Using the application you can upload a public key on your KeyBase.io profile. This public key is safe, as it is your address on KeyBase.io.

Once you have a public key you can upload the encrypted string to your clipboard. You can also select a public key from your KeyBase.io profile or search for it by typing its name.

There is a public key for every person on KeyBase. After the public key is uploaded the text is automatically decrypted. To save the text to a file you can use the "Share File" feature from the context menu. To share the file on any other site you need to copy the URL of the page. The text can also be exported to the clipboard. To get the URL of the page you can use the "Share Page" feature from the context menu. To view the page source you can use the "View Page Source" feature.
