Izemail

Encrypt and sign your e-mail messages, just by pressing the Send button in your e-mail program with Izemail. No need to exchange encryption keys or certificates, no need to go through complex enrollment procedures. The program allows you to send an encrypted and signed message, and all you need to know is their e-mail address. This program uses widespread standards for e-mail encryption such as S/MIME and PKI, making it compatible with any technology that supports S/MIME or PKI. It can read, decrypt and verify messages sent by these other systems. This program takes your message, encrypts it and delivers it to the recipient. If recipient doesnt already have an encryption key, the program makes sure they get one. Also, the software can use X.509 certificates issued by any CA that complies with PKI standards. It does not require you to use Izemail certificates.
