Install EndCryptor. After sending one and receiving two verification emails you can start sending encrypted emails to other users of EndCryptor – this is an automated process. They also can send to you.
The verification emails check that you are in control of your email address. After verification your email address and long term public key are put into the Web Directory of EndCryptor. If someone wants to start sending encrypted emails to you he/she must know your email address – it is typed into EndCryptor and the Web Directory is searched for the public key associated with the email address.
