Obtaining Someone Else's Digital ID

"VeriSign's Repository"

In order to encrypt an e-mail message sent to someone, you must have their digital ID. If someone has sent you a digitally signed e-mail, their digital ID is probably stored in your mail client. 

One may obtain someone's digital ID, i.e. public key, in a number of ways.

  • When you receive a digitally signed message, you receive the sender's public key.
    • Mail clients may automatically store the public keys of all senders.
    • You may have to selectively choose to save an individual's public key. 

    •  
  • An individual's public key may be obtained from a directory service.
