Your ECA certificates are bundled as a set: one used for signing and authentication and the other for encryption. You will receive an email from VeriSign containing your PIN and a pickup URL for your ECA digital certificates. Be sure to pick up both certificates.
Go to VeriSign ECA customer support to learn how to use your ECA certificates for signing and encrypting email by configuring your email program or browser.
Backup your ECA digital certificates in case you need to move them to a new computer, replace a corrupted ID, and for safe keeping. Store the floppy disk or CD in a secure place such as a safe or lockable cabinet.
