AS2, AS3, AS4, ebMS, OFTPv2, RNIF, and other protocols require use of a digital certificate for encryption and signing purposes. Other security features within the Cleo Harmony, Cleo VLTrader, and Cleo LexiCom applications (for example, XML Encryption within the Mailbox Packaging tab) also require a digital certificate. See Configuring mailbox packaging. As a prerequisite to setting up a trading relationship, you must aquire a digital certificate from your trading partner. See About Certificate Management for information on digital certificates.
The Cleo Harmony, Cleo VLTrader, and Cleo LexiCom applications provide certificates for some of the pre-configured hosts, but most of the pre-configured hosts require you to obtain the signing/encryption certificates directly from the trading partner.
You and your trading partner must agree on the method of certificate exchange. You can exchange certificates through a web site, a courier service, regular mail, or as attachments through electronic mail. The mailbox Notes tab might be preconfigured with specific information concerning certificate exchange with a particular trading partner.
Once you have received the trading partner’s certificates, you can register the certificates with the Cleo Harmony, Cleo VLTrader, or Cleo LexiCom application by either saving the files directly in the certs\ directory or by importing the certificates . See Importing certificates.
Finally, identify the signing/encryption certificates in the mailbox. For example, see AS2 Mailbox: Certificates Tab. Use the mailbox wizard and follow the steps to set the trading partner signing/encryption certificates. See Using the wizard to create a host or mailbox.
