InterFAX is a secure fax-to-email service, supporting SSL access, strong encryption and HIPAA compliance. For an introduction to InterFAX's encryption features, see our encrypted fax solution page.
This page explains how to enable encryption for fax confirmations sent by InterFAX. See also our documentation on encrypting inbound fax messages and encrypting outbound fax messages.
Enabling Encryption for Fax Confirmations Sent by InterFAX
This feature will add another layer of security to your communications with InterFAX. When you send faxes through the InterFAX email-to-fax service, you may choose to receive confirmations. You can select to receive confirmations on success of a transaction, on failure, always, or never.
These confirmations are standard email messages which are returned to the original sender address of the email-to-fax. Normally, these messages are sent in plain, unencrypted format. However, it is possible encrypt these messages. To encrypt messages sent to you, we need to have your digital signature.
Send InterFAX Your Public Key 'Signature'
This step only needs to be done once. Send a signed (not encrypted) email message to digitalid@interfax.net from the email address from which you intend to send your faxes. InterFAX will automatically associate the sender address with this digital signature. (Note that this will encrypt inbound fax messages, if inbound service is active. For more see comment below*).
Any confirmations which are returned to this address will from now on be encrypted. To cancel encryption, send an unsigned email message to digitalid@interfax.net.
* Note: This is also the way to request that inbound faxes be forwarded to you in encrypted form. If you do NOT wish to activate inbound fax message encryption, complete the instructions above, then login to your account, click Preferences -> Incoming, then click "Security Settings" next to the appropriate email address. The deselect "Sign Messages" and "Encrypt Messages".
