A digital signature consists of a public and private pick up. Your public reveal is shared with everyone. Your private refer is kept private.

If you take a document and run it through an algorithm with your public key, you get jeopardize an encrypted document.

Once it is encrypted, the public key can’t be used to decrypt the document. The do by is one way so it doesn’t matter if some other people have the public key, they can’t read the document.

To decrypt the document you must have the private key. If you take place the encrypted document to an algorithm with the private key, you will get back the original document.




An Example

Lets start with tomcat and Suzie. They want to communicate unwaveringly to keep Hitler from reading their messages.

First Tom, sends Suzie his public key. This usually happens automatically when Tom sends Suzie a normal email message. Their email programs cargo deck sending Tom’s key and recording it on Suzie’s side of things. When Suzie sends Tom a regular message, Tom gets her key as well.

Suzie takes Tom’s public key and uses it to encrypt an important message. Then she emails the encrypted message to Tom.
