Detached signature

A detached signature is like a special code that you can use to prove that something is really from you. To make a detached signature, you take some important information about something (like a document or an email), then use a special program to mix up that important information and make a unique code. You can then share that code with anyone who needs to know that the thing is from you. Like, if you wrote a document and wanted to show someone that it was really from you, you could use the detached signature code to prove it.
