Lockbin is a web application for sending private email messages and files. It's free! People use it to send things like credit card numbers or confidential information.

Why can't I just use email?
Lockbin ends message persistence, which means your email message will not be backed up on email servers or stored in backup files. Network sniffers can also spy on your email traffic while in transit. Use Lockbin to obscure the content of your message and avoid these potential hazzards to your privacy.

How does it work?
No registration is required to use Lockbin. Your message and file attachments are protected by strong AES-256 bit encryption and your secret password. You invent the password and deliver it to the recipient using a phone, text message, instant message, homing pigeon, or as a last resort... another email. When your message is retrieved, it is decrypted in the recipient's browser and erased from Lockbin's database. Uncollected messages are destroyed after six months.

Can you see my message on your server?
No. The message is encrypted using your password before it is stored in our database, and the password does not remain on our servers. No unencrypted files are stored on our server. We have no way to decrypt your message, and we can't help you if you forget the password.

Is it safe?
Pretty darn safe. Nothing is perfect, and neither is this, but it is certainly safer than sending sensitive data directly through email. The largest threats to this method would be 1)capturing the sender or recipient's password by spoofing the Lockbin website, or 2)a screen capture virus that images the decrypted message on the recipient's computer. Neither attacks are likely, but are a possibility.

Will you collect my email address and spam me? How do you make money?
We absolutely will not spam. If we did nobody would use this service.
How do we make money? Well, we don't. At present we are content to let the service grow unencumbered by the money problem. A limited number of sponsors help to defray our monthly server costs. We may offer a premium tier of services at a later date.

I am a spy. Can I use Lockbin to send stolen secrets back to the motherland?
No. Lockbin must only be used for legal purposes.

Where can I learn more about protecting my privacy on the internet?

Is AES-256 Encryption Strong?
If you use a strong password it is. AES-256 is not known to have been cracked through brute force. It's been said by people smarter than us that it would take a 4 GHz computer 4.5865*10^59 years to search just half the key space, a period of time in which most scientists believe the universe will cease to exist long before that happens.

Can I use Lockbin on my mobile?
Yes! You can send encrypted emails from your mobile phone with the new Lockbin Mobile Service at https://lockbin.com/m
