Linked.PM\n\nA single-file browser-based application which turns your private messages into \nclickable, encrypted links.\n\nSet a shared secret (password) with your friends and send \"linked\" PMs through \nunencrypted channels (email, sms, facebook etc) or paste them into documents \n(also in the form of QR code). \n\n[ ![Screenshot of Linked.PM application](img/screenshot.png) ](https://linked.pm)\n\n## Example \n\nThe QR code below contains a Linked PM:\n\n[ ![QRCode](img/example-qrcode.png) ](https://linked.pm/#AQ83Ok5xYqYr1lx8ZwHRCyIQ7G8BBY0PZPhJDjoonQfIJsFUlA34m9qJj+3ZEjwagnFOVC0ALWWAhOGT51go3b4I9cL8rgytd023LFQFlwXC/X2oVP6NEjK4Phv5jdXHKC34yg==)\n\nThe password is *topsecret*.\n\n## Details\n\nMessages are encrypted using AES-CCM cipher (Advanced Encryption Standard (AES) \nin Counter with CBC-MAC Mode (CCM)) and 256 bits key computed from your password \nusing 10000 rounds of PKDF2 key derivation algorithm.\nDuring each encryption additional parameters like salt and IV (initialization vector) \nare randomly generated, so it is unlikely that the same message with the same password \nwill generate the same link next time you use linked.pm.\n\nThe ciphertext (with salt and IV) is stored in the hash part of URL and its processing \nis exclusively client-side with no participation from the server (browsers do not send \nthis part of URL to the server). \n\nIn fact you can save linked.pm application (a single file) on your desktop \nand use it offline.\n\n## Build\n\nTo build the application follow these steps:\n\n```\ngit clone https://github.com/simplito/linked-pm.git\ncd linked-pm\nnpm install\ngulp\n```\n\nThe resulting apllication file can be found in `dist/index.html`.\n\n## License \n\nThe MIT License (MIT)\n\nCopyright (c) 2016 Simplito Inc.\n\nPermission is hereby granted, free of charge, to any person obtaining a copy\nof this software and
