool to exchange passwords, credit-card numbers, key-codes, voucher-codes etc… After the recipient got the message, the information get’s deleted right away.
All information is stored encrypted on the server and can only be decrypted with knowledge of a passphrase that is entered by the sender. The recipient of a message can only decrypt the message with knowledge of the passphrase - the shared secret!
I would love to get feedback from you, please check out burn-notice.me
